I've had this cichlid since the beginning of January, and for the first couple of months, he looked fine and was swimming around and finding his own little hiding spots. By the way, I switched from a 10 gal. to a 29 gal. about 3 weeks ago. It is only a blue gourami in with him and they seem to be getting along. But, whenever I look at the gaping hole in his head, I feel worried it's going to get deeper and deeper and soon become fatal. How do you get rid of this disease? Yes, I have done research, but it didnt help me much because they had a huge checklist and I had done all of the things on it. Please help him!
