I have a 20 gallon long tank with my 6 month old male. I weighed him tonight and he is at 276 g. He was 215 when I got him on Nov. 10 (hatched in July). My setup consist of 2 UTH's that cover a majority of the bottom of the tank. The glass surface on the cool side of the tank is at 80 and the floor surface on the hot side is between 88-90 depending on where I shoot it with my temp gun. The first month and a half I had him I did not have any other heat because several people have told me with the surface temps being 80 or higher throughout the entire tank and with the ambient temps in that room at 70 degrees the temps would be fine. Others have told me I still need the ambient air temps in the tank warmer even if the floor temps are warmer. I added a small CHE last week and now the ambient temps are showing 78 degrees but my humidity has taken a big hit. I am spraying several times a day and it will go up to 70 but 4-5 hours later it will be back down to 45. Tonight I added some moist sphagnum moss inside each hide and while doing so I noticed his eyes are blue so we are getting ready for the first shed since I have had him. Would it be better to turn off the CHE for the next couple days until he sheds and get the humidity up higher? The last day or two I have not seen him leave his hot hide so I assume at this point the humidity would be more important then the higher ambient temps. I know both being perfect is ideal. I have about 90% of the tank covered with plexi glass and before adding the CHE I had no problems keeping humidity up. I am using forest floor for substrate.
I've received feedback from multiple people on here, some saying the humidity is not as important as the temps and just keep the temps up and others have told me that since my floor surface temps are all above 80 that ambient temps are not as important as the humidity.
