He is a jade golby I have had him about 5 months. He is 5-6in long. I think he is blind because he constantly swims into things like the stone cave that's in there. He swims right into it several times till he finds the entrance. He swims into the heater, the filter, glass walls, goes for food and always misses on the first shoot. The other fish started picking on him some so be stays on his side mainly. I spoke to the store they said maybe it was some cloudy eye thing and fave me stuff to treat. Didn't work. I don't think it's a disease . None if my other fish have a problem and he has done it since I got him. He is starting to lose a bit of weight because he doesn't get as much food cause he misses and the other fish get more. I try and make sure he gets enough but it's hard. Any suggestions? If things don't get better I gonna have to find him a home. I don have another tank big enough for him. He should be alone so he can have more food. But finding someone to take him is t easy! I don't trust just anyone!
