#Coldwater tropicals

Sewellia lineolata is one of the ballitorid hillstream fishes, that are endemic to Asia. They are not "plecos" or loricarids, nor suckers or catostomids, as they are often confusingly labelled in aquarium retail. Loricarids and catostomids are found in other parts of the world. Often they are called a loach, which is fair, because they nest deeply within the traditional, pre-cladistic assemblage, called Cobitidae. Historically, they were regarded as distinct from the loaches.

S. lineolata are collected from Southeast Asian upland waters, which must always be well oxygenated, though not neccessarily as fast moving assume sources indicate, because these fish are found in pools beside riffles, as, well as in the actual rapids. In the wild, they live on gravel, bedrock, and sand substrates, with few submerged plants. Sewellia make an excellent focus for a biotope setup.

This species grows to about 6 centimeters, or 2 and a 1/4 inches. The trade names for S. sewellia, are the reticulated, tiger, and gold ring hillstream fish. For all I know, other species may be traded under these names. Care for all the imported species and morphs of Sewellia sp , is believed to be the same.

S. lineolata have small mouths for fishes their size, and feed on algae, biofilm, and very small invertebrates. In the aquarium this species will eat algae wafers, micro pellets of the sort offered to shrimp, and defrosted invertebrate based foods. These are not considered difficult fishes to feed, and they have no ability nor inclination, to prey on ornamental tank cohabitants.

I don't know the water parameters where they are collected from the wilds, but in the aquarium, their proper care is well established. Their water ought to be moderately hard, and its pH should be about neutral, with the temperture a bit lower than is usual for a tropical tank, with somewhere between 20 to 23 degrees centigrade being a good temperture to maintain.

In the wild they are diurnal, and spend time grazing and foraging, in unshaded water, so I imagine some daytime temperture tolerance greater than that - but its important to know, they experience cooler tempertures by night, and should not be confused with tropical fishes. Permanent exposure to tempertures over 24 degrees, has been noted to lead to emaciation.

They also experience seasonality in the wild, not only of temperture but of rainfall, with run off depositing organics into the water during the rainy season, surely affecting the water chemistry they experience. My point is, these are hardy loaches that tolerate a range of tempertures and water chemistries, only if the needs of oxygenation are met.

But the ability of fish like Sewellia sp. to temporarily tolerate high tempertures, on a daily or seasonal basis, should not be willfully misunderstood and abused, by people who want yo treat them as though they were tropical fishes. These are "coldwater tropicals".

Cool to see a coldwater rocky shore adapted starfish just grasp your hand like that, the tropical reef species we have here just really harden and once relaxed, glide over your fingers

Yeah the starfish at the aquarium here will just Grab anything including people. In the case of this picture, which I’m guessing is what you’re referring to;

I had picked him up for some kids to pet and as I was giving them Fun Starfish Facts he just realized oh. I can climb this.

And suddenly I had a starfish bracelet

I think I've said this before BUT. Since many fancy goldfish are bred and raised in warm water and seem to actually prefer warmer water than their coldwater carp ancestors, the temperature difference between them and tropical fishes isn't that much of an issue. But seeing goldfish being kept with anything other than more goldies still feels so wrong. I think it's because goldfish have such different care needs? Less decor, more food, more large water changes. They are SO much more domesticated compared to tropical fish, which are usually not far derived from their wild counterparts. Plus they are clumsy, and grow large enough to accidentally eat many tropicals.

or like here is another game i played some in 2022: megaquarium

here’s the thing with megaquarium: it is not really an aquarium simulator. it’s much more of a “manage throughput of a theme park” simulator a la theme park, rollercoaster tycoon, etc. just the themes are aquarium boxes

things that are not covered in the simulated mechanics in megaquarium:

animals reproducing. no matter how many fish of the same species you have in the same aquarium, you will never get new fish. you gotta buy or trade for each new fish. this also means you never have to worry about overcrowding

animals dying of old age. with the above this means that fish populations never rise or fall unless you mess up and starve them to death / otherwise make their tank uninhabitable

animals eating plants. you can’t e.g., defray food pellet costs by planting an edible plant in the aquarium with a fish that eats it. all food comes in the form of pellets from food boxes

aquarium plant growth. some fish do grow, but no plants grow; they have constant stats and are effectively just another kind of decoration. so, again, no seeding a nwe aquarium with cuttings; you have to separately buy every plant you put down. some plants do impact water quality, but the game never asks you to engage with that by e.g., making a no-filter aquarium

anything to do with substrate. no deep substrates to foster different kinds of bacteria, no needing to ‘cycle’ a tank before fish are ready to be placed inside. there are 'live rocks’ you can put into a tank, which do some filtering, but again that’s a static bnus, and also you can put 'live rocks’ next to 'rocks’ and the rocks will never be colonized & turn into live rocks. “filter quality” is a numeric value that is the sum of all attached filters and the tank is just instantly at that water quality level

anything to do with different kinds of water. there are tropical fish, which require heaters, and coldwater fish, which require coolers, and there are light-needing corals and light-avoiding fish, but you never have to e.g., add tannins to a tank to make it suitable for fish that want blackwater conditions, or saltwater/brackish/freshwater fish that require certain salt levels

anything to do with water flow. you can’t pump water from a heavily-populated tank into a heavily-planted tank to increase the water quality; if you hook several tanks up to the same set of filters they just evenly split the filter values.

