He is in a rock cave at the top of the tank.
The shell is about 3" long
He has been in the tank for a week.
This is probably my most irresponsible purchase so far. I do have hermit crabs and some emerald crabs that may end up bothering him. They usually go for anything with sponge growing on it, and there is no life in the cave other than the scallop. There is flow through the cave so he is getting phyto.
If he dies, I will cook him for Jerry for supper..mmmmm.....Joking!...Yuck....ewww.....
