Hey all. I've had this rabbit fish since May 2019. He looked like a normal spotted rabbit fish when I purchased him. When I brought him home and acclimated him he was dark almost black and his eyes look like they have cataracts. He has been that way for the last 2+ years. He eats well, sees fine and swims around with the other fish. I know they can change color instantly but to stay that way for over 2 years has me puzzled. About 8 months ago I decided to move him from the 180 gallon tank to a 150 housing a few tangs hoping he may go back to looking as he should. No such luck. He swims around with the tangs and eats fine. Shows no signs of stress just stays black with the cloudy blue eyes. Has anyone seen this or has any suggestions or do I just have a black rabbit fish rather than a spotted?
