Betta fish is attractive fish native to South Asia, commonly known as fighter fish/ fighting fish. It is popular due to its colorful morphological patterns. Let’s see how to breed betta fish.

01. Select The Best Breeding Pair

Before breeding them, think deeply about the breeding pair. Select a healthy and active male and female without having any disease symptoms. Strong and healthy fish is good for the breeding process. 

Health is not the only fact you should concern about; fins, colors and shapes need to be inspected. Beautiful fins are essential to bettas, then examine the fins of parents. Reject those who have abnormal or incomplete fins as features will pass to babies. Remember that good parent make good babies. 

A pure bloodline is always good for producing a new generation. Make sure to select breeding pairs of the same type unless crossbreeds give unnecessary things.

How to identify an egg-caring female 

Usually, egg-caring females are fat as bears eggs; if you see her belly area, a whitish sharp organ can be seen which means she is ready for breeding. It is essential to know that she is caring for eggs. If you add an unmatured female mistakenly, she can even die in mating due to stress.

Feed in the pre-breeding period

An important fact that people usually forget is pre-breeding feeding. Both males and females should be fed well before starting the breeding. Protein-rich foods encourage the egg development. Also, this period helps bettas to be strong; we can observe their color, fins and nature closely.

02. Tank Preparation 

Even a tiny tank or a tub is suitable for betta fish breeding, but use at least a 5 to 10 gallons glass tank. Usually, betta fish lives in fish bawls or small rounded containers. But when it comes to mating and breeding, a squared glass tank is essential.

The water should be dechlorinated. Fill the tank with treated water. The water level should be below 5 inches from the bottom. 

Betta fish require a 6.5 to 7.7 pH range. Monitor the pH range carefully and add a dried almond leave as a natural pH regulator. As betta is a tropical fish, a small aquarium heater is essential to maintain the temperature. Ammonia and Nitrite should be zero ppm.

Male betta fish creates a bubble nest on the water surface using his mouth. He places the eggs in a bubble nest after spawning. But an external aid is essential to gather the bubbles. A piece of banana leaves helps collect the bubbles and establish the bubble nest.

We don’t use much decorations and equipment in the breeding tank, but some aquatic plants are used.

03. Breeding Betta Fish

First, collect the male betta into the breeding tank. It’s better to do it in the morning time. Give a few hours to adapt to the new environment. The bubble nest is a significant creation in betta fish breeding. Male fish should create it, but he needs and sexual impression to create it. When he sees females, he is impressed sexually, Starts to build a bubble nest.

But we can’t collect females without having a bubble nest; the female should show to the male through polyethylene or glass. When he sees the female, he builds a bubble nest near the water’s surface. In the evening, collect the female also.

Read about the betta fish eggs 

Male fish start chasing around female; sometimes, the male can be aggressive. Usually, after one day, you can see eggs there. Once you see eggs, remove the female quickly because she might eat eggs. The male carries the eggs and pastes them into the bubble nest. Usually, he doesn’t eat eggs, but females do. Males should keep in the tank until babies come. 

After two days, small fish will arrive. They won’t eat until three days as they can feed by egg sack. After three days, chopped egg yolk should be provided for a few days.

In Breif: How To Breed Betta Fish

You’ll need a male and a female betta fish, a breeding tank or tub with a heater, a filter, and plants. First, Remember to condition the bettas with high-protein foods. Once they’re ready, introduce the male to the female and watch for courtship behaviors. Remove the female after the eggs are deposited. Keep the male to protect the eggs.

Feed the young frequently throughout the day with tiny portions of food after the eggs hatch.
