Oh, they ARE addicting! It didn't start with a BP though with me. My first Reptile was my Leopard Gecko, Gaia, and since her I've fallen hard for Reptiles but for Geckos mostly. I am planning on having a small rack (5 tubs maybe) for BPs though, but that'll probably end up expanding into more with all of the morphs I've fallen in love with, lol.
The only reason I only have 1 BP so far is because I don't have the money right now to get the morphs I want!
