#Freshwater gobies

[aquariuminfobureau]

The eleotrid clade of gobies are popular aquarium fishes down under, where a number of species inhabit the freshwaters. As a clade of fishes, the eleotrids are underappreciated by aquarists outside of Australasia. One of the three relatively popular species in the aquarium trade, is the visually striking Hypseleotris compressa, the empire or carp gudgeon, also known as the empire fish.

The range of the H. compressa extends from the northern half of mainland Australia in the south, and up into parts of nearby New Guinea. This stunning goby inhabits slow-flowing and still freshwaters, extending only into the low salinity reaches of estuaries, meaning that this is a freshwater fish. There it lives among aquatic plants and woody, submerged debris, and forages for mostly tiny prey amongst detritus, leaf litter, and vegetation.

According to sources, H. compressa measures up to 12 centimeters or almost 5 inches in length. Although I have never seen one exceeding 3 inches, and a more typical size would be 5 centimeters, or 2 inches. Male H. compressa establish territories in which the females spawn, and the males both guard and tend to their nests until hatching occurs. Spawning occurs during the warmer months. The spawn and hatchlings are tiny, and as far as I know, they have never been reared in the aquarium.

In Australian English, the eleotrid or sleeper gobies are colloquially known as the 'gudgeons', although this word, ironically, first referred to a demersal, northern hemisphere carp of the genus Gobio, that was as familiar to the first white Australian settlers, as are the eleotrids to their naturalized descendants. Within the tree of life, gobies are only very distantly related to the carps, and the eleotrid gobies are very successful in the Antipodean freshwaters.

The type locality for H. compressa is the Clarence River of subtropical New South Wales. There the pH is about 6.7 to 7.7, depending on the time of the year, and the average pH is close to 7. More generally, the rivers and creeks in the surrounding Clarence-Moreton bioregion, have yearly average pH values, from 6.6 to 7.8. as regards their water temperature, they are usually 15 to 30 degrees centigrade.

The iconic and multi-volume Baensch freshwater atlas, claims that this species tolerates temperatures of 10 to 30 degrees. This is not very inaccurate but exposure to ambient temperatures as low as 10 degrees, is both seasonal and temporary. Some sources claim this fish tolerates temperatures as high as 35 degrees centigrade, but temperatures in the creeks where H. compressa lives, are not normally this warm, and it should not be attempted in the aquarium.

H. compressa and similar gobies are carnivores. This species consumes insects and other tiny arthropods, primarily cladocerans and copepods, and is regarded as zooplanktivorous. This fish willingly consumes defrosted foods of an appropriate nature. Sources claim this species eats algae, but this seems unlikely to be deliberate given the general diets of Hypseleotris sp. gobies. They do ingest detritus whilst they are feeding, so the merely incidental ingestion of algae is likely in H. compressa and it's kin.

As a predator, H. compressus is not a danger to adult community fishes, although it is known to eat fish fry, including acts of cannibalism. It is a peaceful aquarium denizen, but such 'gudgeons' do prefer a quiet tank without boisterous, demersal tankmates, such as very active catfishes or loaches. The male fish should not be cohabited together.

These little fuckers are round gobies. They are a freshwater goby that's invasive in Michigan, and they're in the nearby lake. They're distinct from the four native species due to their fused pelvic fins (middle pic) and a big black dot at the rear of their front dorsal fin. Though some other gobies have spots on their fins, NO Michigan-native species has a fused pelvic fin. These guys are very aggressive feeders and are very good at outcompeting native gobies.

They're also extremely good at stealing bait off big hooks as people on the docks reel in their lines. In particular, the bastard in the bottom photo stole my bait two days ago, so I caught him and filleted him for Bug.

Today, after acquiring smaller hooks, I went back and got 16 more, and educated several other fishers about their invasive nature. I got two turned over to me by others, and caught 14 more myself.

One man wandered over and asked why I was catching them on purpose. It was too much trouble to explain my feelings about invasive species, so I just told him, one of them stole my bait two days ago. He stopped watching my bobber and boggled at me and goes:

"You're doing this for revenge?"

So now there's some guy in town that thinks I am exacting revenge upon fish kind for a single stolen worm.

