Need help identifying invasion


New Member
I bought a rock with some mature Christmas tree worms and there were also some of “these things” that have now spread everywhere and are taking over the tank. They seem to come in many different shapes and sizes and resemble a small nem and when bothered disappear into a tiny hard black dot. Any ideas on what they are and what to do?E492E8C1-2874-4712-9EE1-5502586E5D09.jpeg

I agree with PSU4ME. Mojano anemones. They are considered a pest in a reef system and need to be gotten rid of. Do this carefully since you don't want to hurt other livestock in the tank.
