apparently pjotv twt was being weird about book!Percy's eyes being green because they don't think the ocean can be green (???) so consider this a sequel to my Grace siblings eye colors post and here is some visual references of green water for all your Percy inspo needs:

And for reference, the water around New York-ish where Percy is usually is somewhere around this color:

or some alternatives:

or here is a nice hazel green if you want his eyes more on the brown side, which is very common in freshwater ponds and streams:

or if you want him to have totally brown eyes - water rich in tannins will appear brown, greenish-brown, or very dark brown - this is sometimes called "blackwater" due to often appearing very dark or having low visibility:

40 gallon long update~

Everything is going well in this tank apart from the odd bit of algae here and there.

The new pearl gourami is getting on nicely. Though it is a bit picky and will only eat flakes. He is quite shy and is still nervous when I come up to the tank. Hopefully, he will get used to me soon!

The bamboo shrimp is growing, too! I feed it some crushed up flakes and the powder from my rapashy.

The old dominant harlequin rasbora, who got his nose torn off in a fight, is doing well. He's eating fine, and there appears to be no infection going on. So I think he's okay.

Chiggy, my peppered corydoras that was born deformed, is doing good, too. She doesn't come out much, preferring to chill amongst the Val with the other corys.

Big Mama is still big. I'm still hoping she'll give me some eggs soon, but it's been a while since I've seen any breeding action from them.

The otocinclus and siamese algae eater are doing well, too! Doing their jobs and keeping the tank tidy~

Attention-Worthy Links for November 30th, 2024

[addfish]

Last year I could not access my 90l tank to maintain it properly due to building work and as a result it suffered what I like to call Algaegeddon! My tank was plagued with hair algae, green spot algae and black beard algae, also resulting in a loss of a lot of shrimps, fish and snails.

So this year I have had to start over! I removed most of the badly affected leaves, but the algae still kept coming! I bought a treatment only to find out that it was harmful to shrimp and snails, luckily I realised before I used it! Then i bought another which says it was safe for fish/shrimps/snails, but only worked on one type of algae, (green water) which was no good! I finally found Colombo Algisin which treats all kinds of algae and is safe for fish, snails and shrimp! It's a long process to treat it, but it is working well!

I also used Algisin in the 30l Aquacube. I packed the tank away last year and recently restarted it, and although I bought new plants and everything was clean it developed algae from new tank syndrome. The algae is gone now after 2 doses of the treatment, so it's time to buy some more plants!

Wet Beast Wednesday: Christmas tree worm

Merry Christmas from the ocean! For this festive occasion, I’ve chosen to cover an animal that certainly has the spirit of the season. The Christmas tree worm is the person who keeps their Christmas lights up all year of the sea and today we’re going to see what makes them tick.

(Image: the crown of a Christmas tree worm. It appears as two stalks emerging from amongst coral polyps. Small feathery, appendages emerge from the stalks in a spiral formation going up them. They are yellow, with brown tips. A smaller, round structure is near the base of the trees. End ID)

The Christmas tree worm (Spirobranchus giganteus) is a polychaete worm of the tube-building fan worm clade Sabellida. While they are called giganteus, that’s only relative to other fan worms as they max out at about 3.8 cm (1.5 in) long. Being tube worms, they build a tube of calcium carbonate that they live in. This tube provides protection for the worm, who can retreat into it if threatened by predators. Polychaetes are defined by the paired bristle-like chaetes on each body segment, which are often used for locomotion. Tube worms like the Christmas tree worm lack these kind of locomotive appendages as they spend their entire lives in their tubes.

I couldn't find a full-body picture of a Christmas tree worm outside of its tube, so this is the best you get. (Image: Serpula vermicularis, a member of the same family of tube worms as the Christmas tree worm, removed from its tube. It is a short, segmented worm with a plug on a stalk and a crown consisting of long, feathery tentacles arranged differently than those of a Christmas tree worm. End ID)

The feature that gives these worms their common name is a pair of feathery, spiraling structures that emerge from the head and look quite a bit like tiny, colorful fir trees. These structures, called crowns, are heavily modified version of mouth appendages called prostomial palps. The feathery bits are tentacles called radioles. The crown is usually the only part of the worm visible, with the rest of its body safely in the tube. The crown is used both for feeding and respiration, as it can perform gas exchange with the water like gills. Christmas tree worms, like other fan worms, are filter feeders. They expose their crows to the water and wait for edible plankton and bits or organic detritus to get caught by the radioles. Cilia then transports the food down to the mouth. Christmas tree worms have a modified radiole called an operculum that acts like a lid to the front of the tube, closing it off when the worm retreats. The crown also has light-sensing structures, allowing it to detect light and shadow. The visual capabilities of these eye spots is poorly studied. The crown makes up about a third of the body length and can come in a wide variety of colors. It can regenerate if damaged.

