Remove the rock (or frag) and chisel off the part with the hydroids.

I took the goniapora out and scrubbed them with a soft bristle brush and placed them back in clean water. Then put them back. I don't see them anymore,,,,,, yet.... Watching closely.

These are hydroids. Snip off at base of each stem and net and discard

If they get out of hand, I have found certain hermits will munch on them, like electric blue's and halloween hermits.

Maybe but the best remedy is to completely remove them.

How long can they survive out of water

Quite a while unfortunately. I had some on a rock and had it out of water overnight (the nooks and crannies were still wet) after spraying the droids with H2O2, and they still came back.

*There are a lot of different kinds of hydroids and maybe yours aren't as tenacious as mine were, but my experience with them leads me to recommend total removal.

I literally had hundreds, maybe thousands. I cannot even find one anymore.

And hermits were your only intervention?

Snoopdog · Apr 19, 2023

Yep, but a ton of them. Tons of blues, aztecs and maybe 4-5 large electric blues and 3 halloween. Plus time, it was not overnight but just a slow dwindling.
