I named my sulcata Ki(don't know what "his" sex is yet) and my two crested geckos one is probable male, named Kael, and the other is hopefully female because I named her Isabo
I named my Sulcata Lug Nut my CDT is named Grapes (even though she's not allowed to have them) and my eastern box is named Munch. My buddy named his eastern box Cheese. I usually pick a name I like saying or that fits the animal.
