Some kind of snail or worm?

[Danjoc92]

Hello all. I am hoping someone can ID these creatures ( white snail/slug/worm creatures between the glass and weir ) and hopefully give me some good news about them. I’ve not noticed them until last night and there seems to be a lot!

Clean up crew, usually a sign of a well established tank, you bought rock or sand or something that had them and they are happily reproducing.
They will parade up the glass when the lights go off in my tank. Biggest on in my tank is about half a dime and when they get that big they don't seem to hide during the day so you can kill them with magnet glass cleaners, though they usually just let go, I try not to bother them.
I forget the name, I am bad at remembering that kind of stuff now that I am not a kid.

Yeah, look likes limpets - so like Stealthreefer said, they should be good CUC.

Oh perfect. I was worried they could have been a pest. Thanks for the info!

Mini limpets.

I just started seeing these too. Good sign and they are great algae eaters.