Two new species of freshwater goby (Teleostei, Gobiidae) from the Upper Youshui River, Chongqing, China

Lingzhen Li, Chaoyang Li, Weihan Shao, Suxing Fu, Chaowei Zhou

Abstract

Two previously unknown species of Rhinogobius have been discovered in the streams of the Upper Youshui River, within the Yuan River Basin, Xiushan County, Chongqing, China. These new species are named as  Rhinogobius sudoccidentalis  and Rhinogobius lithopolychroma. Phylogenetic analysis based on mitochondrial genomes revealed that R. sudoccidentalis is genetically closest to R. reticulatus, while R. lithopolychroma shares the greatest genetic similarity with R. leavelli. Morphological distinctions allow for the clear differentiation of these species. Rhinogobius sudoccidentalis sp. nov. is characterized by having VI–VII rays in the first dorsal fin and I, 8–9 rays in the second dorsal fin. The longitudinal scale series typically consists of 22–24 scales, while the transverse scale series comprises 7–8 scales. Notably, the predorsal scale series is absent and the total vertebrae count is 12+17=29.  Rhinogobius lithopolychroma sp. nov. can be distinguished from other species by the presence of 13–15 rays on the pectoral fin. Its longitudinal scale series ranges from 30 to 33 scales, with no scales in the predorsal area. The total vertebral count is 30, with 12 precaudal and 18 caudal vertebrae. The head and body of this species are light gray with irregular orange markings on the cheeks and opercle. Through morphological and molecular analyses, it has been confirmedthat R. lithopolychroma and R. sudoccidentalis represent novel species within the Rhinogobius genus.

[wishfishy]

When I first heard that a new Endless Ocean was going to be released, I was incredibly excited. Just absolutely over-the-moon excited. You see, Endless Ocean 2: Blue World (also called Endless Ocean 2: Adventures of the Deep) is one of my favourite games of all time. Scratch that: it is my favourite game. It was far from perfect, but I loved it dearly and happily sank hundreds if not thousands of hours into it.

EO2 is a diving game for the wii that was released in 2010, and I have never been able to find a game quite like it. The main story was a bit cheesy, but charming and engaging, with a bevy of likeable if occasionally one-note characters, and the game itself had surprising depths (diving pun fully intended). The game had 12 different diving maps in 6 locations and while the specific areas were fictitious, they were based on very real places (the South Pacific, Mediterranean Sea, Red Sea, Arctic and Antarctic Oceans, as well as a freshwater river in the Amazon) and this was reflected in the species found in each area, with a few exceptions here and there.  You could explore shallow coral reefs, a sunken castle, ancient temples, abyssal depths, a kelp forest, sandy beaches, riverbanks, hidden coves with murals, and much more. You also had a small private island as a hub location, a personal reef you could decorate, and a public aquarium which you could fill with any of the non-legendary species you discovered.

Speaking of which, the game featured 340 different species of marine and freshwater fish, sharks, rays, marine mammals, penguins, shore birds, reptiles, crustaceans, cephalopods and other invertebrates. Some of these also had different models for young or different genders. You could find truly miniscule species that most other diving games overlook entirely in zoom-spots (such as gobies and nudibranchs), and you could interact with most by feeding, touching or even riding in the case of large marine life. And on top of this you could also find legendary creatures, which could be individuals of extant species with unusual colouring or size, or even extinct species, and could be exceedingly hard to find but entirely rewarding.

This is already getting to be much too long but on top of all this you could customize your diver character, buy things for your island hub, decorate and populate a private reef to propagate and release fish, create various aquarium exhibits, discover a great many side-quests, upgrade equipment, take and sell photographs, heal sick animals, search for and sell salvage, find collectable coins, train dolphin partners, take requests for guided tours, dolphin shows, salvage and photos, dodge or placate aggressive sharks, and more that I am probably forgetting. It’s been a while since I’ve played the game, as I no longer have a wii and don’t have the first clue on how to emulate games on my PC. All this is to say that this game was something special, and I have never been able to find anything remotely close to it. And seeing as how the last one was released almost 15 years ago, I had long given up hope for an Endless Ocean 3.

And then lo and behold, a trailer dropped from out of nowhere for Endless Ocean Luminous! And it was releasing in a month! Holy Shit! What!? Yes!

