Oh I just realized we didn't welcome you here yet!

welcome to the forums!

temps you need to jeep your pet need to be similar to those in a wild, in Pacman frog case it is wgat I said earlier, it can be slightly higher or lower, for babies you can go to 84 during a day, the numbers i stated earlier are happy safe medium that you should be aiming. Prolonged keeping in low temps will lead to seriuos heath problems.
60w is ok, provided you have a dimmer. I use 50-60 too.
the best is to get infrared lamp and use it with a dimmer, you can use it all day and night to keep temps where they need to.
but it would be even better if you could get hydrotherm by zoomed, plug your fogger, infrared lamp and your UTH you have. That thing will keep humidity and temp spot on day and night.
You can use ceramic heater too.


Based on your pics you need to increase your humidity, tank looks too big, but very nice! Frog is little cutie too.

Let's see how it will go after you fix humidity and temps, please update us.
