My own immediate experience pertains to M. Betsileo specifically but having buried myself in a fair bit of research as of late I have to say that they have captured and occupied my attention in a significant fashion. I have already observed numerous behaviours and habits while I study my growing colony (x6). I hope to become experienced enough that in the near future I can attempt to breed the more endangered mantellas that are out there to help cull the wild caught related pet industry and better support the captive breeding community that is trying to flourish. Being in Canada my exposure and access to certain mantella lines is closed off or fairly restrictive as most if not all U.S. related breeders don't seem to ship to this country.
