Try the bath, or laundry tub, fish bucket, chilli-bin...with a bit of water. Or even dry dock it. Put in a box with sides so it cant climb out and cover turtle in a towel to help calm it...tho this is only OK for a short time. Also need to transport it dry. Never in water, as all that swishing water can cause aspiration pneumonia.
I pmed you some more info as well...we are crossing posts :lol:
It will likely climb out the 1 ft high tank....unless you put a lid on it, that it cant push off. That tank would be OK as an emergency holding area, just dont let it sit in sun and get overheated and as said, cover with something heavyish