But alas, the more information came out about the game, the more that excitement started to wane. A focus on multiplayer? Procedural generation? Only one map? The only character being an AI that sounded like all those awful tiktok voices? To be clear, I wasn’t expecting Luminous to be the next GoTY. I wasn’t even expecting it to be an exact replica of EO2, or continue the storyline. If it had even a fraction of what I liked about the previous game I was going to be one happy camper. I assumed that the marketing was focusing on the multiplayer aspect instead of the single-player story, that hopefully the procedurally generated map was exclusive to that multiplayer. Surely the single player mode would extend past what little was shown in the trailers. Some things seemed promising, such as an advertised 500+ species, and even more prehistoric marine life. But again, alas, what I have seen since the release is the barest and palest reflection of what I enjoyed about the previous game. I could understand cutting some content, such as the dolphin training and shows, considering the controversy of cetaceans in captivity. But it seems like there is no aquarium, no central hub of any type, no characters beyond the aforementioned AI and a single faceless diver, salvage reduced to a single click, an incredibly reduced story consisting mostly of scanning fish, no ability to feed or interact with fish and fish behaviour also seems to be quite reduced. At least photography still appears to be in the game, though its unclear to what point. Are there still photo requests? The ability for some critters to swim along with or attach to your diver looks cute at least. But everything I’ve watched so far just feels so… lifeless. Empty. As if the whole game was AI generated, which I’m at least %75 sure isn’t the case.

But I’m left kind of baffled by the direction that this game was taken in. I’ve been trying to find any information about it’s development with little to no success. Why the focus on multiplayer to the exclusion of a single player story beyond the bare minimum? What lead to the choice to have a single, procedurally generated map instead of separate, smaller, but more scientifically accurate maps? Or even a single smaller but purposefully designed map? Was this game more like the previous games at any point in its conception or development or was it always intended to be such a departure?

Spectember D26: Break a biological record

Some hundreds of millions of years far into the future around 300 million years hence, after the formation of a big supercontinent, one that was not predicted to form, a lot of existing terrestrial and marine fauna look so alien compared to the animals that once man witnessed as the difference is as much as a human being would have to the first terrestrial tetrapod. Phylogenetically speaking many of those animals would be related to something like a crown, a snake, a varanid, a goby, a frog, a bat and so on but they are totally anatomically, morphologically and physiologically far from those, mammals and birds are a fraction of what they were, more mole or reptile like, varanids and frogs suffered of varied radiations and now they have been as much diverse as how dinosaurs and synapsids went through the Mesozoic and Cenozoic, and small fishes survived and radiated from freshwater species over and over from different mass extinctions, and just for matter of convergence they looked something like the modern species man saw, but they aren’t anatomically close to those.

In land mammals are just small and ectothermic creatures, in the ocean however one lineage managed to thrive as large swimmers, is not like any other group however, they have lost their forelimbs, their tails barely help them to swim and often depending of the species they have a rigid fluke or a seahorse-like prehensile tail, they managed to re-evolve some structure similarly to gills from a part of a nose cavity, a result of its proper ontogenic development as they did born not fully developed. These aren’t descendants of placentary mammals, but marsupials, a lineage that stood almost unchanged for many dozens of millions of years in the Americas and took a turn after the major calamities through the last 200 million years that drove their group to become reptile like, adopt peculiar adaptations for their lethargic metabolism and ended up in this stage, these aquatic animals were the last descendants of the opossums.

The Scorn Figoeq are a twisted form of the more seahorse-like herbivorous relatives that lives in the surfaces, living at depths of 4000 to 5000 meters under the surface is by far the deepest species of tetrapod that has ever lived, the deepest mammal to have diver so low under the ocean. It adopted the lifestyle of the already gone anglerfishes as well some other deep-water fishes, is among the last of an experimental lineage of the Figoeqs (Derivation of Figoeqqus or "shaped like horse") that tried to become pelagic planktonic feeders which ended up becoming extinct in the last 50 million years, remaining as a relic of that group. With 25 cm long, anything that could be considered mammal like only is exposed by looking at the embryo of this species as it starts with the basics of mammal anatomy, but reaching adulthood they resemble a mix of a jelly and a bizarre abyssal fish, with their short body, large head with a deep gelatinous cover that protects part of its head and eyes that now grow inside the flesh, with long dorsal spines that helps it to stabilize while swimming, their long hind flippers that look more like ray fins, and the tail that has grow a fluke to push it slowly across the darkness of the abyss.

