Hard to tell, some kind of a nudibrach

probably a stomatella snail. google that and see if it matches. good to have if that it what it is

If they move, I'm not sure. If they don't move then it looks like a sponge of some sorts.

I think knowing if they move or not is the key to an ID.

it doesn't look like they move, the sump is dark 24/7, and that's where they are growing if that helps anyone

No movement usually tells me its a sponge or other filter feeding animal. Good for the sump/refuge.

I have had them in my overflows and sump before. I believe they were called pineapple sponges. They are a good sign that your tank is mature and healthy. Nothinh to worry about there.
