Nice longnose, hawkfishes are very underrated.
Sucks to hear that the clowns don't get hosted, but you never know. Maybe one day they will start to notice and then they'll never leave it!
I think you made a smart decision not to acquire a copperband for the tank, mine roams around tons to hunt. A beautiful and personable fish; it used to hide all the time but now it follows me everywhere to beg for food! My secret: live blackworms. No fish has resisted it since I got them a few weeks ago, and they all seem more lively and less shy now. If you want to try, I can give you a spoonful and see if your fish likes it.
