Need HELP to ID!!

[preston469]

I have googled everything possible and have looked at hundreds of pictures of the good or bad and can't find anything that looks like this. It is very slow moving and won't budge off the rock trying to ply it off with my finger nail. I just need to know if its good or bad. Thanks for looking :xd:

I believe in this next photo is a group of feather dusters, can this type be an issue?

What could that be?

The dude with a shell is a limpet. They are good for the tank. They eat algae.

I dont know the other one =/

+1 limpet.
I'm looking at this on my phone, so I can't see it really well, but the second looks like a bristle worm or maybe a leg of a brittle star. Does it move around a lot?

I know I have two little brittle stars a little bigger than a quarter then that's the first time I've seen that in these pictures lol,

It may be a keyhole limpet. I would go ahead and remove it. They aren't bad per se, more along the lines of "Reef Safe with Caution." They can eat the soft tissue of SPS if there isn't much algae left for them to eat. Provided you have an SPS system. If not, I'd leave it be.
