I was thinking of setting up a few old 55s and 70s into frog habitats. I like both but I never kept frogs being a snake and lizerd guy. I think it would be kewl for the kids to see the would stages of frog life. How hard are they to breed? How do you tell male from female? How come no one sells proven breeders? Plus I feel that my kids would have fun keeping them and selling off babys to petstores. We breed boas but I think it would be kewl to jump into frogs
