How can you clearly distnguish between Mantella Ebenaui & Mantella Betsileo? I read somewhere recently that some M.E. have no back patterns while some do and the same for M.B. Are they in the same family but a different color/pattern morph? When I show people photos of my Mantellas I have a larger majority tell me that they are M.B. (my research confirms the likelihood that they are) but a slightly smaller fraction of folks tell me that they are M.E. I ask as I want to ensure that any new members I add to the habitat are compatible.
