I’d please. ( I hope it’s not what I think it is )

Hello everyone. So I have found a couple aptasia over the last couple months but as soon as I see them i have removed the rock and just leave it to dry out.

Either way i saw this in the middle of my zoa rock and was wondering if someone could tell me what it is please. I’m hoping its not aptasia as i though i had it out as I haven’t seen any in a few weeks plus.

Thank you everyone.

Hydroids - not generally a good thing, but these don't seem to be bothering your zoas, so they might not be too harmful.

Thank you appreciate it. Do these spread or cause damage to other corals if you don’t mind me asking?

Some species do some don't - we're not sure what species are harmful/invasive at this point and which aren't, though, and the invasiveness can vary depending on individual tank circumstances.

Thank you for the info. I will start my Google searching and learning now about this pest. Hopefully it doesn’t get worse. Appreciate the help.
