Thingies in macroalgae

[maxberter]

I ordered some carpeting halimeda to add to my tank and see a few critters in the bag.
At least 2 brown worms and 1 starfish thing.
Can anyone identify and do I want them in my tank?

probably bristle worm, I don't like them and would remove, some people think they are good CUC members. Micro brittle star, I like these and have/had a few in my tank (I never see them but they are pretty good at hiding).

I see bristleworm and brittle star. Brittle good and bristleworm while not welcomed in my tanks are desired by many for clean up crew as they eat uneaten food and detritus.

Agree^^^

Worms give people the creeps but they are useful critters.
