Hidden coral stinger? Or random worm?

[lci3447]

I'm seeing a sweeper (or worm) from the rocks in the DT. I'm at a loss, is this a hidden coral or something bad. (Was watching the boy's/ playing sea of thieves so the audio). I can't work out what it is. Two separate times this 'sweeper' came out

there is no picture attached, but there are a lot of worms in our tanks.

Looks like maybe the end of a bristle worm based on shape and how it moves but hard to tell from the vids.

Video is a little blurry. String with little puff branches? Look up Digitate hydroids to see if it looks like a match.

So, do I need a better video . I've just seen something come out of the rocks that I can't explain...

Dino's it's not, just a good tank and a worm making his mark, just want to make sure he's not trying to take over tank

Not dino, digitate hydroid.

Does it look like this?

Yes actually it kind of does. Thanks, I hadn't come across those before but dang, they don't sound like fun.
