That's funny, i was actually seriously thinking about setting up a breeding tank for them today. It sounds like they're pretty easy to breed. I also have Centromochlus reticulatus, which i call "devilcombs" since they're more black than honeycombs. I think i would probably try breeding them too since they're very rare. Hmmm... problem is i don't know how many males/females i have of the C. reticulatus. I don't think you can sex them the same way as honeycombs.
