Xtra stingy, fireworm?

[Afkomjorgen]

These are all over the tank, pack a nastier punch than my average bristleworms. Fireworm?

Yes.
Did you happen to put any ocean live rock (from Florida or the Gulf of Mexico) in the tank?

Get an arrow crab, they eat these freaks up! Those are nasty looking and hurt like a SOB when you accidentally get stung working in the tank

This tank is at work (salt water store). We regularly get liverock from local reefers and regular shipments from Indo.

Thank you for the recommendation! They are super weird
It wasn’t even this one, I accidentally wrapped my entire hand under a leather and had two 4” ones sting me good.
Yeah dang I was really surprised. Super glue helped but my hand was covered in bristles.

Thanks for ID, I was sure I had been stung before and it had been less intense
