Before getting into the specifics of selecting and preparing your adult Bettas before breeding, let’s go over the main points of the procedure. The short answer to the question of how Betta fish reproduce is that they don’t. Bettas don’t even engage in sexual activity! Then, how do Bettas reproduce?
Bettas are sexually dimorphic. Each parent contributes 50% of the genetic material to the offspring and thus has two unique genders.
Bettas are a spawning type of fish; after laying their eggs, the females fertilize the eggs in the water with the help of the males. Female Bettas cannot procreate without recent touch with a fertile male because the eggs are fertilized outside female bodies, which prevents them from storing sperm.
To persuade female fish to mate with them, male Bettas construct bubble nests. Until just before the eggs hatch, the male Bettas care for the developing embryos.
However, once the fry is swimming freely, there is a chance that the male might eat them. For this reason, you should utilize a breeding tank rather than the male’s aquarium when breeding Bettas.
Life Cycle of Betta Fish
When a male and female fish mate, the life cycle of the Betta fish begins. Typically, the female will seek out the male while the male first shows no interest in her. The female would lay her eggs on the male’s tail when the male and female have already been linked up. After fertilizing the eggs, he would transfer them to a bubble nest. The male will rapidly seize the eggs as soon as they are laid and lodge them in a bubble nest.
The male builds a bubble nest, which is where the eggs are set. To keep the eggs safe from predators, the male will watch over the nest for roughly 50 hours. In most situations, the egg-laying process takes only a few minutes, but it occasionally takes hours. Up until hatching, the male will take better care of the egg and fry.
Before seeking a partner, a male Betta fish will first protect his area. He often accomplishes this by creating a bubble nest for his female mate. The method is mild since he won’t get aggressive toward the female until he is ready to mate.
Should You Start Breeding Bettas?
Even though they make excellent pets, Betta fish aren’t the simplest species to breed. Small errors that wouldn’t harm an adult fish could ruin a mating session or tank of vulnerable just hatched Betta fry. Breeding requires a month of planning and is tiring for the adults; it is best left to fish keepers.
Fishkeepers who are familiar with using testing kits to monitor the pH, ammonia, nitrites, nitrates, and overall hardness of the water in their tanks. Familiar with the procedure for setting up and cycling new Betta aquariums.
Fishkeepers have prior experience maintaining multiple aquariums simultaneously, especially concerning feeding live foods, checking the nitrogen cycle and water quality, maintaining the aquariums, and keeping records.
At the very least, you’ll need a tank for your male and a different tank for your female or sorority group. A special breeding tank is set up for the actual mating process and hatching of young. Have the physical space and financial resources to set up and maintain multiple habitats.
How To Set Up The Breeding Tank?
Breeding tanks are very basic aquariums with no substrate. Typically, they have a sponge filter or air stone, several floating plants like Java moss, and some hiding places for the female Betta and her young.
Here are some steps to set up your breeding tank:
- Put your 10-gallon aquarium in a quiet area away from lights, on a solid, aquarium-safe table or shelf.
- 3 to 5 inches of conditioned water should be combined (or toxin-free water from another healthy Betta tank to help jump-start the cycling process).
- Adjust the temperature to 80 °F and add an aquarium heater, tilting the tube to completely submerge the device.
- Place a sticker or temperature gauge on the tank, making sure the gauge is kept below the waterline.
- Set up your air stone or sponge filter and baffle in the aquarium, and use plastic tubing to link it to the air pump.
- Examine your tools, and if everything seems in order, plug in the heaters and air compressor. After running your heaters and filter for 24 hours, check the circulation and temperature to make sure they’re in the right range.
- Use artificial silk plants with a fine texture or certain floating plants, such as Java moss or moss balls (not the stiff plastic type).
- Float one or two Indian almond leaves in the tank to give your male a suitable location to create a bubble nest and to help condition the water. Styrofoam cups can also be cut in half and taped or floated to the tank’s side if you want to watch.
- To check on the cycling process’ progress after two weeks, check the water in the mating tank. If necessary, perform a 25% water change. Your mature Bettas should be able to breed in your breeding tank!
What Equipment, Supplies, And Setup Are Essential For Breeding Bettas?
Let’s look at the tools and materials you’ll need to breed Bettas:
- For the mature fish, there are two completely furnished and cycled tanks.
- A minimum of two Betta fish that has been trained for reproduction.
