Anyone know what this is? it came in on my frag of zoas.

it wasn’t this big when i got it. it just kept growing more and more till it got to this size. and to be completely honest, i kind of like it and would probs prefer it to be on its own with no zoas.

If I had to guess I would say mushroom polyps, but I will let someone who recognizes them reply!
