As long as both your male and female Siamese fighting fish are healthy, learning how to breed Bettas is not all that challenging. The mating, spawning and hatching process of the Betta species is simple and quite predictable. However, making sure they are healthy enough to breed can be a bit more challenging.
The entire reproductive process of the Siamese fighting fish requires three tanks. The first one houses the male, the second the female and the third is a spawning tank specifically dedicated to hatch new Bettas from their eggs. Every tank should be close to the ideal temperature of 78 degrees Fahrenheit.
Any temperature less than that can have varying results during the mating and spawning sessions.
Part of learning how to breed Bettas includes preparing the spawning tank. It is important that the surface water of the tank be calm as any type of current might disrupt or destroy the nest that will be built by the male.
As soon as the spawning tank is ready, the male needs to be placed inside, and the female placed inside a clean jar with a lid, filled with water from her tank. Securing with a string or rope, suspend the jar in the spawning tank, so she can be viewed by the male.
The male will display himself to the female and the reproduction ritual will begin. During the first 24 hours, the male will expel mucus from his mouth and make a bubbling nest that floats on the surface of the water. He generally works continuously building the nest, taking numerous short breaks to appear in front of the jar and display himself to the female. During the same time, the female begins to darken in color, as vertical striping appears on her scales.
The next process involves emptying the jar with the female into the spawning tank. Once the female has expelled her eggs, she should be removed from the tank. After 48 hours, the male needs to be removed, once the eggs have begun to hatch.
The process of how to breed Bettas is simple as long as these guidelines are followed. A single reproductive event can spawn hundreds of hatchlings.
