Hydroid (Hydractinia sp)is a pest... Cheers..

Second this ID. They're hydroids and they can really spread! Pest or not, it depends as some do look nice with neon green colouring. I would consider them more a pest because they have very powerful stings and will sting any coral nearby to submission.

How do they multiply ? I do not have them in the past, where did they pop from ? The rocks on corals ? Or adding water when buying fish ?
