Identifying a few critters - can you help?

Attached photos are not great, but hopefully good enough.

The first is of a small (1/2 inch) snail like animal in my tank and there seem to be a few of them. Are they harmless?

The second are small worm like critters in my sump. Are they ok just left there and is it a good idea to remove them and/or place some old coral within my sump?

Many thanks.

First is a stomatella snail, and the second is a kind of fanworm. Both beneficial.

The second photo is Spirorbid worms. They are beneficial filter feeders. I also think the first one is a Stomatella. Does it look like the photo with a small semi-flat shell on it's back?

i have 5 of those suddenly showed up 4 months after my tank had been set up all different color.

Stomatellas will breed in the reef too. Their population will flourish and fade according to how much food is in the tank. Nice to have a self-adjusting clean up crew. :D