so like the level of 'simulation depth’ there is very shallow; you’re basically just placing mostly-inert fish-objects together with wholly-inert decoration-objects. aquariums can be better, by the metrics of the game, but they can't really be different. there's not a lot of room for personal judgement and design, because the rating metrics are so tight and the design space is so small. all the complex mechanical interactions are about controlling customer flow. so it’s less a game about fish simulation and more a directing-people simulator with some fish-themed objects

I got the chance to touch a coldwater jellyfish last week... Their bells are much more solid than I would have expected after years of visiting my local aquarium, watching them float around like dainty lace flowers.. My friend likened the sensation to petting a stingray... If you've ever done that, either.

The animal is fleshy with a thin mucousy layer protecting it. It was very cold. I don't know why I expected body heat. Even sharks and rays are warmer than this, due to the tropical water they swim in.

The peppered Corydoras

Just a reminder that the 22 or 23 degree temperature range that is often suggested for the popular peppered or mottled Corydoras, Corydoras paleatus, are based on year-round averages for its natural range, in the Lower Parana and La Plata, Argentina. In reality the region is not tropical, and the climate is seasonal, with winter temps dropping as low as 18 degrees, and summer temps soaring as high as 28 degrees.

This origin actually gives C. paleatus a wide tolerance of ambient temperatures, though those temperatures too close to the higher and lower ends of that range, should not be maintained permanently. Whereas there is a reason, countless hobbyists have maintained this fish in perfect health, year round, at tank temperatures of 22 to 25 degrees. These are not the water temperatures preferred by flag or discus cichlids, for example, but 24 degrees is the standard temperature for running tropical community aquaria.

For C. paleatus the pH ought to be set to around 7, or slightly over, as per their wild origins. These are not a fish from tropical blackwaters, nor hardwater lakes. Care in the aquarium is otherwise as standard, for the other popular Corydoras species. The aquarium substrate should be fine sand, food should be dried and defrosted items suitable for small, largely insectivorous catfishes, and the fish themselves should be maintained in a group, lest singular corys become less bold.

I have more tropical fish experience than goldfish experience but what I do know is that a) You're going to want to get at least a 29 gallon tank--I know it sounds huge but even a single goldfish needs that much space to stay healthy, they can get very very large and they're super prone to ammonia buildup in the water, and if you think you ever want to get Amber a friend, it's +10 gallons for every goldfish past the first one. b) Goldfish are coldwater fish! You don't need a heater like you do for tropical fish but you DO need a filter (again: ammonia). Don't bother paying for a starter kit bc that will come w a heater you dont need, buy the tank and filter separately. (Also I recommend looking for used tanks on Craigslist or whatever, can b much cheaper than new, just make sure it's actually water-safe and not a terrarium. Filter should b bought new, though.) A 30 gallon tank needs a filter w around a 120 gallon per hour flow rate, filters are usually marked for a tank size. Ppl at the store can tell u how to cycle the tank before putting her in it. c) In the meantime, to avoid ammonia buildup, you kinda have to be the filter yourself, so do a 50% water change at least every other day in the vase. The big tank will need water changes too, but only ~10% every other week and a 30% change every couple months or so if u have a good filter. Good luck to you and to Amber! -fish

A lot of this is sounding about right, which is probably a good sign! Thanks for the advice :)

The Optimal Temperature for a Fish Tank - Ensuring a Healthy Aquatic Environment

Maintaining the ideal temperature in a fish tank is vital for the health and well-being of its inhabitants. Fish are ectothermic creatures, meaning they rely on the environment to regulate their body temperature. As responsible fish keepers, it is our duty to provide the optimal temperature conditions that mimic their natural habitats. In this article, we will delve into the importance of maintaining the right water temperature in a fish tank and explore the optimal temperature range for various types of fish.

Understanding the Significance of Water Temperature

Water temperature plays a crucial role in the overall health, growth, and behavior of fish. Different species have varying temperature requirements, and even slight deviations from their preferred range can have adverse effects on their physiology. Here are some key reasons why maintaining the optimal water temperature is essential:

Metabolism and Digestion: Fish are cold-blooded animals, meaning their body temperature is determined by their environment. The metabolic rate and digestion of fish are directly influenced by water temperature. The right temperature promotes efficient digestion, nutrient absorption, and overall metabolic functions.

