Hello,

Bought a coral from local store, removed the holder base, and got these hitchhikers.

Seems like pistol shrimp and some kind of reef scalops. Should i keep them?

Thx

Will need a better pic of the first one, but it looks almost like a mole crab. I doubt it's a scallop.
The second critters look like tiny pistol shrimp, yes. Unless you have itty-bitty shrimp in your display that you really want, the pistols should be fine, they're too small to hurt fish or reasonably sized inverts and they look like a species that'll stay tiny.

This is the best i could get with this camera.

On second thought, that definitely looks like a scallop, must've been upside down in the first photo. It's open awfully wide, though, might not be healthy. It's so small that it won't cause any problems if it dies and decays, so definitely put it back, preferably in a fairly high-flow area, and see if it lives.

IT appears to be a flame scallop to me as well. Personally I'd leave it exactly where it is. There is something about that spot that it likes, if it's unhappy it will move on it's own.
