I have a Mandarin with 5 fairy wrasses, a Lineatus, Lubbocks, Pink Margin, Whipfin, and Solar with no problems in a 120 reef and 225lbs of live rock. I really don't see my fairies paying any attention to the rocks looking for pods, well I have never seen them go after pods on the rocks. Fairy wrasses are planktivores so the eat stuff in the water column. Also I have another 4 Fairies in my other tank and have never seen them eat pods off the rocks either.
