The mystery snail is a freshwater snail of the Ampullariidae family. These snails' colour variations, ease of care, healthy algae-eating behaviour, and peaceful temperament make them popular with aquarists everywhere. 

As far as snails go, the mystery snail is one of the more exciting species to keep in the home aquarium. If you have a male and female, they should breed without your intervention. All you need to do is make sure you have a male and female, which is not as tricky as you think. 

The easiest way to confirm the sex of the mystery snail is to look inside its shell. There is a really straightforward way to visually tell the difference between males and females that anybody can do.

Yes, that is correct. 

Grab your mystery snail. Then gently hold it on its back until the snail begins to open out. Patiently wait for your snail to come out and say hello. Wait until its body is out of the shell as far as possible.

You will eventually see one or two small holes on the underside of the shell behind their body. Male mystery snails have a single hole in their shell while females have two.

It is that simple!
