I would LOVE to breed any of the dwarf cories. I've kept both Hastatus and Habrosus and I love them. They were kept in community tanks, and they never showed the slightest signs of wanting to breed. Would a species-only tank be a better bet? Would cherry shrimp be an issue with the eggs?
Pygmy Sunfish, darios and badis are good choices but I think they require live foods all the time? I don't mind feeding live foods to get them in breeding condition, but I'd prefer not to keep fish that would always require it. Am I incorrect on this assumption?