MONSTROUS FUSION LINKS AS FISH AND OTHER AQUATIC CREATURES IF MONSTROUS FUSION WERE FISH OR OTHER AQUATIC CREATURES

All characters belong to @monstrous-fusion!!! This is my other mermay contribution. Each Link has a different place in the world of cultural inspiration, so at least one of the fish included for each is endemic to that region. Endemic means it is native to that specific area and not found (naturally) anywhere else in the world!! It’s really cool. There are some fish that are endemic to a singular lake!!!! Big lakes, but still one singular lake!!!! Or one reach of a tributary stream!!! It’s super cool.

Anyway. FISH!!!!! Image descriptions at the very bottom! :D

IMAGE ID: Images are the names of each link and then a saltwater fish and a freshwater fish. Each fish has the common name, the common name in the native language of wherever it is found, and then the scientific name. The fish are listed below. Since I am posting this on mobile I only have an English keyboard, so I am only including the common names in the ISO Latin alphabet in the descriptions.

[fishyfishyfishtimes]

I'm a bit shy asking this so I'll stick to anon for the time being. I visited a pet store today and they had the cutest little fish roaming at the bottom of one of their tanks gulping and spitting out sand. I couldn't find the species on the side with the names and tried to do some research and I think it may be a Sand Sifting Goby? All I saw was that they require salt water and that it seemed to feed off whatever was in that sand. I'm genuinely obsessed with this little guy and took plenty of videos, but I don't want to make bad decisions and get one without proper knowledge and research. I was curious to know if you had any facts or tips to help me out? Thank you 🩷

Sounds adorable!! Sand sifting gobies are a whole group of species that come in a variety of colours, all of them looking quite sweet! No doubt the fish was captivating to look at doing its little sand sifting :D

You say you do not wish to make a bad decision and simply impulse buy one without research, which is a good mindset to start from. Fish are not a monolith of animals, they're a large and diverse group of species, each one having their own specific criteria for keeping. I don't know if you've kept fish before or not anon, but I will be giving a general explanation that lets a person who hasn't get started: fish require specific water parameters (temperature, pH, general hardness and calcium carbonate concentration, salinity, etc.), substrate (thickness at the bottom, colour, roughness), plants (density of plants, real or fake, etc.), decor (will the decor scratch or accidentally harm the fish, do they like to hide, etc.), tankmates (of their own species or of different species, or lack thereof), food (specific dietary preferences and restrictions), lighting (harsh or dimmed, amount of light a day), so many things! Freshwater and saltwater aquariums are also different and require different equipment.

The very first thing I recommend you do is go to the pet store (or contact them through social media or email) and ask them what species the goby is. This way you can do research on the specific species instead of sifting through general information about all sand sifting gobies, which may be completely different from our dear little friend at the pet store! That's actually the crux of obtaining a fish or another aquatic life companion: RESEARCH! Soooo much research. You must research your finned friend so much it's starting to feel ridiculous and your family is asking you if you're "still planning on that fish or..?". Look up care guides and fish forums, watch YouTube videos, gather up all the information you get. Some of it contradicts itself, which is why it's important to look to many many sources. Try seeing the newest ones and see what parameters and suggestions are most common. That's only the beginning, though: if you've never owned a fish before, you need to learn about all these aquarium-keeping terms and how to maintain an aquarium, what you need for an aquarium, how to cycle it, etc.. Actually, that's probably best to do before you look up care guides, now that I think about it... Or do both at the same time, that's what I did when I was planning my shrimp tank. See beginner's guides to saltwater fishkeeping, on several sites, move onto more advanced guides and learn the terminology. Learn why these parameters matter so much, or why and how to cycle your tank. Weigh the pros and cons of having plants or some plant species, research different substrates, see what tanks and lights and filters are smartest for you, learn about aquarium pests. Try to find a good middle ground for what's sensible for you and what's the best for your pet; we keep animals for our enjoyment, but we also want to make sure they're having their best time too! Make a list for all the items you need, see how much different options cost, make a budget. Research the water parameters of your city or town, or test the water yourself. See what needs to be done to it so it's suitable for your animal. I've never kept a saltwater tank so I don't know the specifics of it myself, but if you wish to be a saltwater aquarium keeper you must learn! It's a lengthy process, but I went through seven months of preparation before I got my dwarf shrimps. This included my research (I don't have an estimate for how many articles and forums I looked through but my "Shrimps" playlist I made in preparation has 52 videos of just cherry shrimp and aquarium-keeping educational videos), shopping for equipment and plants and setting everything up, and cycling my aquarium. Dear folks in my notes also informed me that saltwater tanks and setups tend to be more expensive than freshwater setups!

