while cleanin' the tank the other day I noticed my peacock eels eyes seemed glazed if viewed from a funny angle. I didn't think anything of it at first, thinkin maybe it was just the dim light in the room. Watching it today it swims around the top of the tank or just floats slightly vertically. The ph levels and everythin' seem fine in my tank accordin' to my kit, but I am goin' to go get it double checked by the local pet store tomorrow. The other fish in the tank seem fine, I even have another eel in the tank who's eyes are crystal clear and he seems fine an active. What does my sick one have?And how can I remedy it?
