This is my gecko male icy he is a 3 yr old Mack snow and is going to be breeding his lady soon she is a super snow I'm just getting back into the trade so I'm starting out small hopefully picking up a giant soon the second picture is of his current house which I hope to have a colony of snows and Mack's and supers in and just produce various snow morphs from him it's a 4 foot cage which is huge for him but be is doing good it is heated by a ceramic heat emitter that keeps it around 85 in there
I would also use a probe thermometer to more precisely measure the floor temps , which should be around 90-92 on the warm side. Check out the housing section as you might want to update your knowledge if you have not had geckos in a while
