Breeding the surinam toad

Pairs spawn in repeated upside-down turnovers in amplexus; the eggs sink into the female's back skin and develop directly, emerging as about 2 cm froglets after 12-20 weeks (3-4 months), with no free tadpole stage.

Step by step

Pairing

A group of adults of both sexes in a large tank.

Breeding tank

150 L+ tank with deep soft water, no strong flow, dark leaf litter.

What starts it

Raised water level and temperature with abundant food.

Eggs and young

About 60-100 eggs, embedded in the female's back; young emerge after 12-20 weeks.

Raising the fry

Froglets emerge fully formed; feed small worms and daphnia.

Common mistakes
  • Strong flow stresses them
  • Bright light
  • Mixing with fish

Male or female

Adults of both sexes are a similar size; a female ready to breed shows a ring-shaped swelling around the cloaca, and only females carry eggs in the back skin.

Can I breed it in my tank?

  • Takes some experience.
