Direct developer: eggs are carried under the female's tail for a long time (Garnelio: 7-9 weeks in text, 4-6 weeks in profile); 40-80 young hatch and grow slowly. Use plenty of oak or beech leaf litter as cover and food.
One male and 2 females in a large tank with hides.
Large tank with caves and sand; separate female when berried.
Seasonal temperature changes and good feeding.
40-80 young hatch after roughly 4-9 weeks.
Juveniles are tiny crayfish; feed meaty foods and keep separate to prevent cannibalism.
One breeding tank for the blue moon crayfish, drawn to scale from the breeding guide.
Water: 20–25 °C · pH 6.5–7.5 · sand bottom
A plan from the breeding guide and an adult size of 12 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 blue moon crayfish in numbers.
In total: 3 tanks, about 490 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.
Adult males have a soft, white or cream patch (decalcified swelling) on the lower edge of each claw; females lack it. Genital openings: males at the base of the 5th walking legs, females at the 3rd.
Typical for shrimp
Eggs are carried under the tail. Keep the water stable and don't move her.
After about 2–4 weeks tiny shrimp hatch. They graze on biofilm and moss.
Keep a sponge on the filter intake. Feed powdered shrimp food a little at a time.
They can breed themselves at about 3 months.
