Transparent tube like thing?

[PotatoPig]

I noticed what appears to be a semi-transparent tube like thing next to one of my acans. It also has some scattered luminescence under the blue end of the lights, and doesn’t appear to have any tentacles.

Apologies for the not great photos, getting a good angle is difficult due to location, and the phone camera seems to have a very hard time focusing when not viewing straight-on.

Are you talking about this?

If you are, this is a bristle worm. A usual harmless detritivore.

No, I meant the purplish thing the top-right of the circles area you drew points to.

Okay. The pictures are very fuzzy so it's very hard to see. Possibly a type of sponge? I could be completely wrong though.
