I am used to my cichlids beating up on each other from time to time, and bite marks always heal up within a few days...no big deal.
This fish was wounded about a week ago, and it seems like the bite wound has just gotten worse and maybe has progressed into an ulceration.
Do I need to treat him in a hospital? I would prefer not to since reintroduction into the cichild tank can be rough, and risking him getting beat up even worse after the treatment. But, if he needs to be put in a hospital to save his life, I will do it.
Please let me know what you think! Thanks!
