I got a Mimic Goby (blue head, yellow body, dark blue strip down the body) when I was at Fin-Addict a couple of weeks ago, and he/she has gotten so fat it looks like its about to explode. I mean it has gotten a really, really fat belly. It seems to be eating fine, and does mostly what Gobies do, which is just hanging out.
Is anything wrong with it?
I lost a Powder Blue Tang in this tank a few days ago, so I'm a little antsy right now.
