Weird hair-thin starfish

[KeepSwimming12]

Hi,
I bought a large goniopora the other day and now I’ve found this starfish on one of my soft corals so I can only assume it came from that. I just wanted to double check whether this hitchhiker was a good or bad addition. Thank you.

Hard to tell from this picture but normally there a great addition to your cleanup crew. Cool things to watch there are a couple predator versions but if my memory is correct those have colors.

if I am wrong I’ll get corrected here below

The ones that are bad are often greens and I think reds but I never can remember if the red brittle stars are actually bad…
