Breeding the red-tailed knobby newt

Breeds in the rainy season (about May-July in the wild; March-June in one keeper's tanks). After face-to-face circling courtship, the female lays one batch of eggs over 1-3 days, mostly at the land-water edge, often on plants just above the water line; move them fully into water or they dry out.

Male or female

Males are slimmer and smaller; females are larger and heavier. The surest sign is the cloaca: slit-shaped in males, round and cone-shaped in females (sexable from about 1 year old).

Can I breed it in my tank?
