I'll try and find out what he's been feeding it, this is the only fish he has ever kept but I still don't see that as an excuse, before I kept fish I would've known that this fish is far too big for this tank, it can't even turn! I guess some people just don't care.. Is it likely to get any bigger at all if moved into a larger tank? Wish I knew someone with a tank large enough for it because the 260 i've ordered wouldn't even hold this fish for long if it started to grow again..
