Had this colony for many months. Noticed this guy got just big enough to see. Verify what it is please.

grabbed a few. thin flexible shaft, reminds me of a keratin or collagen. looks like heads are glowing green maybe.

I have had a few just like yours but it has been a long time ago, try cut back on the feeding and it should go away.

 

[jason_mazzy]

so everyone agrees to pull these guys with tweezers?

 

[miyags]

Get'em while you can. It's too late for me, after 20 years they are everywhere.

With tweezers siphon at the same time if not it can land on another rock and grow.. also put some epoxy putty where it was after you pull it out so it doesn't grow back

Or a lil blob of putty w glue.
Mine are now gone.

Hydroids can be worse than aiptasia and spread like crazy, especially the brown ones (water nutrients and photosynthetic). If u tweeze them do it outside the tank and rinse the rock well so the spores dont spread. Had them on my 1st reef tank and i was gluing and putting putty everywhere. Finally got so fed up and i broke the tank down, boiled the rocks. I saved a couple small pieces of rocks w hyroids, placed in small bucket w old tank water w a lid. That bucket has been sitting for about a year, rocks lightish green-white and the hydroids are still there! My second run, i qt everything and if i suspect hydroids no way the new frag goes in the dt.
