On a side note don't let them get to hot, they are quite vulnerable to heat spikes a lot like most of the mantella species. I fiddled with them some in past years but found they really needed cooler temps than I could easily provide here in texas. They seemed a pretty tough and greedy little frog otherwise though. Stunning colors as well of course. I don't really suspect new breeding tactics are likely to be needed with this species, the same basic tactics that usually work on toads and other explosive breeders will induce amplexus and while I never got eggs I only had a small group and didn't fiddle with them for more than a year or so due to the problems with heat. Best of luck with them.
