I have never had a flame hawkfish but I did have a longnose hawkfish. I will echo Bob's sentiment, one of the best fish I have ever had and will definitely get another one if the price and specimen are right.

Behaviour is supposed to be the same; perching, curious, interesting fish. They do look very different, distinct body shapes. Mine could really swim, and jump. I rescued it off the floor once during a water change and found it dried up on the floor on its last day.
