Clear flatworm creature Gulf hitchhiker

[diverjm]

Hey guys, hoping someone can identify this clear flat worm like creature I found in the back chamber of my Biocube. It hitchhiked from Tampa Bay Saltwater Live rock/sand. It looks like it has a skeleton structure, is extremely sensitive to light, as is super fast moving.

Bump. Any ideas??

Maybe a lancelet?

clear flat worm like creature

could it be a flatworm? jk

its nearly impossible to see in the pic but IME anything flat like that has got to go.

It is a lancelet which is a segmented worm that prefers substrate with shells and is a hitchhiker that scavenges. If they are thriving, you may be overfeeding or lacking in siphoning and maintenance.

I agree. My best guess is lancelet

Thanks guys and sorry for the crappy picture. I agree, it’s a Lancelet.
