Yes, it is burried since one month, with normal conditions.

Be informed that all the frogs of my friends (Keeping in the same conditions) have burried for weeks starting at the same period.
It is common that pacman frogs burry starting november, december to hibernate, even with normal conditions.

I think they feel the decrease of climate pression outside, even if there are "Hot and wet conditions" in the terrarium.

All people I know on french forum have for 80% their frogs burried since November.
