Leopards aren't too bad provided they:
1) Don't injure their mouths. This often happens in shipping when they dive bomb the bottom of the shipping container trying to bury themselves. A damaged mouth for these guys is pretty much a death sentence.
2) Have a sand bed for them to bury themselves. This is in no way optional. Many times they end up in a wholesaler's or retailer's bare-bottom tank and they stress out or injure themselves as above.
3) Get eating. They seem to like smaller foods relative to their body size.
I think yours is going to do well!
I have a meleagris now and am considering picking up an ornatus. The meleagris is my largest fish with the exception of my tomini tang, and pretty well is ignored and hasn't harassed a thing.
