I agree they are EVIL!!! If you have corals that you spot feed, they are the worst thing you could have in your tank! They will steal the food and even if you guard it for an hour and the coral has seemingly completely swallowed the food, they will dig in and rip out the food stressing and injuring the corals.
I had the sweetest aussie scolymia that they did this to and it never ate again and slowly died. Mine all died off from a redbug treatment and my aiptasia has been reintroduced to my tank but i will not put in peppermints again. As much as i hate them, i'm going with a copperbanded butterfly this time and see how he works.
