I have a single fire goby and over the last month or so it hase gone crazy. I have noticed on ten or so different occasions after a feeding of flakes the fish will dart around the tank with no regard for its own head, bashing into the glass and actually knocking itself out. It will then come around and act like nothing has happened. The occasions are becoming more frequent and the most recent found the fish out of the tank and on the ground. Lucky I was there. Is the fish have a reactive seizure from eating. Anyone who has had this problem or knows what's going on please help. Should I be planning a fish Funeral?
