Fire-bellied toads breed like most other amphibians. They lay eggs after mating. These eggs then turn into tadpoles that eventually grow into little Fire-bellied toads. Be careful with these eggs as most animals will thing they are a tasty treat. The best way to insure the eggs are safe is to provide lots of hiding places.
They lay there eggs in ponds, or other fresh water. When they hatch they start off as tadpoles. Eventualy they grow limbs, and slowing develop into frogs. They then move out of the water, on to land.
The fire bellied toads prefer to have an underwater cove in which to lay their eggs. The male develops pads on their fingers to hold onto the females more easily during mating. Keep them moist at all times.
The female will lay eggs in a nest that looks like a glob of foam and then they will hatch into tadpoles, which will appear as tiny swimming fish-like creatures, as they grow they will look more and more like frogs.
These toads spawn like other toads. It takes about a week for their eggs to hatch. If you try to mate these frogs, after eggs are laid remove the parents.
