Breeding the bladder snail
Hermaphrodite; mostly cross-fertilises but 10-30% of eggs can come from self-fertilisation. Populations can double in as little as 4 weeks.
Step by step
Buy 3-5. They are hermaphrodites.
A 10-20 L tank with plants.
They breed in any warm tank.
Lays about 50-100 eggs a week in gelatinous egg sacs; eggs hatch after 15-20 days.
Young eat algae and food.
- Overfeeding
- Using as pet snails only
- Keeping with loaches
Male or female
Simultaneous hermaphrodite: every snail is both male and female and can lay eggs.
Can I breed it in my tank?
- Good for a first breeding project.
Day-by-day plan
Typical for snails
- Day 0Egg clutch
Clutches appear on glass, plants or above the waterline.
- Day 14Hatching
Baby snails hatch in about 2–4 weeks. Too many? Feed less.
A general guide for this breeding type. Days change with temperature and species.

Simulator: try it yourself
Set up a virtual breeding tank and see what would likely happen.
- They spawned.
- Fry had nowhere to hide.
