I have seen that in Discus I was keeping. It is a direct result of bad water quality. Im sure you know that due to the parameters you posted. I treated with a bath of potassium permagnate.

alright. Thanks for the info... I hope this guy pulls through. Should any treatment be done to the main display tank?
