You are one very luck reefer. Hobbist pay over $75 buck for those little guys over here. I've been on a waiting list for over 4 months.
No he is not good in a reef tank. He will eat your inverts. and your smaller fish. He may mess with your corals.
If you have an extra, small tank handy. a 15 or 20 gal will do. Set it up. All he needs is some rock. Feed him meaty foods. Silverside, bloodworms ect.
WARNING: Watch your fingers, They can slice you open!!!
You are so lucky. He is a beauty. If you don't want him, how close are you to St Louis.
