Snails and Bristle Worms?

[Nathaniellund17]

Hello All,
I'm dealing with a pretty bad aiptasia infestation, and have decided to go the route of adding Berghia Nudibranchs to my display. With that, I've been monitoring the tank a lot more at night. I'm seeing a lot of little critters attached to the glass which I think are snails - but not sure. Any thoughts?

Also, I'm not worried about having bristle worms, and appears I definitely have them. But I just want to ensure these are not the bad kind and that they won't wreak havoc on the tank. My understanding is that common bristle worms are really thin - which I believe these ones are thin whereas fire worms are fat. Thoughts?

I have bristle worms in my tank, I haven’t noticed them do anything harmful. Sometimes if I see a large one I will remove it. I consider them as part of a clean up crew. As for the aptasia I have had luck with it pepermint shrimp, but it seems like people have different experiences with them.

Could you get a picture of the shells of the snails?

And those bristle worms are nothing to worry about.

The snails are most likely collonista snails. If the id is correct, they feed on algae and are harmless

Not sure if these pics will work, really hard to get the camera to focus on the snails. If this doesn't work, maybe I can try to pull some out.

If you have trochus snais, those could be their babies, or they're collonista snails.

Yes, I certainly have trochus snails, so that very well could be the id. I was just surprised to see how many there are. With that though, regardless of if they are trochus or collonista - they're harmless to the tank, and are good for a cleanup crew, correct?

Correct.
