SO today I decided to go to my LFS to find a new bottom feeder for my 33gallon angel fish tank. I wanted some clownfish loaches but then decided against them given their adult size... I then looked at some panda cories (which I ended up getting two of).. and as I was walking out I saw these adorable little flounders living in a regular tank with regular gravel and gouramis. I had never seen them before and was totally in love with them. The people at the store have always been knowledgeable about the fish so I decided (against my best judgment) to listen to their advice. I was told that the flounder would do fine in 75-80 degree water and would have no issues with my angels. I asked everything I could think of only to find out once I got home that the flounder prefers brackish water, thinner sand, and is a carnivore! I will go to the store immediately tomorrow morning to buy bloodworms for it.... What else can I do to make it happy in my tank? Would it be advisable to return him? I don't want to make the fish suffer unnecessarily and I want to give it a good home. Right now it's just swimming around the water and close to the air bubbles instead of being at the bottom. The panda's are just swimming all over the place, but I read that is supposed to be normal. Any feedback would be of great help. I have never had much luck with bottom feeders!
