@mwjust69, don't take this post up the wrong way.
It doesn't seem like you did any home work regarding this specimen. They are pretty easy to keep, but are fierce hunters. Problem here is, your clam, clowns, shrimps, and everything else small enough to fit into his mouth. At night when you go to bed when the aquarium lights are off, all those things are going to disappear.
Buying a fish small to resell when it outgrows your aquarium is just not right, it put uneccesary stress on the fish, never mind hurting it whilst trying to catch it.
Just a few things to consider next time.
