I have a pair of Taeniacara candidi that I really want to breed and they're ready. The thing is the female is the boss in this setup and doesn't let the male get close to her for a long period without chasing him off. He looks tired and is missing a little chunk of his tail fin. What do I do to calm them down and hopefully induce them to breed. The water is soft, could be softer. I introduced a group of ember tetras to dispel aggression, and I'm going to add a mated pair of Laetacara curviceps to the mix as well. Any recommendations?
