And I've not had this guy long...
Don't know the exact enviornment he came from.
Got him currently in a 55g (splicing/splitting it soon to around 30/25) for 2 habitats.
Have UTH on right and 75W heat lamp on top. Lamp runs on cycle (12 on 12 off) and UTH is left on. Have digital thermo..... at night (down time for lamp) ambient never drops below 75 (with thermo 1/2 way down the tank). During lamp cycle (with home AC wide-open) ambient stays around 85ish 1/2 way down tank) But UTH stays on the bottom and is directly under the hide. So floor temp should be around 89-90 on the floor
