These are relatively new to my collection and haven't produced any offspring yet. If they are like other Ranitomeya species the females can produce a clutch of at least a few eggs every couple of weeks on average.
I've heard they do great in equal or Male heavy groups. I bought 4 from a private breeder, ended up 4.0 What I original confused with courting quickly turned to combat. Now I have 2.0 :-( thinking of buying a proven or probable female or 2 this year.
Wow, bad luck. I definitely lucked out with a 2.2 group. I have seen some intermittent male/male aggression but the females seem to get along. I'm hoping once they are in their larger permanent vivarium they will have plenty of room to establish their own territories.
