Noticed on zoas tonight?

[ralquist]

Noticed this patch of zoas tonight after a herm ran them over. Seems to be quite a few only on this portion of the rock growing all around the base and stem of the zoas. Any ID help would be much appreciated! Thanks in advance!!

Looks like hydroids to me. They can be a bother but if they’re not bothering your zoas, I’d leave them. Some can sting you as well as your corals. They can also spread and become a pest over time. There are some threads on here regarding removal if it gets to that point.

Thanks so much for this, I will take a deep dive into hydroids!
