Asterina starfish and a bristle worm.

I’ve had both, personally I’d chuck. Bristle worms are nice until there’s 5,000 per rock.

Asterina starfish can multiply like crazy in a tank. Some are known for eating corals and others don't

I had both, if you have life rock then bristle worms are probably already there. I never had problems with asterina, but many did. Either way both of those are much more benign than aiptasia or majano.

Bristleworms are an important cuc member. Asterina are a good grazer for film algae but they can also go after some corals. I currently have a ton of asterinas and no issues with them and my corals but in the past I did.
