some sort of paly

Is that a bad thing? Sorry, im oretty new to this.

its a coral.

Paly or Zoa.

It's good.

Might even get more colourful if you give it enough light.

Thank u!!! Much appreciated!❤️

it will look green under blue light. It will grow like weed unlike other kind of zoa :).

Look like palys to me too. If they stay brown get rid of them - unless you like brown :wink:. They'll overgrow your rock. I had similar ones and they're a pest.
Above your featherduster I see a vermetid snail - it'll have a hard tube. Mash the crap out of it before it spreads. You've gotta dig into the rock a bit to kill it.

Never had a problem with vermited snails...

Why kill them?

You don't like the web?

Also, thats probably a Hydrozoan...maybe not a vermited.

Agreed. I find them interesting. I guess I've never had a huge amount, but the ones I had were fine for years.

If their web gets on corals it can irritate them if it stays there for extended periods of time.
