wow you got niced crested geckos..but are they in a length tank or a tank that has more height? cause there arboreal but i was asking cause i was wondering if theyd do ok in a long tank rather than height..
I do not heat them at all, during the summer it stays from 74-78 in there and winter is 69-74. Sometimes on really hot days I will have to put buckets of ice in the room to keep it cool!
