Snail harmful to sps?

[MichaelW]

Not sure if this would be the right forum for this, but this is where I hang out most the time with all the people I usually interact so thought I would ask here.
At night I have hundreds and hundreds of these tiny tiny white snails everywhere all over the place. I wondered if anyone could id them. I have looked for similar pics online but couldn't find any I was sure were the same. In the picture They are near zoanthids, but They are all over the whole tank. I don't think They are sundial snails but I may be wrong.
They are very small

Do you have trochus snails in your tank? If so, most likely babies. I have quite a few in my nano.

Upon further looking my guess is either baby trochus or I think more likely collonista snails. Either way I believe harmless, so I think all is good.

Yeah man those are collinista snails. I have them in my tank too.
