I am currently building a new vivarium for my Phelsuma Klemmeri. I am wondering which is better, A rock heater controlled with a timer and rheostat, or just a basic heat lamp? I would like and appreciate any suggestions. My concerns about the rock heater is the humidity levels that the Klemmeri seem to require. My concerns about the heat lamp are the basic lack of controls on heat. I am building a 34g Exo-Terra 18x18x24 tank which will have a water feature as well as full spectrum fluorescent lighting. It will also incorporate a ledge up higher as a basking place as well. There will be a fan for added heat control as well as a number of potho's plans and various moss's etc. Thanks for all your advice in advance.:biggrin:
