Hello, my deffinitely 10 , maybe 11 year old female convict cichlid is my first serious fish I ever owned, she has seen many fish come and go and has defended herself against some beasts in the passed. She has had many fry with a few different fish over the years but most recently she proved a theory wrong with her viable young when she partnered with a male red Ceibal that I own. The last month she has slowed down a lot and was using plants to keep herself stationary, but she was eating normally at feeding times and still do. I went away for couple days and when I cam home she was gone so I looked around the tank and found her jammed behind driftwood, I assume to stay out of the way of the other fish in the tank, her fin is down the "boney" parts close to her stomach and the other is starting to turn white, under her jaw she also has a patch that looks like decay and not a wound. Her right eye is also glazed over white but was for a week or two now. I am wondering because it has taken place very slowly over month or two is it natural way of her slowing down before she dies or is this something I can seperate her and treat her for. The fish in my tank seem to have never been more healthy and everybody is feeding normally if not more then usually, even the plants in my tank are growing better lately. I don't want to sit and watch this happen but while she was still feeding in wasn't this worried until now.
