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.

All are harmless and good for the system. Just leave them as they are.

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?

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
