Hey guys, I have never used a heat mat with a reptile but from what I have heard from alot of you it is the best thing to use with the bloods. My borneo is in a 40 gallon critter cage. I know you like the tubs better but this is all I have to work with right now..lol...My question is would I need a heat mat on both sides of the tank? Would it be better to connect them to a thermostat or a rheostat to control the temps and what temp should I keep them at so I don't burn her? She always stays burried so she is constantly on the glass. I found a ZooMed Reti Temp 500r thermostat and a Repti Temp Rheostat. Sorry for all the questions I just want to make sure Im giving her the best I can and Im hoping by switching to this heat source I can keep her humidity up better and a constant steady temp. Thanks for all the advice I have gotten. You all have been a great help.
