What size aquarium is suitable for Stomatella Snails?

[myrcies]

Hello everyone!
I know I asked earlier for some advice/ethics on my 2.5 gallon [1].
However, I forgot to mention I was gifted three Stomatella Snails from a local fish shop and have been keeping them in a single gallon.

Recently, I was that they'll grow quite a bit. Should I be worried about these snails? Should I move them elsewhere?

Thank you so much for all of your help. I get worried my tank sizes are too small and want to make sure everybody is happy.

You can keep them in the single gallon indefinitely but you’re probably going to have to feed feed them.

As long as they have food, they will be fine in just about any tank.

I have probably 20 in 3.2 gallon. I started with a couple and they multiplied. They reproduce pretty quickly for me.

They are my favorite snails. I love the way they look especially the black ones that have the pink/purple shell.
