Betta fish was first reared in Thailand and was mostly found in rice paddies when compared to other aquarium fish’s.

The Betta fish does have some unique characteristics for example, their mode of breathing is via the labyrinth organ but that is not to say that they don’t use their gills. The fish is also very territorial and not afraid of challenges. 

When threatened the Betta fish will flare its fins, and this it does as a response to the threat. They also do act kind of jealous and will attack fish that have flowing fins like their own. When compared to the female betta fish, male bettas are more aggressive even to their won and you might find them attacking each other. 

The brightly colored betta fish have been produced via selective breeding and the original betta fish features a dull grayish to green color with short fins. We might not be able to provide information on the complex process of selective breeding but we will dig through the already selective bred brightly colored betta fish.

Interesting facts about the betta fish

I don’t know about you but the character of the betta fish closely resembles that of a dog. Betta fish has been known to recognize their keepers and will meet you at the glass window when you approach the aquarium. What’s more is that if you run your finger across the aquarium, they will follow it. Communication could be a challenge but the betta fish is a good entertainer because of its ability to perform tricks.

They are also in the habit of possessing all the eggs after they have been laid by the female and chases them away, that’s interesting. Let us, therefore, move to the primary purpose of this excerpt, which is to provide you with information on betta fish breeding. 

Breeding Betta fish guide

We all have better and decent ways that we would want to depart from this world, but certainly not by our own pee and poop. Now, why would you want your fish to be eliminated by its own pee and poop? A complete nitrogen cycle will ensure that ammonia has been converted to nitrite, and the nitrites converted to nitrates, which are not toxic. 

The above process helps in preparing the tank for breeding by eliminating toxins. 

1. Diet 

The diet of the betta fish has to contain all the necessary nutrients during the breeding period. Commercial pellets do contain most of the nutrients that the betta fish needs, but it is also necessary to supplement with other live food such as the blood worms. Other foods are the daphnia and brine shrimp. 

2. Eliminate chances of illness

Even human beings are not productive when they are sick, so strive to ensure that both the male and female betta fish are healthy before breeding. To this end ensure that the live foods that you feed the betta fish do not have some form of diseases. 

3. Type of tank 

Your betta fish is most likely cohabiting with fish of the same temperament in a community aquarium but please for the sake of the fry, find a breeding tank. This is especially necessary if you are really interested in breeding the betta fish exclusively for a purpose. There are so many reasons for this and one is because the Betta fish are very territorial and aggressive especially to their eggs, so we plan to avoid any instances o fights. 

The betta fry are fragile and will need regulated water conditions for them to thrive, this will however not last very long, because the male bettas only protect their young ones until they are able to swim on their own. 

4. Vegetation 

The betta fish breeding tank has to incorporate vegetation, if possible the floating plants, your tank should also have a filter, preferably a sponge filter that will prevent the fry and the betta eggs from being sucked up the filtration system. 


How to prepare the tank for breeding 

A betta fish tank should be filled with conditioned water so that your fish do not die or get diseases. Use a water heater to ensure that water temperatures don’t fluctuate. Also, invest in a water test kit that you can use to determine if your tank water requires any kind of treatment. The testing kits also offer solutions for any problems that your tank might be having, and you can thus treat your tank overnight.

1. Choosing the betta fish   

When choosing a mating pair, ensure that the male betta fish features long elaborate fins and are brightly colored. The pairing female betta fish also has to be healthy and strong 

2. Putting the fish in the tank

Life is actually very interesting as you will realize in a few seconds; apparently, when the female betta fish is attracted to its male counterpart, it will change its color and curve its body back and forth. The male on the other hand, when put in a tank with a female it will spread its fins and flare out its gills and just like the female it will start twisting its body. 

And here is the interesting part; betta fish have a unique breeding behavior, and you might be tempted to think that they are fighting. In case you notice the betta fish fighting during the breeding period just let them be because they are warming up for breeding. 

3. Bubble building 

The fighting of the betta fish is an indication that you have successfully selected a perfect mating pair. From then on the male betta will build a bubble nest at the surface of the water tank; it will then embrace the female so that it releases her eggs.  The male will then wrap itself around the female and with every embrace eggs will be released. 

The embracing stops when all the eggs have been released, while in the wild it is at this stage that the male betta will chase the female from the tank, but for your case, you could just remove the female from the tank, before it feeds on the eggs. 

4. Fertilization  

After removal of the female, the male betta will then fertilize the egg by releasing milk into the tank. After fertilization, the eggs usually begin to sink, but the male betta catches them using its mouth and takes them to the bubble nest. 

The male betta will then stay watch of the nest guarding it against external aggression. The eggs will hatch after 36 hours but the fry will remain in the nest for up to 3 days and absorb their yolk sac. When fully absorbed the young bettas will begin to swim on their own. 

5. Remove the male betta 

When the young fish can swim on their own while in the wild, the male betta would normally go its way, the reason why you should remove the male betta from the breeding tank. And after 3 to 6 weeks the betta young ones will begin to search for cleaner oxygen from the surface of the tank.
