From the research I've been doing it seems that the Peruvian Boa are some of the biggest boas in the world. I love the Peruvian because of their bright red tails. Seeing as how big the Peruvian boas get is it a bad idea to under feed them to grow them slowly? For example instead of offering a boa a large rat every two weeks maybe switching to a medium rat every two weeks. I'm new to the hobby and I'm looking to some of you who are more experienced owning boas.
