I have a strange question for all of the dart frog owners and breeders.

I found a local breeder with dart and thumbnail tadpoles, and it got me thinking. If I were to buy a pair of froglets (from the same clutch) a few months OOW, and they mature into a male and female adults(brother and sister), then happen to breed. Is that a "bad" thing? I'm sure its not good.

Does amphibian inbreeding cause defects like in other animal species?

Its something I hadn't thought about while looking for frogs. I'm not interested in breeding them on purpose, but if nature were to work its magic, and I get inbred tadpoles. Will I end up with two-headed, six legged froglets?

I'm curious to see what the overall opinion on this would be
