To all aldabra owners/keepers I would like to ask a general question regarding low temperatures. We have always been very strict regarding the low temperatures, anything below 55f we heard ours in to heated small barnes. I know that some zoos have a low of 50f. Can everyone that keeps this species, or anyone with good knowledge of this species please provide an opinion for what they feel or have experienced is a safe low teperature. We have always never had an issue at 55f, keep in mind ours are way mature and aclimated adults. Of course the young aldabra holdbacks are at a much higher temperature. All hatchlings are kept at least 70f and yearlings+ are kept at 65f. This has always worked for us, never having any medical issues. Thank you all. Greg.
