Sucks about the nose, but he's gorgeous. As you already know they are capable of growing to more than 40" in captivity. Try feeding him shrimp if he'll take it. Hopefully that bent nose won't deter him. I wanted that fish myself but didn't have the asking price for it. Would look really nice in the 3000 gal I am building though lol. Good luck with it. Keep an eye out for infection around the broken area. Not much you can really do unless you have a surgical tank setup to do surgeries on fish. Put him in some sedative, run ariated water through his gills while he's out, bend snout straight and use stainless steel bracket to hold it while it heals. lol, jk.
