Eastern Gray resting under water

[RLDSL]

we have ( what at best guess are ) 12 eastern grays that are about 2 years old now that we raised from tadpoles ( we rescued the tadpoles from an empty jacuzzi that was about to evaporate during a drought so we aren"t 100% positive as to their breed , but considering the wild origin....), and they live in a rather large enclosure with a nice little area to splash around in, and the other day we came home with some crickets and found one laying motionless on the bottom under water and assumed the worst. I went and got a net to fish him out and when I touched him, he got startled and jumped out! Most of the other frogs were dipping in the pool and a lot of he'n and she'n croaking going on.
He got out and hopped around for a day and as decided to find his way back into the water, but has not gone belly up, he's just laying there on the bottom, not looking at all strange.. Now we keep the house fairly cold and the water end is close to a glass door and the kids forgot to turn their heat lamp on a couple of times at night . Is it possible this is some kind of hibernation behavior ?
Thanks
