That is what I’m worried about. I have not added anything recently to the two tanks I’ve seen them in. These have been in one of my tanks for at least a year & I really haven’t seen them grow ever. Thankfully, that system is just softies - leathers and Xenia. I just want to be extra sure of what they are because I do have a clam in one of my tanks. I don’t see them in that tank ever.Those don't look like ceriths to me. The shell seems different.
Have you added any rock, frags, or macroalgae recently?
They don't look like my dove snails babies that roam around my tank. Dove snail's foot extends the length of the shell, not just the top light these photos.
I suppose you could try an experiment and put the clam and a handful of the snails in a small tank/container and see how the snails behave...That is what I’m worried about.

yep- cerithI feel fairly certain that these are baby Ceriths but I wanted to get another opinion. I have both dwarf Ceriths and larger ones in several of my systems, maybe all of them? But I’ve been seeing these guys pop up and they really come out at night for the most part. Let me know what you think!

They seem to stay in the rocks and glass, so I would say that they’re eating algae. I’d be afraid to stress my clam out too much by transferring it.I suppose you could try an experiment and put the clam and a handful of the snails in a small tank/container and see how the snails behave...
Right now, do they seem to be algaevores?
Unfortunately, I'm not as good with snails like these (I tend to struggle with snails that don't have obvious differentiating features) - so I'm not sure on the ID, but the texture of the shell leads me to believe it may be a Cerith.
It is unlikely, but I've seen other threads (see below) of dwarf ceriths reproducing quickly in our tanks, and some snails produce benthic larvae (i.e. some snails hatch as fully-formed, crawling subadults rather than planktonic larvae), and some (including some Cerithium spp.) are thought (unconfirmedly at this point) to exhibit poecilogony with some eggs hatching into planktonic larvae and others into benthic subadults.They don't look like my dove snails babies that roam around my tank.

I don't know anything about the dwarf cerith snails life cycle, but it is unlikely to be the normal cerith babies because their eggs hatch into a planktonic stage, which barely survive mechanical filtration. My ceriths lay eggs all of the time, but I don't think they will make it to the stage where you can see them roaming around.
Learn something new every day. I didn't know anything about the lifecycle of dwarf cerith, but they are on the list of clean up crew members I want to add to my tank for diversity.Unfortunately, I'm not as good with snails like these (I tend to struggle with snails that don't have obvious differentiating features) - so I'm not sure on the ID, but the texture of the shell leads me to believe it may be a Cerith.

cerith snails
Is it common for dwarf ceriths to reproduce like mad? I started out with 25, now have hundredswww.reef2reef.com

What are these snails breeding in my tank?
So whe lights go out atleast a hundred of these tiny little snails seen high up on the glass in this picture come out. They seem to eat algae. Smaller than a bb. What are they?www.reef2reef.com

Dwarf Cerith Reproduction
How quickly do dwarf ceriths reproduce and how? I have added about 20 to my tank from reefcleaners about 3-4 months ago. Last night I was looking at my...www.3reef.com
Interesting that one of the threads you linked mentioned that they came from reef cleaners as that’s where mine came from too! I suppose I will continue to assume they’re Ceriths unless someone IDs them otherwise. I will be keeping an eye on the tank with the clam though to be sure they’re not on him.Unfortunately, I'm not as good with snails like these (I tend to struggle with snails that don't have obvious differentiating features) - so I'm not sure on the ID, but the texture of the shell leads me to believe it may be a Cerith.

RC has sent my the wrong thing before .. not saying this is what happened but their collection team does not always bring in the actual species RC advertises and sells. Buyer beware for sure.Interesting that one of the threads you linked mentioned that they came from reef cleaners as that’s where mine came from too!
