Anyone know what these things are? At first I thought they were aiptasia, so I got nudribrachs but they didn't even touch them. When I took out the rock, they are in small hard tubes. They started out in one rock, but I'm starting to see them propogate into other unconnected rocks. What are these and how do I get rid of them? I feel like they're going to be taking over soon.

Thanks for the responses. How do I get rid of them, hydroids or yellow polyp. They're getting into my other rockscape.

Take out rock and bleach it m, rinse it well dry in sun and put back in. Otherwise you will never be rid of them.

Thanks! You mean dip them in bleach (sorry newbie). How much bleach to water? When I put back in, does it spike up any water chemistry as its curing? TIA.

colonial hydroid... these things are a pain in the butt.
i fought them for many months, with putty, tweezers, and a blowtorch.

they have a free swimming jellyfish-like stage, that's how they spread.

good luck!

gloves are always a good move, any specific reason tho?
They are related to the jellyfish so I’m guessing they could sting you. Just saw this online for possible natural predators that would eat them.

-The lynx nudibranch (Phidiana lynceus) - Only eats hydroids, especially fond of Myrionema amboinense.
-Pterolidia Ianthina - sea slug that feeds soley on hydroids
-Sea Urchin Salmacis bicolor- Good eater of Myrionema. but very slow & can not get into the pores of the rocks where roots are.
-Diadema setosum (Sea Urchin) - Good eater of Myrionema. but very slow & can not get into the pores of the rocks where roots are. Will also eat sps corals
-Flameback Angelfish (Centropyge acanthops and Centropyge loriculus) - Hit & Miss and will occasionally nip at your corals especially your sps and some polyp corals.
-Dolabella auricolaria - sea hare

They can sting, but if you have any cuts on your hands. It makes it a lot easier for them.
As with all venom. You never know how your body will react. May not have any issues. Or, mild discomfort and swelling. Up to you though.

Live Rock
Ah, like I said I'm a newbie. I actually got it from a fellow reefer here. Coral I purchased was attached to a small rock. I dipped it in CoralRx, thought nothing of it since it was only a few polyps then. Now they've grown into a colony and spreading to my other rocks.

Always fun to see a hitchhiker deep down you always want to keep it. That’s why I have a 10 gallon I call my “Observing Tank”..It’s not really a QT because I know somethings I put in there I don’t plan on ever taking out.
