I have been looking at tortoises and I have chosen a tortoise that I like, the greek tortoise. Do you guys like this tortoise? I understand it stays somewhat small and is hardy (is this true?) There are just a few possible problems... 1. I live in cold new jersey. I understand i will need a heat lamp and uvb bulb, where can i get these relativley cheap? Second I only have room for a 4 foot X 3 foot setup, is this big enough? Thanks!
