That looks like aptasia to me and yes, they are a nuisance. They multiply like rabbits.
You can try and get rid of them with "Joe's Juice" injecting the solution with a syringe into its center, or a couple of other alternatives many members in here have tried successfully. Do a search for aptasia on the forum. Whatever you do DO NOT try to pull them out with tweezers or the like.
Good luck. |
