My lfs is selling baby warm water White Sturgeons about 3 1/2in. long, and I'm considering buying one except im not sure if it would be compatible in my tank. Mainly the only thing im worried about is my 12in. Marble Catfish, I already feed it feeder goldfish that are about 2in. and nightcrawlers about 6in. long and I'm worried it might just feel like going up a size in food. What do you think?
