Help ID these tiny snails please

[sil40sx]

One of my zoanthids colony doesnt look good, some opens up all the way, most half way, and the rest never opened up for several weeks.

Iv'e been reading/searching for a week now, and I decided to go to peroxide dipping route,. So I dipped the colony tonight and didnt see unusual bugs other than few asterina starfish and bristle worms,. And a bunch of these little boogers...

I know for sure the asterina starfish bothering my zoas (I caught them red handed, already manually took out several dozens of them), but do these snails are one of the reason why my zoa doesnt open up?

Thanks

They're collonistas. They're fine.

They're collonistas. They're fine.

Thanks, I'm glad to hear. Otherwise I won't be satisfied until I dipped all my zoa's. LOL

I'm guessing it was just the artesina starfish then. I already took out a lot of them, hopefully I see some improvements in a couple days/week.

This particular species of collonista seems to be very "popular" right now, as they are showing up in a lot of threads.

Do they get big, or stay small?

PS: I'll check your Hitchhikers link and see if I can find info.

They stay small. The large ones of the bunch in your pic will be about as big as they get.

Look in the tank in the wee hours of the morning and you'll see plenty more.

Oh I see. At least they don't eat corals (herbivore?), they're just nuisance.

I'll check tomorrow before I go to work.

Lol I told a friend I would put together a reef-warming package for him....these are going in there

^^^ Hahaha

I don't think they are a nuisance at all.

I dont either-hes just starting out so Im giving him some of those, a few starter corals, etc.

I like that they only come out at night LOL

 

[Lionfish Lair]

The other night the lights didn't go on until a few hours after dark.... there were tonnes. Mine are too small to see, though. They're just white dots. Just be careful if you have an acrylic tank. Anything with a shell can scratch if you don't see it. I run my hand over my panel before scraping.

 

[ahiggins]

I don't use acrylic but that's a good note

Actually I have to agree,. I just realized I didnt even knew these existed in my tank until I did the dip. I just assumed they are (or were) bothering my zoa's.

Their numbers get so high, you'd think oh oh... but I think the fact they mostly come out at night, makes it a non-issue. I've never had any trouble with them overwhelming pumps and I purposefully grew them to plague numbers in one tank.
