Hey i was wondering if it would be a good idea to get two baby RETFs right off the bat of being a new owner to them. i've never owned RETFs, but I have owned Fire bellied toads and a leopard gecko. SO should i get one or two or does it not really matter. I was wondering as well if it's okay to keep two or one baby RETFs in a 18 x 18 x 24 Exo Terra?
