Question for the Tang keepers

Will my new little white calvus (a little less than 2 inches, nose to tail) eat my new little hequi (about 3/4 to one inch) if I put them in a small tank together, with a shell bed on one end and a rock pile on the other?

I think they will be fine. Adult calvus eat tiny fry but don't bother small juvies ime. They don't bully other fish much either but they can be pretty rough on each other.

OK, cool.
Right now they are in a 5.5 gallon, and I need it for my new "wet pet" , Stumpy.
Stumpy is an awesome colored male demasoni, that sort of er...got his entire tail
bitten off. He has been living in the "time out box" and has gotten so spoiled he
lets me hand feed him. It's funny, he swims pretty good with no tail, but the way he moves his body while swimming is the same body movement the clown fish in the
salt tank makes. I have no idea if the fin will grow back if entirely removed, does any
body know?

I had an auratus who had the tail completely bitten off into the body and it did eventually grow back. It looked like it was a little smaller than what was normal, but it worked fine.

If it´s only the fin that has been bitten off and there is no damage to the caudal peduncle then it will grow back.
