Hello. I've been lurking for a while and have learned a lot. I finally have a question that I can't find the answer for and would like some help.
One of my otos has white spots and I'm not sure what they are. It may be ich but I haven't introduced any new fish to the tank is several weeks. None of my other otos or fish are showing any abnormal spots. If you have any ideas what it is let me know.
