My BangaiI Cardinal has a large bump that started off looking like a small pimple on his left side. He has another smaller one on his right. No one seems to know what this is but I've seen a couple other threads about it but no answers. He is still eating, in fact, it seems that he's eating more than usual but that could just be that there is something in the vitamins that I've been giving him since it came about. If you know anything about this please, please reply. If I find out anything I will post it on here so people who have this problem in the future will know how to treat it.
