Cohabitation
Pair or small group. Unlike most poison frogs, this species also tolerates being kept in larger numbers: keepers report three males with one female without aggression. The males call to each other and thereby stake out their territories without fighting. What's needed is a floor area on which each male can find its own calling perch, plus dense leaf litter and several hiding spots. Freshly morphed juveniles are raised separately, because otherwise they lose out in the competition for tiny feeder insects.

Notes

A leaf-litter ground dweller, less fond of climbing than Ranitomeya.