Maybe at some point you find that the setup and equipment are simply too expensive, or incompatible with your lifestyle or living situation, or you change your mind for another reason during the preparation process. And that's valid and okay! You took the time to learn and what you learned was just that: it wasn't meant to be. It's much better than getting an animal without preparing and only finding out afterwards that you're incompatible in some way. Learning about these things won't be for "nothing" either, as now you have the valuable knowledge of how to keep fish and an aquarium! It may prove useful later in life if you eventually do obtain an aquarium, or you can become the resident fish knower (very rewarding). You may also decide to look into freshwater gobies, as they are gobies all the same but easier to care for! Please take a look at the folks in the notes and their lovely info.

Hope this helps anon! Perhaps you were wishing for a fish facts -format post, but my measly one-to-four sentence daily fish facts do not a species expert make. Instead I want to give out a guide on how to get started on your goby-keeping journey. I hope it works out for you, I wish you good luck! :)

[thenativetank]

whats ur fav fish :3

My fave fish is the coelacanth for sure. But that's neither a native fish, nor suitable for a fish tank so that's not a fun answer! I'm gonna infodump on my fave native fishes below!

Starting with the iconic Sunfishes - so many to love! Orangespotted Sunfish are probably my favorite in Lepomis for their beauty, small size, and peaceful nature (Warmouths are second in this genus). I also love my Bluespotted Sunfish for many of the same reasons, and there's a part of my that find Fliers infinitely interesting. They look like Lepomis/Pomoxis hybrids and I love them.

The Fundulus killifishes are all fantastic. Mummichogs have been among my favorite fishes kept, but Banded, Longnose, Seminole, Marsh, Striped, and Gulf killies are all hardy, with subdued beauty.

Despite all the invasive species, we only have one native Cichlid, the Rio Grande/Texas Cichlid - a real beauty of a fish that is a typical pugnacious American cichlid and is relatively easy to place in aggressive communities.

Darters are so cool - they are so unlike many of the fish you see in stores and are behaviorally fascinating. We have SO MANY beautiful darters like Greenside and Candy darter complexes, but my vote is for Tesselated. Because I can find those locally. Fun fish for sure.

Pretty much every Pike is a solid choice - but the Esocidae family also includes Mudminnows! Described as "cigars with fins" they are supremely cool fish that are small and peaceful - their moving of all fins out of sync to stay hovering in the tank column is a treat to watch.

Similarly, every Gar is fantastic in my book, with my vote going to the Longnose Gar for its impressive range and salinity tolerance.

Our minnows are winners, hands down, with both the silvery ones and the colorful ones being awesome fish. Lots of great choices for tank keeping too. But I'm going with the Mountain Redbelly Dace here. Beautiful fish for sure!

Mosquitofish are comforting. Around here, you find them EVERYWHERE. I typically catch a few no matter where I fish. They look like Guppies without the vivid colors, but most still get some pleasant iridescence to them and in Florida you can find lovely black and white mottled variants that are just so cool.

Our native freshwater catfishes are cool but I love our saltwater catfishes. Called crucifix fishes for the shape of their skull bones, both the Gafftopsail and Hardhead Catfishes are neat social animals with a wide salinity tolerance.

The gobies are a family of winners as far as I'm concerned but the Violet Goby takes the cake for being a MEGA weirdo - this nearly two foot long fish wouldn't hurt a fly (a fry?) and so so so odd. Who wouldn't love them?

Atlantic Spadefish may not have the great juvenile coloration of their Platax relatives, but they are smarty pants fish that get big and are very active. I've seen populations in the Georgia Aquarium that are spellbinding to watch.

Hogchokers are Soles that have a terrible name but are also the most common fish in the Chesapeake Bay. I'd love to catch one someday!

I feel like I should stop here - but how do you not include our native puffers, bowfins, madtoms, damselfish, morays, salmon, sturgeon, Mollies, Pupfish, or Angelfish? We have one native tetra too! Isn't that neat?

