Possible Coral Problem culprits

[CatoeSc]

I have a GSP that isn't doing well at all. It's a young tank with a number of frags, all LPS. None are taking off yet, but all but the GSP are at least coming out every day. Everything I have in there (at least intentionally) is reef safe, but I've noticed that the very small blue-legged hermits tend to be all over the GSP. I've always assumed they are just foraging, but now I wonder.

The GSP hasn't come out in days. I moved it to a higher spot and have been monitoring all my levels closely using RedSea titrater test kits for Ca, Mg, Kh, and Iodine. Mg seems to be the only thing that I have to replenish regularly... Some kh.

I have seen a LOT if very tiny snails that I didn't add... At least not on purpose. They are tiny, smaller than a BB. The shells are grayish there's no identifiable markings. I've also seen 2 of the small starfish that I'm sure we all have in our tanks. I'm not sure what to do. I've got prolly $240 worth if frags in the tank and really don't want to lose these guys. Any thoughts?

Well what other corals do you have? Small snails don't sound like a pest of green star polyps that I know of. Oh also gsp isn't an lps coral. Lps stands for large polyp stony and gsp doesn't have a skeleton.

Still new at this. Unfortunately I can't remember all names, but one is a leather, 3 are zoas, 1 is a mushroom, 1 is a frogspawn. There are 2 others I don't remember the name of. One has a soft purple look when it's closed, and the polyps are green. The other is a purple polyp that I believe falls into a pipe organ family(?). The mushroom appears to be getting chewed on.

I have 2 ocelleris, 1 goby and a banghai cardinal Along with the crabs and 2 peppermint shrimp. At least I think there are 2. I only see 1 at a time.