Oxygen Levels: Water temperature affects the solubility of oxygen, with colder water holding more dissolved oxygen than warmer water. By maintaining an optimal temperature, you ensure that the fish have access to an adequate oxygen supply, crucial for their survival and activity.

Disease Prevention: Consistently maintaining the optimal temperature range can help prevent the onset of diseases in fish. Fluctuations or extremes in temperature can weaken their immune systems, making them more susceptible to infections and stress-related illnesses.

Reproduction and Growth: For many fish species, temperature variations are closely linked to their reproductive behavior and growth rates. A stable and appropriate temperature range encourages spawning, hatching, and the healthy development of fry.

Optimal Temperature Range for Different Fish

It's important to note that different fish species have evolved in various aquatic ecosystems with specific temperature requirements. While this article provides a general overview, it is always advisable to research and consult species-specific guidelines for precise temperature recommendations. Here are some common temperature ranges for popular aquarium fish:

Tropical Freshwater Fish: Most tropical freshwater fish thrive within a temperature range of 75°F to 80°F (24°C to 27°C). This includes popular species like guppies, tetras, angelfish, and mollies. However, some specific species may have slightly different requirements, so researching their natural habitat is crucial.

Coldwater Fish: Coldwater fish, such as goldfish and koi, prefer temperatures between 65°F to 75°F (18°C to 24°C). They can tolerate cooler temperatures but are sensitive to sudden temperature fluctuations. Extreme temperatures can stress coldwater fish and lead to health issues.

Marine Fish: Marine fish species have diverse temperature preferences depending on their origin. Generally, the optimal range for marine aquariums is between 74°F to 82°F (23°C to 28°C). However, it is crucial to research the specific requirements of each species, as some tropical marine fish may require higher temperatures.

Betta Fish: Betta fish, also known as Siamese fighting fish, thrive in warmer water. The ideal temperature for bettas ranges from 76°F to 82°F (24°C to 28°C). Maintaining consistent warmth is essential to their overall health and vibrant colors.

Maintaining the Optimal Temperature

To ensure the optimal temperature for your fish, consider the following guidelines:

Use a Reliable Aquarium Heater: Investing in a high-quality aquarium heater with a built-in thermostat is crucial for temperature control. This allows you to set and maintain a consistent temperature within the desired range.

Regular Monitoring: Use an accurate and reliable thermometer to regularly monitor the water temperature. Check it multiple times a day initially to ensure stability and adjust the heater accordingly.

Avoid Temperature Fluctuations: Sudden temperature changes can shock and stress fish. Keep the fish tank away from drafts, direct sunlight, and heat sources like radiators or air conditioning vents to prevent sudden temperature fluctuations.

Research and Adapt: Before introducing new fish species to your aquarium, research their specific temperature requirements. Make any necessary adjustments to the overall tank temperature to accommodate the needs of the new inhabitants.

Maintaining the optimal temperature in a fish tank is a crucial factor in providing a healthy and thriving aquatic environment. By understanding the specific temperature requirements of your fish species, you can ensure their well-being, growth, and reproductive success. Regular monitoring, investing in tropical fish tank for sale, and adjusting as needed will help create a stable and comfortable habitat for your aquatic companions. Remember, a well-maintained temperature is just one aspect of overall aquarium care, and providing clean water, proper filtration, and appropriate nutrition are equally important for the well-being of your fish.

they are also incompatible with each other. goldfish are coldwater. plecos are tropical. a common pleco can easily get to a foot in size, and "growing to fit the size of the tank" is a myth. a goldfish needs iirc 75 gallons at minimum for a fancy and common goldfish are better off in a pond. also goldfish produce so much waste. you need beefy filtration and frequent water changes to keep the water even remotely clean. and by frequent i mean at least weekly.

It's frustrating that so many people buy pet inverts without doing any kind of research about their care beforehand and they end up with a totally inappropriate habitat, diet, and/or general care.

Bugs are animals! If you're going to keep them, please learn about them from multiple sources before buying them. Reddit subs are an especially good source. Avoid pet store care sheets, as they are often deeply wrong.

Also depending on the species, initial setup can cost quite a bit, relatively speaking! If you can't afford an appropriate habitat, then you can't afford to keep the animal as a pet. It's not okay to give them an inappropriate or bare-bones setup because that's all you can afford. Save up and do it right from the get-go.

There's a lot of bad information out there on invert and exotic care, and we're always learning more. It's okay if you did do research, but you were given bad advice. Just be open to new and better information and make the necessary changes.

Thanks for coming to my rant :)
