I think I had read in another thread someone saying that their peppermints were snacking either on their Hammers or Frogspawn. And a big discussion as to whether they are actually peppermints vs Camel shrimp.
Last night I flipped the lights on in my basement after all was dark and saw one of my peppermints snacking on my octospawn. No significant damage that I can tell but I took it out and put it in my frag tank. Seem's fine today.
My tank has been free of visible Aptasia since buying the peppermints and I have checked the stripe pattern against what camel shrimp look like and they are peppermints. (Plus I got them from a local reputible source

)
It aggravated me a bit as I really like this octospawn in the display but hey what are you going to do, I am not going to catch the shrimp and struggle with aptasia again...
