Two critters I'm looking to ID

[TwiTch18]

Found these critters in my tank today and I'm looking to get some info on them!

The first is some sort of Starfish. I noticed it hanging around the other day and decided to leave it alone. Today I seen it on my new corals and decided to get it checked out. Hopefully it's nothing bad..

The second one I noticed when the lights went dim. Looks like some sort of shrimp.

Any help is appreciated! Thanks!

The last image doesn't enlarge, but asterina starfish and then amphipod, probably.

Second one is definitely and amphipod. First one is some species of starfish.

Do those starfish eat coral? I seen it hanging around on the base of some soft corals.

Asternia star - Some say they eat soft corals, I have never had an issue with them. As long as the coral in question isn't in decline, it's more then likely just cleaning detritus off it.

Stomatella snail - Looks like a snail with a thumbnail for a shell. Great member of your CUC.

Amphipod - Some are parasitic, most are just fish food.

None are really anything to worry about, and do not need to be removed.
