Confirm ID - Common Bristle Worm

Massic · Jul 1, 2021

Positive ID as a benign bristle worm? It seems that the presence of blue, or at least the lack of consistent overall red coloration, is one of the distinguishing factors between aggro 'worms and "friendly" 'worms? I've also seen in a couple places that the larger specimens are best removed from the tank to prevent them from getting too aggressive/exploring other food sources apart from detritus? This one is about 2" when it "contracts", and has been expelling substrate since I caught it. I've read that some places list fireworms as being carnivorous, but this one seems to have ingested grains from the tank bottom. Feedback/positive ID would be appreciated.

Based on the legs, I'm thinking it's potentially a fireworm rather than just a bristle worm.

Confirm ID - Common Bristle Worm

Do you agree that based on your experience this appears to be a large common bristleworm?

Yes, 100% common/safe bristle worm, should have left it in the 'tank as free CUC

Yes, common/safe bristle worm, but it should have been taken out at that size

It's a bristle worm, but it's not the common or benign type (Explain below please)

Complete miss-ID (Explain below please)
