Breeding the northern map turtle
Egg layer: females nest on land from late May to mid-July (peak June), digging flask-shaped nests in sand or soft soil; usually two clutches (1-3) a season. Courtship and mating happen in spring and autumn.
Step by step
Pair.
Large aquarium with a basking spot.
Winter cooling.
6-17 eggs per clutch (about 12 typical), 1-3 clutches a year; incubation about 75 days.
Hatchlings are fully independent: house them in shallow warm water with a basking spot and feed small pellets, worms and daphnia daily.
- Undersized tank and weak filtration
- No UV or basking heat (soft shells, poor growth)
- Releasing unwanted turtles into the wild
Male or female
Females are much larger (17.5-27 cm vs 10-16 cm) with broad heads; males have long thick tails with the vent behind the shell rim and long front claws.
Can I breed it in my tank?

Set up a virtual breeding tank and see what would likely happen.
- Without live or frozen food the parents aren't in breeding condition.