(Image: a blue-crowned Christmas tree worm emerging from yellow coral. End ID)

Christmas tree worms are found across most of the world, from the Caribbean to the Indo-Pacific, in tropical waters. They are coral reef dwellers who live in burrows built into had corals. Brain coral species are their preferred hosts, but they can live on other corals and have been reported living in sponges and on giant clams. Christmas tree worms certainly have a symbiotic relationship with the corals, it's debatable whether that relationship is parasitic, commensal, or mutualistic. They may damage nearby polyps and could spread harmful algae (that seems to be an open question), but I found sources suggesting they improve water flow around the coral, which could benefit it. When they sense a threat, the worms will rapidly retract into their tubes. Some time later (which can be seconds to minutes), they will cautiously emerge again. Worms living on crowded corals seem to be more timid, taking longer to emerge again. Christmas tree worms are broadcast spawners who release their gametes into the water. Fertilized eggs hatch quickly into larvae who must find their way to a coral and start their burrow. Christmas tree worms can live up to 30 years.

(GIF: a bright yellow Christmas tree worm retracting into its tube. The full retraction takes less than a second and leaves only a hole covered by the operculum. End ID)

Christmas tree worms are considered to have a stable population, but as they are dependent on corals, threats to reefs are threats to them. Thus, global climate change is a major threat to their survival. Predators of the worms include fish, starfish, and other worms. They are not of commercial interest to humans, but are popular among divers and have entered the aquarium trade.

My beautiful blue child whom I love

Sorry anyone who has been around me the past three days has been subject to me randong about photosynthesis in animals due to me going "I wanna make a guy who can do photosynthesis and also control light waves to a certain extent."

Everyone appreciate my Amphibious daughter rn, I could go on for like a straight up hour about all my scifi sciencey bullshit about how this species developed and what their environment is like. (I get more excited about that than the actual character I fear)

I have so many thoughts but I'm really bad at expressing them but behold my shitty Star Trek oc fan made alien guy I suppose

Basically they are an amphibious species that evolved in water with low levels of oxygen, this caused them to have a symbiotic relationship with a species of algae that found its way into their cells and consumed the nitrogenous waste from mitochondria, while producing oxygen in the eggs allowing them to continue to grow. (See Yellow Spotted Salamander for real life instance of this.)

Over time they evolved into quite the apex predators mostly living in water, but due to shifts in the planets climate and atmosphere they became land animals and build civilizations close to the water.

The star system they are in is pretty far out of federation space so a different alien species native to their solar system lands on their planet before they are NEARLY evolved enough and due to the planets rich resources in being a largely tropical environment they set up outposts there

Because of this the species (Who I'm tentatively calling the Z'oldar) never really evolved their own technology, trading and utilizing other species in their quadrant, and civilization migrated largely to the mountainous regions of the planet where outposts were located for work and better access to the goods brought into this planet

Long and short of it K'prin works at one of these outposts as a bartender for most of their adult life, having been raised by the workers there, when the Borg show up and totally fuck up the whole (Already technologically limited, compared to the federation anyways) solar system and start assimilating Z'oldar outposts first, K'prin manages to find their way into a small impulse shuttle craft that was definitely stolen from the Federation like a solid 15 years ago and got traded to this side of the galaxy.

With absolutely 0 flying skills, Borg related chaos and an old ass shuttle head together with scrap metal, K'prin totally the course and it is left with 0 rations and minimal life support drifting through space when suddenly (for the plot okay guys listen) a wormhole opens up near by and sucks then it, leaving her in weird worm hole time stasis for like 10 years before spitting her back out in the dead center of Federation territory

Who then logically freak the fuck out cause how the fuck did a unidentified ship on IMPULSE POWER get this far into federation territory, and why.

Anyways theres more but I realized this is hella long already and I kinda feel bad for any unsuspecting mutual who just happens to click on the read more. I'll explain more if anyone asks and can go into more detail about K'prin specifically, I have so many thoughts, character ggrrr
