Snail ID
 

I have noticed a lot of eggs all over the glass lately. Today I noticed two different kinds of very tiny snails.

This one almost looks like a sundail snail.... But i'm not sure how to clarify. He was found nowhere near any zoas.

Also found a few of these guys. They have what looks to be a tube in the front. I thought they may be baby nassarius, but after some research, they are extremely rare to breed in an artificial habitat.

Anything I need to worry about??

First one definitely looks like a sundial snail. Just to be safe, catch out all those ones and get rid of them IMO.

The first one is a Collonista Snail - harmless. The second with the tube as the front that you describe sounds like it may be a type of Whelk - which is usually not good.

Here is a Sundial snail:

+1 to Collonista snail. I've always had bunch in my tanks that come out at night. Sundial snails have a more textured shell.
