Is true. But most Phyllomedusa Bicolor's available are taken right from the jungles in Suriname. So if you have the perfect setting they will thrive. The problem is taking them from the jungle and putting them in a controlled captive environment than they will lose their vigor (and a lot of them die at as well). Only one guy that I know of has mastered raising them in captivity and had many generations of them. He's the one you can find on youtube if you look up Phyllomedusa Bicolor who has the tadpoles coming out. I forget the name of the company. But better yet is the perfect environment with lots to climb and other creatures there too so they keep their defense peptides flowing. This is my theory/goal at least.
