It depends. Are the frogs f1/ f2. how many adults did the person you bought them from have together. It doesn't really become to much of a problem until a few generations in with frogs when breeding them back. if they were from the same female and different males for example it wouldn't be a problem at all. I would say let them grow and look for signs of developmental issues first. I will post as soon as they settle when i get some licin. are you planning on getting some more broadleaf plants in their. Mine don't hang out on them to often but it would be goodd cover to make them feel more secure. A nice sized philodendron perhaps. Feel free to post any pictures as well in my thread. That's what its there for. Best of luck with them. They are incredible frogs for sure.
