How big do they usually get in tanks? I can't seem to find any solid information on them. The best I've found suggest 2 feet in the wild though I'm not sure what that translates to in a tank.
Btw, I recently just found out I had a Sleeper Goby heh, which I know, I should've done the research first to make sure. It was sold to me as a "Jade" Goby though I assumed regardless it'd be fine because it would be going into a 120 gallon tank with some catfish.
Right now it's probably 7+" long, he's a fat fish and is the master of the tank. He even swims up to the surface to piss off the 7" Marbled Characin I have. Now that I read though of how big he gets I'm probably going to give away the "Gar" and a couple catfish.
