Also on a side note I’m pretty sure that little snail next to it is a baby astrea if not please educate me as they all mated in my reef tank and I now have around 200-300 in my 100.3 reef tank.....LOL I love them tho picture of large group of them below

Idk if it’s bad having that many but I’d say there’s at least 2 snails for every cubic inch

Looks like a Stomatella to me. Completely harmless and as I understand, quite rare.
I have millions of teeny tiny snails covering my rock at night. They're not bothering anyone and are great cleaners.
