Breeding the japanese fire-bellied newt

Breeds in spring to early summer (April-June in the wild) after a tail-fanning courtship; the female lays eggs one at a time, folding each into the leaves of water plants. A winter cool-down of 5-8 °C helps but is not essential.

Step by step

Pairing

Keep groups with equal sexes.

Breeding tank

Aquarium with plants and a land area.

What starts it

Cool winter followed by spring warming.

Eggs and young

About 100-400 eggs per season laid singly (AmphibiaWeb: about 200); they hatch in about 20 days and larvae metamorphose after about 3-6 months.

Raising the fry

Larvae eat daphnia and brine shrimp; metamorphose in months.

Common mistakes
  • Warm water
  • Dirty tank
  • Fish tankmates

Male or female

Males are smaller, with a swollen cloaca and a flatter, wider tail; in the breeding season they develop smoother skin, a bluish-purple tail sheen and a thin filament at the tail tip (absent in some populations). Females are larger.

Can I breed it in my tank?

  • Good for a first breeding project.
