i just went to the lfs and they had a some freshwater flounder. this was like 2 weeks ago so i picked one up when i saw it. has anyone ever herd of these and are they ease to take care of. i have ahd mine for like 2 weeks now and its still alive and i am not feeding it any type of food??????
 
They are a BRACKISH fish. They will require a specific gravity (SG) of 1.008 at least when they get older.

They eat meaty foods and grow 6-8 inches. They should be fed LIVE brine shrimp, frozen bloodworms (thawed, of course), and ghost shrimp. You should move the fish, return the fish, or change the water. However, if you change the water, you may not be able to keep your other fish alive.

PLEASE REALIZE THAT AQUARIUM SALT IS NOT THE SAME AS MARINE MIX SALT. THEY ARE TOTALLY DIFFERENT!!!
 
Actually I believe they're a freshwater fish when they're small and need brackish water when they're adults. Putting them in brackish water while they're juveniles is probably a good idea though. They also require a soft substrate like sand or they'll get injured.
 
this is not a sound post, period. why not feed it? at least try some different type of food. i suggest returning it.
 
As far as I knew, they are freshwater species, but you may very well be right in that they may grow into brackish.

That said, to the original poster, I suggest you do some serious research if you'd like to keep the fish. They require some special care and really need a sand substrate with lots of smooth rock and wood. They are also rather delicate to water chemistry, meds, and general parameters.

Also, I see no acceptable reason of why you have not been feeding the poor thing.
Feed it meaty foods like bloodworms, krill pieces, shrimp pellets or other similar foods, asap.

Research before you buy is key.
 
Nope, they aren't a freshwater species. While there IS a true freshwater flounder, it isn't in the aquatic trade as often the brackish flounder is.

If the flounder is over 2" it needs brackish water. Under 2", you can still keep it in freshwater for a while, but it will weaken and ultimately die if no action is taken.
 
How do you know thats not the kind he has? He didn't specify?

My appartment complex has a true freshwater flounder....
 
The true FW Amazonian flounder is quite rare in the trade and goes for $40 to >$80 at retail when it does come in. If that were the fish, I suspect the purchase price and rarity would have been mentioned. The fish in the trade are >>99% BW species, most often on the East Coast they are juvenile hogchokers.
