Worm ID

[SandJ]

I finally got some good pictures and videos of this worm. Would love to get an Id on it.

• It lives in the sand.
• Has always been in the same place
• Stretches out of the sand onto nearby rocks and corals
• It is at least 6" long
• The end that comes out of the sand is forked (hard to describe, kinda looks like a dolphin's tail)

Look up Bonellia viridis and see if it matches.

Ack! That is it! Most things do not bother me, but this has me slightly creeped out. Going to have to research this a little more

And thank you @Lionfish Lair. Did not exactly know what to Google on this one lol

Is this of any concern to my fish? Could it be responsible for my firefish's disappearance?

He's just licking around on the rock. Think of him as a divided peanut worm. They do have a toxic defence mechanism, to avoid being eaten. That's more of a deterrent, however, not something that would kill a fish.
