My apologies if the answer is obvious, but I’ve not seen these before. They don’t seem to fit what I’ve read about hydroids. They have doubled in number in my 10 gallon over the past month, popping up in different locations around the tank. They behave almost as some sort of tiny tube worm or duster, retracting back into the rock if touched or disturbed. Sometimes the clowns will pick at them. Fully extended, they’re about 3-4mm in diameter.

Further apologies for the low quality photos!

Are they clear-ish looking or do they look like a baby feather duster?
If their clear-ish = aiptasia

Don't think their baby Aiptasia or Majano but sure could be wrong.

I'm going to try and ask this with out sounding rude but I want to know because you have a LOT more experience than I do. Why would you think this is not Aiptasia?
(Is it because the centers are to big?)
 

Do you quarantine new coral before adding it to your reef tank?
