Some things eating my zoa?

Alright so I've just noticed something or someone is snacking on my zoas outer skirt! I only see it on one as far as things in my tank I have a coral banded shrimp, fire shrimp, cleaner shrimp and peppermints with snails and hermits, but I'm not sure if it's one if those guys or something else, help!! If u need a pic I can get one up just let me know

 

My vote goes for peppermints, after you have ruled out nudibranchs, asternia starfish, sundial snails.

 

They eat zoas?? that i wasnt aware of, im not sure if i have any asternia's or sundials, ive never heard of them so ill do some research on them, i know i have some small star fish, and a few random snails that ive been seeing only at night, so ill keep you updated!

 

Peppermints have the potential to eat just about anything, as does any other crustacean. Especially if it's not a peppermint, but a camel shrimp, which looks pretty similar if you're not aware of the difference.

 

Ok, i do have the starfish, not many but i was told they were ok to keep in a tank b/c they are reef safe? is this not so?

 

no they are peppermint shrimp, im 100% sure on that, the LFS i got them from had both in the same tank and i picked them out myself, and they were peppermints, i do have the star fish talked about should i pull them out if i see them? or are they ok?

 

My asternia ate my zoanthids, this I know because I saw them do it on more than one occasion, wiped out my entire colony over a 6 month period.

 

Could it be something like a lysaretid worm or Eunicid worm. I've caught worms like these nibbling on Zoa's at night.

 

alright so if i see them again tonight ill pull them, the snails i have are Collonista snail are those ok?? or should i start to pull those, i have a TON of them in there so it will take me awhile if i need 2

 

If that is a fancy name for bristle worms, i did have one in my GSP, but when i moved my tank around i did a coral dip and took that out, but there may be more but i havent seen any in a very long time,and if i did id have to go buy another 6-line, b/c the one in my tank just vanished, havent seen him in about 2 weeks, ive checked the overflow, sump everything i could think of, and i cant find him, floor behind my tank all sorts of places.
