Slug???

[singold]

Small slug looking things hanging out on Metallic Green polyp rock. Also, they crawl on glass occasionally. They have a white underbelly and charcoal top of body and attenae. They do not appear to have a mouth like snail when watching them crawl up glass. They are not a Stomaella Snail either. They are more elongated when crawling up glass. Sorry too small to take pic, maybe a centimeter long. Anybody know what these might be. Don't appear to be bristleworm or Flatworm, either. Any ideas???

Sounds like a slug to me.

Should I remove them or are they beneficial if sea slug?

I would guess you would need to identify it first and make sure it not going to be a problem for you. I have a little black one in my tank and discovered it was reef safe and a beneficial cuc crew member. It came in as a hitchhiker so i'm pleased with it. I see it every evening just after lights are out on it's way to work.
It's part of the dream team.

:lol:

Thanks Playa, dream team, funny. I have my Lawnmower Blenny playing center.

Singold, chances are pretty good that yours aren't beneficial. Search for "arminid" or "arminid nudibranch" and see if that looks like your animal.

Cheers,

Pagojoe, you're exactly right! This is the creature, I will remove it ASAP, I see it crawling on glass occasionally, also. -Thanks
