I was at my LFS yesterday and saw they had a flounder in a freshwater tank. It was 2 by 2 inches. On the tank description it said it would eat algae. This shop has no saltwater tanks so it must have been freshwater. Just wondering if anyone ever heard of a freshwater flounder before. I was thinking of picking it up if it stays small and is indeed a freshwater fish. Any info would be appreciated.

There's a "freshwater flounder" you see for sale a lot that's actually a brackish fish. It can survive in freshwater, but it doesn't do all that well in it from what I've read.

Thank you very much. Do you know how big they get? I might set up a small brackish tank for the flounder and some bumblebee gobies if it remains small. The last thing I want is a 20" or bigger flounder.

Agreed, flounders sold as freshwater are usually brackish, gets to about 6", and doesn't eat algae. There are true freshwater flounders, though you'll rarely see those being sold.

I have had 2 freshwater flounder for almost 2 years. I keep them in my community tank (freshwater), and they do just fine. I got them at about 3/4" and they are now a little over 2" each. I don't know if they eat algae, but mine are constantly pressed up against the glass, so maybe they do. All my "non " fishy friends think they are pretty cool. Good luck.

no such thing as a FW flounder. i made the mistake of buying one. they dont eat algae and they need brakish water. mine eventually died because it would not eat any food that i offered it.
