My little Flame Hawk is only about 2" long. Cute little dude with tons of personality. He'll come over to the end of the tank where you are, park his self and eyeball you. Then he'll double-clutch like he's getting ready to leave. Then just stare at you. He doesn't really bother any other fish. Likes to eat my smaller Emerald and Mithrax crabs. Cleaner Shrimp don't last too long either. He has to be the one gettin' em. Never see it, but they all disappear. I'm thinking of trying a Scooter Blenny, small one and a Court Jester Goby. Get the Tang and the Bi-Color Chromis out and maybe add a Fathead Anthias or a nice pair Firefish ??? I tried a One-Spot Foxface. Worked out great at first, then he started eating corals.
