Thanks guys,
Little Red is currently in the 10 gal with the two micros, one of which is dug under. He seems to be doing well so far, I've seen him drinking and he has been eating quite a bit! So hopefully everything will be fine.
Actually, I'm suprised that he was the only one that showed signs of stress from the move. I had to dig up three crabs of the seven to transfer them into a smaller tank. Oh, and that week that I drove from Texas to Idoha, there was this huge cold front, and going through Colorado it was snowing!
I'm just glad the rest are OK, and thank you guys again for the good advice.
