Betta Splendens Reproduction

The first thing we must do to try to reproduce this little Labyrinth in our aquarium is to acquire a male. When doing so, it is advisable not to rush and observe the specimen in depth. Especially in the fins that should not be frayed or folded. The body must be absent from any kind of suspicious stain of any infectious or bacterial problem.

Healthy Betta should show intense coloring with fins outstretched and no spots on the body.

The Betta suffer a lot during their commercializationsince they travel in very small bags and are later installed in stores in small “beteras” of a size not much larger. Therefore, it is advisable to be attentive and acquire our copy as soon as possible.

In these Beteras the males, although in individual deposits, can be seen which triggers them to show their extended fins in front of the potential opponent. This habit will allow us to observe them carefully.

The females, on the other hand, are usually found grouped in the same aquarium.Among all of them we can easily locate the dominant one that will be precisely the one that we must acquire to join with our gallant.

The females do not have the majestic hues of the males but even so we can clearly distinguish their position of dominance by the colors.

It is important that we also know that the life expectancy of the Betta is short.In nature it is usually a calendar year. In the aquarium it is usually a little longer but it is much shorter than that of other common species.

The reproduction of Betta splendens

We can raise an aquarium of reduced volume.A 28-litre urn with a heater and a filtering system that does not cause a large current will suffice.

The physical-chemical parameters should be around the following… neutral pH(7), gH hardness at 10 and temperature above 27ºC.

It is not necessary to decorate it. It will suffice to place some floating plants, especially Riccia fluitans, Salvinia whose leaves will be used to make the nest. This floating plant also serves to generate infusoria on which the young larvae will feed in their first stage.

The bottom of the aquarium should be free of gravel, which will make it easier for the male to search for the eggs.that will fall after being fertilized as well as the siphoning and cleaning of the aquarium.

After a period of strong feeding of the couple, which we can extend for a week, it is time to introduce them into the breeding aquarium.First the male and then the female that we will keep inside a glass jar. This strategy allows both to be accepted and premature rejection does not occur.

  • The transparent glass or plastic jar should rest on the bottom of the aquarium with its level surface in contact with atmospheric air. If it is a plastic glass we can perforate it so that the water is exchanged.

When the degree of excitement has reached its maximum level, it is time to take the female out of the jar.At this time the male will usually accept the female and begin courting her. In unison he will begin to build the bubble nest on the surface with the help of the floating plants. This nest is dome-shaped with a large number of bubbles at the bottom.

Once built, the male will try to induce the female to spawn. The male performs spiral movements around the female with whom he will end up joining the anal part. Once the eggs are fertilized, they fall to the bottom of the aquarium where they will be picked up and transferred to the nest by the male.

Once the laying process is over, it is advisable to remove the female.Males can become aggressive and cause serious injury to their mate.

The laying can reach 400 eggsthat will be attached to the nest. The male will constantly add bubbles to the nest to repair any breakage. This process lasts until the larvae hatch. Hatching usually occurs around 36 hours.

The larvae, after consuming the yolk sac, will leave the nest to look for their own food.. It is time to remove the male leaving the larvae alone. Special care must be taken when offering them food so as not to overdo it and contaminate the water.

Betta baby care

We must start feeding the little larvae with live food…artemia nauplio or microworms.

Food should be offered in small amounts several times a day.By feeding in small quantities, we will pollute the water less and achieve a higher level of development of the fry.

In large groups of fry it is normal for episodes of cannibalism to occur on weaker, disabled or smaller specimens.

The critical moment in its development is after 3 weeks when the organ called the Labyrinth begins to form.We must take extreme care to maintain a similar temperature between the water and the outside air. Significant differences in temperature can cause us to lose up to 80% of the offspring.

To avoid this difference in temperature, it is advisable that the aquarium is covered and the room where the aquarium is located is not cold. We must leave a hole in the lid for gas exchange. Some casualties are normal, but they won’t be as numerous.

Another problem with which the pups usually succumb is with the protozoa responsible for velvet disease.

Breeding of Betta splendens

After the first three months, the sexes are already distinguishable and we must begin to separate the juveniles.Until 6 months there is usually no problem of intolerance among males. If one of them is especially aggressive, it should be separated. After this period, the males must be placed individually and the females can be kept in

Causes of the non-breeding of the Betta

  • One of the two copies of the couple is not sexually mature
  • If you do not make the bubble nest, the male will not be ready for reproduction.
  • Reproduction will not take place if the female is not gravid.
  • In certain cases the male can eat the eggs
  • The temperature of the breeding tank is not suitable
  • Do not remove the male when the free-swimming phase of the larvae begins. At this time the male can take them as food.
  • On some occasions we can come across a sterile specimen
  • What I said earlier about the incorrect temperature during the generation phase of the maze
  • The breeding will not develop if we do not place floating plants or, where appropriate, a mop.
  • Breeding is difficult to occur and we take out the fry in the company of unsuitable tankmates.
