Wondering if anyone can give insight on my guy's behavior. Warren G is a 12 yr old yellow lab cichlid. He has a cataract in one eye that's been there for about 2 yrs now. This morning, he completely flipped out when I came to turn on his light which is the same routine that he's had for the past 12 yrs. The poor guy spazzed out at the surface to the point where he splashed water out of the tank and onto the wall. He swam around breathing a tad harder than usual, but has been fine all day and ate normally. He's never acted like this - does this sound concerning or am I overreacting? Also, he lives alone!
