tube anenome help needed

[bubbas929]

ok, so i got this tube anenome earlier in the week. i went out for a couple days and my wife said it was trying to get out of the bowl he is in and this morning it came all the way back in. so i came home and he is not opened up, more of a closed looking flower. i pick the bowl up to see what is going on and the tube is seperated from the "foot"!!!
is he dead? what happened?

now he is seperated from the big ball of stuff and the tube and flower are outside of the bowl.
should i put it back or let it be?
ANYBODY??

Why do you have this animal in a bowl?

 

[bubbas929]

because the LFS store had it and told me they do not move around and i read it here that they need a substrate floor of at least 4 inches.
is that wrong?
