The snail has been in my 10-gallon tank for three months. It’s active and keeps the substrate clean without causing any disturbances. I appreciate its calm nature and how it doesn’t stress other fish.

I bought one for my planted tank. It’s not aggressive and spends most of its time grazing on algae. I did have to ensure no fish eat it, but overall it’s a good addition.

The snail arrived healthy and has been thriving. Its dark shell stands out nicely in the tank. I’ve noticed less algae buildup since introducing it.
