Betta fish breeding

The Betta is a freshwater fish that lives in environments between 24ºC and 30ºC although they adapt to somewhat colder climates without difficulty, for that reason we can classify them as cold-water fish since they do not need devices that provide heat and can survive properly inside our house.

Preparations and first impressions


Before starting the process, we must correctly identify each sex to avoid confrontations as it is an aggressive and territorial fish. If you are not sure which is your betta fish, discover in AnimalWised the types of betta splendors that exist and their morphology according to sex:


  • The male has more developed fins and is more colorful.


  • The female is more discreet but more robust and the end of her fin is straight while that of the male ends in a point.

To begin we will have a space of at least 25 x 35 cm with about 8 or 10 centimeters of water height. We will add some moss so that they can eat and make the nest, and for this, we can also leave a small container such as a plastic cup in the fish tank, although then they will make the nest where they want. The week before we recommend that you isolate them in an environment where they cannot observe other members of the same species and feed them if possible with live food.

The first thing you should know is that you will never bring a male and a female together in the aquarium without first meeting each other since the male would consider the female as an intruder and most likely would start a fight with serious consequences.

Separate the aquarium using plastic or glass so that they cannot touch each other but can be observed. If you do not have a suitable separator, you can create one yourself by cutting a plastic bottle in half and creating small holes for the water to filter from both fish. In this way, with the female using the same medium as that of the fish tank, the male will better perceive the hormones that she releases.


First, put the female in the container that you have made or in one of the two parts of the fish tank, then the male and finally cover the entire aquarium with a glass, plastic, etc.

The approach


The male will create a nest with the moss in some area (probably in the glass). Then we will observe that the female is receptive trying to get out of her environment and pushing with her head. It is time to let go.


At first, both will act slowly, and until a while, the male will not begin to actively search for the female. The Betta Fish will take it, forming a strong hug around our female with its body, which will last a few minutes until it makes her pregnant.

It will not take too long to lay the eggs and immediately afterward we will remove the female from the environment where both are since the male can become very aggressive. She will return to her fish tank without having any contact with other males.


Father Fish Betta’s care


The male will place the fertilized eggs in the nest created by him and the young will hang like threads from the nest vertically. The parent will make sure that they do not fall and if they do, he will return them to their initial place.

After about three days of spawning, the small Betta fish will already be swimming alone, it is then the moment in which we will separate the male from his young. The male has not eaten anything for all this time and his children could become possible victims. So that this does not happen we can put some mosquito larvae in a corner in the aquarium and in this way when it begins to eat, we will know that it is time to separate it.


After separating the male you must remember that we must not put the male and the female back together, each one will have their aquarium, we will never join different sexes without the proper prior procedure.

We recommend using your hand instead of the net because we could take some of the fries without wanting to.


Now it’s up to us

Both parents’ work is over and our shift begins:


  • Three days after the separation of the young and the father, we will begin to feed them with micro-worms that we will find in specialized fish stores. We can ask the expert what to use. The process will last 12 days.


  • From then on, the little Betta fish will already eat Artemia. The process takes 12 days again.


  • After finishing the diet with Artemia we will begin to give them Grindal, and from the 20th we will begin to observe that they begin to develop correctly.


  • After a month we can change the small Betta and move them to a larger aquarium where they receive sunlight.


  • Once fully developed we will begin to observe the first fights between the males that will undoubtedly affect the females. It is time to separate them into different aquariums.


If you do not know the foods that we have provided, you can consult online or in your usual store how to buy them. Find out more about the Betta fish feeding Betta fish or common diseases of Betta fish.


And so far the process of reproduction and breeding of the Betta fish. Good luck and patience to all who try and remember to apply the first step correctly so that the male does not attack the female.
