I got a beautiful tangerine from MM a few weeks ago, and am struggling to keep his terrarium warm enough.
I have a 20 gallon long tank with an 8 x 12 under tank heater that I have set to 90 degrees with the thermostat. The probe is set on top of the substrate (reptile carpet) near the gecko’s warm hide, so I think it gives a pretty good sense of the temperature.
For the first couple of weeks, it seemed to vacillate between 83 and 86 but lately it is struggling to get past 81. It has been really cold here, and the room temperature is about 68.
Other than cranking up the thermostat, what would you recommend for raising the temperature a bit? A lamp? A ceramic heater? Another heating pad on the side of the tank? All suggestions welcome!
