Yea, I was told by the Fishstore. He was a nice guy. He said he should be quite happy in a 20gal by himself. He was right. I named him oscar and he loves his tank, he's funny too. When he wants to eat, he splashes the top of the water. So I throw in atleast one feeder fish. I also read not to feed them flakes bescause they really don't get full off them. So I guess I'll have to feed him letteuce or something. I only feed him the feeder fish once a day, should I do it twice a day??Gunnie said:I think they are beautiful, but get very large, and I believe they are quite aggressive.
