Can You Put a Flounder in a Fish Tank?

Yes, you can put a flounder in a fish tank. Not only is it possible, but it’s also recommended for people who are looking to add an interesting and unique species of fish to their tank. Flounders are fascinating creatures that provide plenty of visual interest with their unusual shape and coloration.

They need plenty of space in the aquarium to swim around – typically at least 20 gallons – and they should be provided with hiding places such as caves or rocks since they like to hide from other aggressive species. When adding them to your tank, make sure that the water temperature is between 72-78 degrees Fahrenheit and the pH levels stay between 7.5-8.2; if either one falls outside this range then your flounder may become sick or stressed out! Other than those specific requirements, though, these fish do not require too much special care and will reward you with hours of entertainment when kept properly in captivity!

What Size Tank for Freshwater Flounder?

When it comes to freshwater flounder, the size of tank you’ll need depends on a few factors. Generally speaking, adult freshwater flounders require at least 20 gallons of water per fish. So if you’re looking to keep two or more, it’s best to go with a 30-gallon aquarium or larger.

Additionally, these fish prefer tanks that are taller than they are wide since this provides more swimming area for them and allows them to move around freely without feeling confined. The tank should also be well-filtered as these fish produce quite a bit of waste and can quickly create an unhealthy environment in their home if not properly cared for. Lastly, make sure your tank is equipped with plenty of hiding spots so your flounder feels safe and secure while exploring its new underwater terrain!

Can Flounder Survive in Freshwater?

Yes, flounder can survive in freshwater! This is because flounder are highly adaptable fish that inhabit a wide variety of habitats. While most prefer saltwater, some species such as the European Flounder (Platichthys flesus) are able to live and thrive in both fresh and brackish waters.

In fact, this particular type of flounder has been found inhabiting rivers all across Europe. They also have an amazing ability to tolerate changes in salinity levels which makes them well-suited for living in estuarine environments where the water is constantly changing between being freshwater or saltwater depending on the tide. So if you’re looking for a fish that can survive and even thrive no matter what environment it’s placed into then look no further than your local river–because there may be a few European Flounders swimming around!

Are There Any Freshwater Flatfish?

Yes, there are a few species of freshwater flatfish found in the world’s temperate and tropical regions. These include the family of flounders known as Pleuronectidae, which includes both righteye and lefteye flounders. There is also the family of Pacific salmonid flounder (Platichthys stellatus) that inhabit coldwater habitats in North America’s western coast.

The African sharptooth catfish (Clarias gariepinus) is another type of freshwater flatfish that inhabits mainly shallow water bodies from West to East Africa. Lastly, there is the whitefin sole (Psettina punctata), a bottom-dwelling fish found primarily off Japan’s coasts but can sometimes be seen in inshore waters near estuaries or rivers. All these species have adapted to live entirely submerged on their “flat” side with both eyes situated on one side for better vision while swimming along the seafloor looking for food like worms and small crustaceans.

Although they may look awkward compared to other more common fish species, these unique adaptations allow them to hide away from predators quite effectively!



In conclusion, freshwater aquarium flounder are an interesting and unique fish that can make a fun addition to any tank. They may be shy at first but with the right environment they will show their true colors.
