If the frogs are near maturity, then I strongly advise not doing so. True, they are the same species, but they are different morphs. 99.9999% of us froggers are strongly against hybrids and crossing morphs is no exception. Keeping them together as froglets/jvl's is fine if the tank size meets their comfort level and there isn't any food competition (which is a very common problem). Hope this helps.
