Worm identification

[Ariel.Negron]

Hey there,

I’d love some assistance ID’ing what the heck this worm may be that I found in my quarantine tank. I recently put macro algae (Chaeto) that I ordered online and out of pure curiosity of never having looked from beneath the tank, found this cool looking worm (which I hope is not bad aka reef safe). I don’t see any bristles in the sides, seems to really stay under the gravel consuming detritus, doesn’t look much like a predator, but who knows

Could be a bobbit worm...

Can you see it's head?

A true bobbit has 5 anttenae in a star shape, located on it's head.

They eat detritus, fish, and a lot of other things, so they are not reef safe.

In the video it seems quite large, is it actually a few inches as it seems?

Possibly a peanut worm?

Yeah, it easily has about 4-6 inches. I don’t see any antenna or spikes on the front or end. When it goes to (what I assume is) consume detritus, it simply flattens out and somehow absorbs the material, but I don’t see any barbs

And if you notice the body, it’s translucent, with what looks like a coil internally. Every photo of Bobbits or other marine worms have not appeared like this

It still looks like a peanut to me...

Possibly a peanut worm?

Yeah, a deposit-feeding peanut worm (Sipunculan) would be my guess too.

Understood. Thank you guys. I’m thinking of keeping it and placing in display. Based on google, peanut worms are harmless and are actually extremely beneficial. Unless you guys think otherwise

Peanut worms are good, so I'd keep it.
