So I've had this Orange Spotted Goby for about two weeks now, bought from LiveAquaria. It has been acting weird since day one. Randomly throughout the day it will starting freaking out spinning in circles, then it'll swim vertically and upside down. Sometimes it'll even let itself get carried around by the current getting bumped into rocks or whatever gets in its way. Then it'll stop and be fine. The first night it did this I thought it would be dead by morning, but it was just sitting there in the morning. One other thing is I can't say I've ever seen it eat, but it must be to survive this long right? I've searched for any clues on what's going on, but couldn't find anything. Any ideas?
