They are really more shy when I come around. If I stay far away they don't seem to care. As soon as I get close they swim back under some rocks. What I have actually started doing is I kind of low crawl to the tank to feed and they have been staying out a little more. I have a 90 gallon with, yellow tang, kole tang, paired maroon clowns, 6 line, and a rusty wrasse, brown benny, diamond goby, some cleaner shrimp, and peppermints, snails and blue leg hermits. none of the fish have been aggressive towards them
