To much moisture in enclosure and a question about heatpad

[John]

Secondly, a heat pad probably isn't needed at all. They do fine at room temp's assuming that it is 70's or warmer.

Perhaps in Texas, but Pacman frogs in my experience are rather cold sensitive and can develop health problems if exposed to temperatures below about 17 °C (63-65 °F). I would think that's more of a concern in Sweden.

Pacman frogs are south american tropical species. If I remember the come from argentine or peru or near there. Which in deed is constantly moist.

Different species of Ceratophrys come from different parts of South America. I must say I think it's rather funny to generalize two countries as "moist". Peru has a lot of rainforest but it has other habitat types with various climates, and Argentina definitely can't be summed up as "moist".
