Okay, thanks, BUT...he's being stubborn. He grazes on the bottom, and since my cleaning crew it all of 2-4 crabs (?) and two lazy snails and an arrow crab, he is probably finding plenty to eat. I don't know though. He seems to nibble at the rock, but he refuses the sea weed, the dried algae and the mysis. Any idea's? Maybe just let him get used to things? He's new. He seems in good health. (None of the fish really seem to like to garlic stuff I soak the mysis in, the seems to like it better without, especially the puffer...is this unusual, or is it maybe a bad brand?
