Can anyone help me with this, I intended to take a picture but by the time I had got my camera the darn thing was hiding.
I have found a small snail in my reef tank. It's about 1cm shell length, very vivid black and white spots on the shell and also the snail itself is the same mottled colour when it appeared from the shell.
yes, its likely a Cerith, you can get some good info on the Project DIBS website. they are a species that is good to have and known to breed in captivity.. feel free to contact BrianPlankis (founder of Project DIBS) im sure he would welcome another breeder if you are interested..

I think the description so far is too vague to guess at the type of snail it might be, although odds are good it could be a small cerith as they are common hitchhikers.
But a picture, or a least a comparison to a picture is needed. You mention it looking like Cerith #2, so that is good, but there are MANY other genus of snails that have that same general shape of shell. Most of them good, but some bad.
A couple of questions that might help:
1. Can you see any visible eyes when the snail is cruising around the tank (with tiny snails like this you need to find them when they are on the glass).
2. Do you see the snail grazing on the rocks? Do they appear to be attempting to eat algae or something on the surface of the rocks?
3. Do you see a mouth actively trying to feed on the glass/rock?
To Id a snail take a pic of the front... like ya would if it were crawlign along... and then flip it over, make it retract and take a pic of it's "doorway".
Well now... look at that. There's only one? Grab him out while you see him. He's looking like some sort of whelk. Whelks are typically not a great snail. Like the bumblebee snail.
How could is that old camera of yours :-) If you could take him out, tickle him so he goes all the way in and then snap a pic it would be great. And then flip him over and get one of the shell.