The Hong Kong goby

Rhinogobius duospilus (formerly R. wui) and its species complex, are among the more popular aquarium gobies for freshwater tanks. True R. duospilus grow to 4 centimeters, or over 1 and a 1/2 inches, and are traded as dwarf dragon, red-cheeked or especially Hong Kong gobies. It is unlikely that great effort will have been made, to accurately identify the fish at species level.

In the aquarium, R. duospilus favors a, water temperture, of 16 to 25 degrees centigrade. Although these subtropical gobies are sometimes described as coldwater fishes, in fact they rarely experience tempertures below 15 degrees in the wild. This species has a broad tolerance of pH and hardness values, but the water must be well oxygenated.

This is because R. duospilus inhabits brook environments, where it is sympatric with hillstream loaches, such as Beaufortia. These are freshwater environments, above the influence of the tides, so no salt should be added to the water. A pH of 5.6 to 6.4 might be inferred from the origins of R. duospilus.

Two male Rhinogobius will be mutually antagonistic, although the females show no such difficulties, and several may be housed per male, to create a social environment. Rhinogobius are simply disinterested in any tankmate that is neither food nor a threat. Feeding R. duospilus is a matter of provisioning defrosted, meaty, invertebrate-based food for them. Unlike some freshwater goby species met in the trade, such as members of Stiphodon, the species belonging within Rhinogobius are carnivorous.

Alright! for this shrimpo sunday we have my favorite shrimp! the Pistol Shrimp!1!!

the alphaeidae or pistol shrimp or snapping shrimp (or as i like 2 call em cowboy shrimp :] ) are a family of shrimps characterized for their asymmetrical claws, the biggest one which is capable of causing a LOUD snapping sound, *thanks to the phenomenon of cavitation!!! (mantis shrimp can also cause this phenomenon!!) that happens when the motionless pressure of a liquid (water in this case!) its below the liquid's vapor pressure that form tiny vapor filled bubbles on the liquid, when these bubble experience the higher pressure of the liquid they collapse1!! and generate shock waves (that are literally boiling water thanks to the amounts of pressure) this way being able to knock over their prey! all thanks to the mechanism on their claws!!!*

these funky guys can move its claws at an amazing speed of 97km/hr!, this species haves about 38 or moree genera, the 2 most common would be alpheus and synalpheus, with species of the number of well over 250 and 100,

Most snapping shrimp dig burrows and are common inhabitants of coral reefs, submerged seagrass flats, and oyster reefs. While most genera and species are found in tropical and temperate coastal and marine waters, Betaeus inhabits cold seas and Potamalpheops is found only in freshwater caves!

When in colonies, the snapping shrimp can interfere with sonar and under the sea communication. The shrimp are considered a major source of noise in the ocean! wich is pretty epic i think

Sum facts i find pretty cool about the pistol shrimps :D

🦐.Some pistol shrimp species share burrows with goby fish in a mutualistic symbiotic relationship. The burrow is built and tended by the pistol shrimp, and the goby provides protection by watching out for danger. When both are out of the burrow, the shrimp maintains contact with the goby using its antennae. The goby, having better vision, alerts the shrimp of danger using a characteristic tail movement, and then both retreat into the safety of the shared burrow. This association has been observed in species that inhabit coral reef habitats.

🦐.Eusocial (its the type of kinda society that ants n bees have) behavior has been discovered in the genus Synalpheus. The species Synalpheus regalis lives inside sponges in colonies that can number over 300. All of them are the offspring of a single large queen shrimp. The offspring are divided into workers who care for the young and predominantly male soldiers who protect the colony with their huge claws. (I find it very peculiar how i can't really find any information of other pistol shrimp genus that haves this cuality so this is pretty cool i think)

🦐.Pistol shrimp have the ability to reverse claws. When the snapping claw is lost, the missing limb will regenerate into a smaller claw and the original smaller appendage will grow into a new snapping claw. Laboratory research has shown that severing the nerve of the snapping claw induces the conversion of the smaller limb into a second snapping claw. The reversal of claw asymmetry in snapping shrimp is thought to be unique in nature.

hope u guys enjoyed the shrimpo facts sunday!! :D [edit*] [tyms to @cruel-singer for the notes on the phenomenon of cavitation that is how the snapping shrimp's claws actually work!! really ty gamer :DD]
