Have these little round things in a few places in my tank, not sure what they are, they are flat and colorful.

Also this slug thing, only see it at night, but has gotten big.

Thanks

Looks like a sundial snail. Remove all you can find. Eat zoas.

I googled the sundial snails and it does not look the same. Although it looks flat in the pic, the shell is not flat on one side, its like one side of a peanut shell with the snail coming out of the end. The few times I've seen it, its been no where close to my zoas.

Any other ideas? Also, any ideas on the second pic - not a great photo but its close to the back of the tank. I have quite a few of these round things.

Snail dosent look like a stomella , but i could be wrong . The description you gave fits stomella snail . The second pic is of some sort of nocturnal nem i have some too they seem to be fine.

definitely not stomatellas, I have a few. Although I'm not quite sure I agree 100% with Paddyob on sundial, after looking at some my self yours dont seem to have the flat shell on one side, but I dont know if all sundial share that characteristic. google Live rock hitch hikers theres a few websites, I cant remember off the top of my head, but the may be of more help

google Heliacus snail, I dont know if thats the same as a sundial. similar but different lol. and I agree with the nocturnal nem. check out http://www.chucksaddiction.com/hitchhikers.html for more on hitchhikers

I think it could be the stomella snail. Each time vie seen it it's been grazing on the rocks.

Will look up the nocturnal nems. Thanks!
