Betta Fish Breeding Quick Guide

Due to the unique character of the antagonistic fish and their large colorful fins, it is a challenge to try to breed Betta fish in an artificial habitat.

If you want to succeed in multiplying this species on your own, here are some tried and useful betta fish breeding tips.

Set up a Fully Equipped Betta Fish Tank

Since these territorial fish tend to get aggressive with their same species,
especially with the same gender, you must set up a permanent tank to keep them
apart and prevent them from killing each other.

The ideal pieces of equipment for a proper betta fish tank are :

  • Two 5 to 10-gallon tank with lid for enough space to hide, but not too big
    so they can't find each other. A 25-watt water heater that keeps a stable
    temperature similar to their natural habitat
  • Sponge filter to keep the water clean. Make sure that the sponge doesn’t
    create too much current to scatter the eggs
  • Air pump to draw water into the sponge filter
  • Some plastic wrap or styrofoam to create humidity
  • Add natural-looking moss and ferns to provide hiding areas
  • Insert removable tank divider to prevent the pair from fighting and to risk
    their lives.

Choosing the Beta Fish Breeding Pair

This is the most crucial part of successfully breeding a couple of betta fish.

  • Buy from a reputable breeder instead of a pet store even if they are more
    expensive because breeders have better information about the age and
    genetics of the fish. They select and maintain quality for themselves as
    well as the customers.
  • Choose a pair between the age of 4 to 12 months. Bettas reproduce better
    fry when they are young. Older betas often produce genetically weak and
    sickly breeds.
  • Since you will need at least a month to get them acquainted to each other
    and their environment, consider their age before you pair them.
  • Determining which betta to pick is another tricky challenge since the
    males are aggressive and the females are picky about their territory and

    Choosing the Perfect Breeding Pair

  • The female betta spies on the males to determine their suitability before
    mating with them. This is because they have instincts to sense the best
  • Like the female bettas, carefully observe the fish before you select them.
    Some points to look out for a while you pick the right betta pair:
  • Level of Movement: an active and energetic fish is a sign of good health.
    Slow moving ones that are barely affected by sudden movement show
    signs of parasitic infections or other diseases. It could also mean that they
    have genetically transferrable poor immunity.
  • Colors: Bettas are known for their colorful body and fins. Not only
    does the tone determine the quality of the breed but they are also
    indicators of good health and genetics.
  • The female mating preference determined that red-colored males are
    more attractive to the females than the blue.
  • Red pigment is an indication of sufficient carotenoids in the body which
    signals the female that the male is a successful forager and has a healthy
    immune system, therefore, makes a better mate.
  • Healthy Fins: Healthy male foragers have smooth and long fins without
    scars or damage. A female is likely to pursue one without tainted fins
    because it indicates that the male is a good fighter.

    Creating Breeding Conditions

    After you have built a suitable ground for each betta to swim and explore its
    surroundings, the next essential step is to create a condition for breeding.

  • Start by feeding them live food such as brine shrimps, bloodworms,
    roaches, and insects. If live food is unavailable, frozen food and freshly
    killed insects can also be used as substitutes.
  • Live food should be fed for at least a week before introducing the bettas
    so that they are familiar with their food and the conditions when they
  • After a week of live feeding the male and female in separate tanks, bring
    the containers closer to each other, so each fish has a clear view of the

    Betta Fish Breeding Signs to Look For

  • Make sure that they see and are aware of the other’s presence before
    putting them together to prevent injuries.
  • To find out if the fish are showing signs of readiness to breed, there are
    several signals you can see:

    Indications from the male:
  • Flaring of the fins,
  • Making a nest and
  • Imitating the female’s position and rhythm.

    Indications from the female:
  • Visible white egg tube behind the ventral fin
  • The appearance of vertical stripes on the body
  • May imitate the male’s movement
  • Moves with head held downwards

    Introducing the Betta Fish for Pairing

  • Remove the separator when you see that the male has built a bubble nest.
  • Let the female swim freely to the male’s territory in the breeding tank and
    keep an eye for signs of hostility.
  • Nibbling each other and chasing around is a typical trait that lasts for
    several hours to over a week so do not panic.
  • Ensure that there are plenty of places for the female to hide in case there
    is a threat.
  • Watch out for signs of injuries whenever you feed them and check them
    regularly for normal signs of energy level and healthy coloration.
  • If the female destroys the bubble nest, remove her from the male and
    restart the conditioning process and then reintroduce them.
  • If that happens again, your pair might not be compatible.

    Letting the Betta Fish Mate

  • Once the fish are comfortable with each other and their environment, the
    female will allow the male to catch her.
  • The male betta wraps its body around the female and strives to fertilize
    until the female starts to drop eggs.
  • Once the female release its eggs, the male collects and places them on the
    bubble nest that it built.
  • If you notice that the female is trying to eat the eggs, which is normal,
    remove her from the breeding tank.
  • Sometimes the female betta also helps the male to nestle the eggs so make
    sure you know what they are doing before removing it and placing her to
    her original tank.

    Caring for the Betta Fish Fry

  • The males should be left in the breeding tank along with the eggs and fed
    small portions on alternate days.
  • It might not want to eat as frequently so make sure you remove leftover
    food from the tank without disrupting the eggs before feeding fresh food
    stock to the male.
  • Keep the tank light on throughout the day and night
  • Keep the filter off to avoid the current from disrupting the fry.
  • After the fry loses their yolk sac, and they can swim on their own, you can
    relax a bit.
  • Feed them infusoria, baby shrimps, microworms and vinegar eels after a
    few days.
  • The water tank should be kept clean and frequently changed at least twice
    a week for the first two weeks, and the temperature should remain
  • Once the fry swims horizontally, remove the father into another tank and
    watch the fry grow into beautiful fish within a few weeks!
