Those look like little Nassarius snails. Either that or some variety of Whelk.

The whelks that are carnivores don’t go under the sand, I think you are good.

Whelks do bury themselves sometimes, but safe nassarius don't climb on the rocks...

The safe nassarius (technically also whelks) that we usually want in our tanks don't generally breed in the tank - at least not very quickly. If you're seeing a lot of these then you *might* have an undesirable species ...

Did you buy any macro for a refugium?

Like up high on the rocks?

Like up high on the rocks?

No. They'll go up about 6" or so and then back down. But that's usually after I just fed the tank.
