I was reading in the forum and someone mentioned you had luck with a sick angelfish. Our 55 aquarium is about 4 months old. We have 5 angels, 2 gourami,2 cory cats, 1 pleco, 2 pictus cats. A week ago we lost 1 Angel which got really bloated and wouldn't eat.(Not even the peas) 2 days ago our other big angel strarted breathing really fast at the top of the water and he won't eat. Today his gills are red. He also got a hole at the top of his body and it is getting bigger. Any idea what that could be? We somehow got an ICH problem at the same time the 1 angel died and treated the tank for that. The ich looks to be cleared up. All the water readings are ok according to the charts. I don't know what could have happened all of a sudden. About 2 months ago our ammonia levels got high, but we got it under control in about a week. Any advice would be greatly appreciated. I don't want to loose any more fish.
