Thanks!! He's about 7-7.5 inches. I don't have a digital scale but he is HEAVY!!!

Last night I went down to turn off lights and feed the Horned frogs. I noticed my pyxie was in the same spot/position as a few hours before in his water. His eyes were closed. I opened the glass and bumped him...no reaction...I flipped out thinking he was dead. I scooped him up and he started moving and I put him on the land area. I tried to feed him and he wouldn't take (he has NEVER turned down a meal). I let him sit for a couple minutes and tried again. He ate. What was going on here? Was he sleeping in the water? It scared the **** outta me.
