I think Firefish are one of the most beautiful fish. Until you own one you don't know about the yellow and purple on their heads because it never comes through in pictures. And the redish orangish flowing tail catches the light in gorgeous ways. They are VERY timid though. If the lights are off, mine is in his cave. He literally never comes out until the lights go on, and the second they go off he darts back in. And while the lights are on, he spends all his time swimming away from any fish that comes anywhere near him. EXCEPT my possum wrasse, who is everyone's best friend.
