My frog isn't moving

[GRABibus]

Ok.

Mine is kept at 26,5°C at day, and between 21°C and 24°C at night : 24°C in summer due to my appartment heat and 21°c during winter.

As you can see, there is not more than 6°C between night and day.

Now, my frog is burried since one month, so it hibernates.
I dropped down the day temp to 24,5°C and the night to 21,5°c (With Lucky Reptile TCP2).
I let the substrate dry.

Your Pac has been sleeping for a month? With normal temps? Do you check on it? They don't hibernate unless conditions are right. Normal temps are not the correct conditions for hibernation. Farely dry soil is but temps and humidity levels are usually a lot lower. That's what puts them into hibernation mode.

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.

I have heard of this. The bad thing is under normal conditions is that they can have normal metabolism and possibly die. They have to be really fattened up before being allowed to hibernate. Usually you hibernate them by reducing climate conditions 2 degrees per day and the samewith humidity and moisture over a period of 2 weeks. Odd that they go under without having reduced climate. Could be pressure change but I don't like that without proper conditions for hibernation.
