My beautiful betta fish, Jesus, is very ill and I do not know what to do. I got Jesus back in June of 2015, he had a 10 gal
tank to himself till November ish. I noticed Jesus wasn't feeling well, sitting at the bottom of the tank, not swimming, not fanned out, faded in color, not eating, white bubble over eye. I changed my water completely thinking it was a bacterial problem, but I feel that was a mistake. I also temporarily kept Jesus in a small tank to help and fight of the disease. I love this fish so much, I want to heal him, please help.
