what is this

[old salty]

I am going to try to describe this in case the picture doesn't post. It is about 7" to 8" long and reminds me of a centipede.

Most likely a type of bristleworm.

Opinions are divided among reefers. Half hate them, half love them. What is always true is that they're great scavengers.

I take them out. Just a personal preference. Here’s an article on them..

Bristle Worms [Good or Bad for Your Tank?] | Fishkeeping World

The bristle worm is a saltwater species of the Cirratulidae family. Bristle worms are easily recognizable due to their elongated, segmented bodies and characteristic protective hairs on each segment.

Saw one in my tank a month ago. Haven't seen it since.

Fireworms can be a problem. Did you use Live Rock?

 

[old salty]

Yes I do have live rock about 100lbs in 75 gallon. The only things added were a couple of snails 8 months ago and Shoal grass 2 months ago. If it will not harm things and stir the gravel it can stay. The article was very good thank you.

Bristleworm.

Good Clean Up Crew for the hard to reach areas hermits/snails can't get to. He hitchhiked in live rock and there are more than likely more. Personal preference on keeping them.
