Need help Identifying

[jacob_visou]

There seems to be something growing. Idk what it is. Is it bad or good? I’ve noticed it a few days ago it was small and I thought it was leftover shrimp I used to cycle but when I had the lights on it grew bigger. This is live rock.

A pic in white light would be great, just looking at it it’s probably a invasive sponge coral.
