Snail identification

[ragnarokas]

Hello,

A lot of small snails appeared in my 100 liter nano reef. At first I thought about colonista , but then some of that small snails began to grow and looks like a small turbo, some of them are already ~ 1 cm . Could anyone advise ?

Looks like a tropical species of periwinkle IMO theres so many species I'm not going to try guessing the latin name id likely get it wrong lol.
