Hi, I have had a black moor goldfish for about 5-6 months now. He has had a swim bladder disease for about 4 months now and seems to be permanently stuck upside down But that isn't the problem anymore. Lately he has had a red ring around his on fin on his belly and a strand of white stuff hanging from the end. Now last week he has gotten a red "bruise" it looks like on his belly near the fin. He can still swim and will occasionally swim to the bottom if he has a lot of energy. He was in a 20 gallon tank (yes, i cycled it) with another black moor and a ryukin goldfish (not the best match) and another little guy, not sure what name though, rather small. I have now put him in a 1 gallon tank so he wont possibly "infect" the other ones and do water changes as much as possible (at least daily). This is just a youtube video my brother made before the red bruise and white strands. Hope I will get some answers
