I have 1 stone catfish in a 2.5gal with a betta and some molly fry. The tempature is on 80f because my betta was half eaten by my crayfish (I put him in with my blue gourami and I forgot I had a crayfish in there as well ) Anyway, he's doing well. He grew all the body that was missing back and starting to regrow the tail. There is aquarium salt in there as well. The molly fry are in there because all the rest of my tanks have either midas's, green terrors, convicts, kissing gouramis and the crayfish. Plus those tanks are so big they would get lost. I have the stone catfish in there for the same reason. Right now he is about .5 of an inch long. I give the fry crushed tropical flakes 5 times a day, the betta gets betta food once a day, and the stone cat fish eats what ever is left from the other fishes food plus I throw in a tiny bit of algae wafer. I heard that stone catfish are pretty hardy and they eaten flake food, frozen food, and the wafers. I also read that they get to be 6 inches long, is that true? If it is then I'll get another tank for him. I really like him and want to get another but I won't do that till I can get something else up for the fry. Is there anything else I should know about these guys?
