Hi Cepuras. I'm glad to hear your black belt cichlid is better. That's great news. :) It might be hard to get him a friend though, even a female. You'd have to make sure it was definitely a female and watch for aggression. But baby black belts sure would be cute. :)
A few weeks ago you gave me some help in identifying a sick fish.. The black belt cichlid.. I'm happy to report that after the treatment you recommended he seems to be doing better. He's still a bully, but swimming around the tank, and even eating, which is unbelievable.. Strangely i've tried feeding him all sorts of dry pellets, frozen foods, and the only food that he'll eat are earthworms!? A bit strange.. I Think you may be right that it's a male..? Wuld be nice to find a female for him, or any kind of a compatible tank mate.. He's mean.. All the best!
