Cohabitation
Group (5–10 animals). Raise juveniles separately from adults. Not because they would be eaten — these animals are far too small for that — but because the larger ones get to the food first and the smaller ones fall behind. Provide enough hiding places so that every animal can retreat, and feed separately if there is a size difference.

Notes

From drier forests than the other Mantella species – it takes a little less humidity, but needs a clear dry phase to stimulate breeding.
