I have a baby ornate horned frog in an exo terra 18"x18"x12" set up with a zoo med 10-20 gallon UTH mounted to the side of the terrarium and a 60w zoo med daylight bulb on a dimmer at the top of the terrarium. I've been switching between that bulb and a 60w red heat bulb. Even with both the UTH and light the temp during the day only gets to 80 degrees and 75 at night. My question is, should I get rid of the light and replace the current UTH with a 30 gallon one? So that all I will have for hear is the 30 gallon UTH. Btw I have the UTH connected to my hygrotherm with it set at 84 but it never reaches that temp.
