Zoanthid?? Coral ID help

[WetBehindTheEars]

Hi all,
Can anyone tell me whatthis coral is that has randomly popped up in my tank? Forgive the algae, I had been away. I feel like it might be a pest species seen as it has clearly hitch-hiked from somewhere...

Appreciate your help!

They are invasive and more of a pest but not dangerous. You can buy aiptasia X to remove them or get a syringe with hot water and lemon juice and squirt in them. Even Kalk paste will kill them.

Majano and get rid of it before it spreads. Using a syringe, squirt lemon juice or kalkwasser powder mixed into a runny paste and inject into core of majano and it will melt away slowly

Thank you everyone! I was a bit worried when they popped up so quickly. I will have to get onto it quickly. Thank you again.
