Breeding / Snails
Assassin snail
Snails · Easy

Breeding the assassin snail

Separate sexes; females lay single eggs, each in its own small capsule on hard surfaces. Tiny young hatch fully formed, hide in the substrate and grow slowly.

Full species page

Step by step

Pairing

Buy 6-10 snails. They have separate sexes.

Breeding tank

A 40 L tank with sand, plants and small snails as food. Hard water.

What starts it

Stable warm water and plenty of prey.

Eggs and young

Eggs are laid one at a time, up to about four per clutch, each capsule holding a single egg; hatching takes from a few weeks to about two months.

Raising the fry

Young eat tiny snails. Growth is slow.

Common mistakes
  • Not feeding enough snails
  • Soft water
  • Keeping with large fish

Male or female

Separate sexes, but males and females look the same and can't be told apart by eye.

Can I breed it in my tank?

  • Good for a first breeding project.
