Im really at a loss of what to do. I bought one of these (a pangasius catfish) about a year ago because well.. I wanted a big fish. I watched a few videos and saw they get about a foot or so in most setups so I figured I could deal with that. Well he was in a 29 gallon and while I was away someone in the house downgraded him to a 10 gallon so they could use the dresser space. He is now about 5 inches long but I know as soon as I put him in the 55 gallon I got hes going to get huge (hes grown about 2 inches in the last 3 months). Im a little worried hes going to eat the danios I have in the 55 at the moment as ive gotten quite attached to those curious little guys, so what should I do? I really don't want to get rid of him but... I may have to... to save my danios and for his sake. Next step is craigslist.. but I really don't want to risk sending him off to another cramped tank. Thanks for reading.
