Peppermint shrimp will not touch coral. There is at least one shrimp that looks similar to the P. Shr. it is a camel shrimp.with Aptasia-X I can't get to the ones that is under a rock or behind it. So eventually those that are left grew very big and was able to repopulate the tank full of aptasias.
TRUE peppermint shrimps did it for me too. I had 2, after all the aptasia are gone, one died due to starvation. So now I hand feed my other one with pellets, point is, true peppermints will not attack corals even when hungry.
right: Is the Camel shrimp
