Buy 5-8 snails. Females are larger.
A 40-80 L tank, cool water of 15-25 C and plants.
A cool season followed by warm water.
A female can carry up to 120 young.
Young eat algae and fine food. Slow growth.
One breeding tank for the japanese trapdoor snail, drawn to scale from the breeding guide.
Water: 15–25 °C
A plan from the breeding guide and an adult size of 5 cm. Tank shape is a standard 2 : 1 : 1.2 box, at least 6 adult lengths long. Check each step in the guide above.
A 120 cm rack for breeding the japanese trapdoor snail in numbers.
In total: 4 tanks, about 240 L of water. A litre of water weighs about 1 kg, so check that the floor and rack can take the weight.
Sizes are worked out from the breeding tank in the guide. Tanks fit a standard 120 cm rack when they can; bigger tanks go on their own stands.
Separate sexes; females are slightly larger than males.
