Fighter Fish have a fairly short life span, living on average between 2 to 5 years, so if you are planning on breeding them its best to do it while they are under a year old so you will yield the best offspring. Most of the Betta Fish that you will find in pet shops are typically about 6 months old.
Most breeders feel that a 10 gallon tank or bigger works great, just make sure its bare bottom so the Fighter Fish can make their little bubble nests with ease. You definitively want to avoid using any kind of pebbles in the tank when breeding as the eggs may end up falling through them and dying.
If you really wanna get some great offspring then you’ll need to precondition your Betta Fish for breeding by feeding them a ton of live food. The water should have a PH of exactly 7 and have a temperature no colder than 80ºF, you can got a few degrees hotter if you would live too.
Whats going to happen next is the male will blow an elaborate bubble nest, they look really cool. At this point you’ll need to create a little hiding place for the female as the males can get kinda aggressive when its time to mate. It’s actually not that uncommon for the female to loose a few scales or have a few nips taken out of her tail.
Just make sure that after the breeding session is over that you remove the female from the tank because the male Fighter Fish have been known to kill the female Betta while he is tending to the bubble nest.
When the pair is ready to spawn their colors will become extremely vibrant and the male Betta Fish will start to circle the female under the bubble nest. Then the male will wrap himself around the female after she has been flipped to her back. As she excretes the eggs they will become fertilized by the male and will begin to float to the bottom on the tank.
Next the male will gently scoop up the eggs and spit them into the bubble nest where they can finally hatch over the course of the next few days. From this point on the male Betta Fish will tend to the young and the female most definitively needs to be removed from the tank because this is when the male is most aggressive.
In the next few days the male Fighter Fish will continue to watch over the nest making sure to spit back in any eggs that fall out of the bubble nest, but in the next 2 or 3 days the eggs will hatch and the young fry will be swimming around the tank with Daddy. At this point, you’ve gotta remove the male fish because he might eat the young, and there goes your whole spawn.
Now that you’ve got an open tank, the fry should be fed a few times daily preferably with baby brine shrimp as they contain the best nutrients for the young broods. For the nest you should use some kind of Tetra mix as it does great for the bubble nests and resembles the Fighter Fish’s natural habitat. And take care about not over feeding the fry because if you do it will pollute the water.
If you follow all these basics tips you should be able to pull of a breeding successfully even if its your first time attempting it. I wish you the absolute best and if you have any questions or other breeding techniques then please leave me a comment below.
