I grabbed one of these guys from Big Al's last week. Wasn't sure how he would do in the tank (had bad luck with them not eating in the past). He took a couple of days to settle in, but I caught sight of him today and he is FAT. I didn't know if it would hit the substrate but he took to it pretty quick as well as hitting any algae he can find. Does not disturb any polyps or coral. I don't know if they have any left, but what a fabulous little fish. It even hides out in the star poly patch, just his little head sticking out. Not as much personality as the flame hawkfish (thanks to whomever suggested that as a good addition) but still, a fun fish.
