Astrea snail baby?


Northern Reefer
I didn't think snails reproduced in tanks but I have a pea sized snail with a pointy shell on my glass

it has the snail tenticles seperate body and mouth, could it be?
Google collonista snail

Ive had astreas reproduce. Also ghost shrimp (which arent known to captive breed), bristlenose plecos (difficult) and various tetras/danios/labyrinths.
I have had a snail baby blowup a few weeks ago, I can see like 6 of them around the tank real tiny! I have read that it CAN become an issue but at this point I am not worried. Maybe you have baby snails as well and just have not found the others?