- Your breeding tank should be a 10-gallon aquarium that is empty but has a glass cover, a heater, a temperature gauge, and a sponge filter.
- Kit for evaluating pH, GH, ammonia, nitrite, and nitrate levels in the water.
- Styrofoam cup, java moss, Indian walnut leaves, and plastic wrap.
- A tall glass vase or jar (6 inches or more) or a partition for your mating tank.
- During water changes and maintenance, you need a bucket and a siphon with the pipe.
- Delicacies like brine shrimp, blood worms, and daphnia eggs are either fresh or frozen.

How To Choose Your Breeding Pair Of Betta Fish?
What qualities should a couple of Bettas have before you consider breeding them? One of the most crucial considerations is their age:
Bettas should be around 4 and 11 months old because fertility sharply declines after the first year.
Since there is little probability that Bettas older than 12 months can successfully reproduce, conditioning them is not worth the effort and time.
Additionally, you ought to pick fish with the qualities you’re after. Selecting adults with or carrying the Double-Moon trait is necessary if you wish to produce Double-Moon Bettas. I advise you to read about the genetics of Betta coloration and consult with knowledgeable Betta breeders because color can be a lot more challenging.
Furthermore, you can create hybrid fish by mating Betta splendens with a wild variety. This isn’t the best option for your first mating. Wild-type Bettas are frequently more violent than the fancy splendens, and it can be more difficult to control their mating tendencies.
How To Pick The Best Male And Female Betta For Breeding?
Compare the energy level, coloring, and overall health of each Betta in the store.
Choose Energetic And Active Bettas
Seek out fish that are active, vibrant, and enthusiastic! They ought to have a strong hunger, be observant of their surroundings, and be curious. Do not purchase Bettas that appear listless, boring, or uninterested in food. Avoid purchasing Bettas that are in poor condition or from a store where they are kept in dirty aquariums or tiny cups.
Look For The Brightest, Most Colorful Male Betta
The most attractive mating male you can find is still vital to choose, even if you’ll be training your Bettas more before mating. You’ll need to choose a guy who is particularly alluring to the ladies because, in the wild, the female Betta controls the mating process and chooses her ideal spouse!
Male fish with a deep, rich color have a higher likelihood of being healthy and parasite-free than fish with a light hue.
Focus on choosing girls for their level of energy and overall state rather than their colors since they are naturally less colorful than boys.
Female Bettas prefer male fish with deep, jewel-like tones with lighter or paler hues. There is some indication that female Bettas prefer males with red/orange pigment more than any other color.
Size, Body, And Fin Condition
You should choose male and female Bettas who are in ideal physical health, with no visible signs of missing scales or fungus. Their fins ought to be smooth, without any sharp edges or injuries, and they ought to be plump but not fat. Damaged fins may be an indication of a sick fish because healthy Bettas recover quickly.
It’s ideal to breed Bettas of the same size, so pick a female that is just a little bit smaller than your male Betta. Choosing a female who’s larger than your male is not a good idea, though, as this kind of coupling rarely succeeds.
How Do You Know When Your Betta Fish Are Ready To Mate?
Since the most obvious indicators won’t be apparent until the fish engage with one another in the breeding tank, there are no strict guidelines for determining when your Bettas are ready to mate, or when your man encounters a female or Betta rival.
Your male fish may try to chase or fight the other fish if he is ready to mate. He may also change color and flash his fins at them.
Some female Bettas are initially more reserved and may clamp their fins firmly against their bodies. After spending some time with the male in the breeding tank, they will frequently become friends.
The white dot that emerges near the ovipositor tube, which is behind the ventral fin, is the most blatant indicator of a responsive or gravid (egg-filled) female. While she is in her home tank, you should be able to notice this dot. But once she is in the breeding tank, it will be easier to observe.
When a receptive female encounters a potential mate, her color will likewise darken, and she will grow vertical lines or stripes on her abdomen. However, if the bars are horizontal, that is a hint that she is not yet ready to breed.
How To Breed Betta Fish Step-by-Step?
It’s time to mate your fish once your mature Bettas are ready and your reproductive tank is ready!
Step 1: Move The Female To The Breeding Tank
Use a tank divider to divide your breeding tank in half, or place an open-topped glass vase or jar inside the tank. Fill the water in the vase from the breeding tank and keep it vertically on the bottom of the tank so that the water levels are equal.
Gently remove your female Betta from the breeding tank and place her in the jar or on one half of the divider. Give her between 30 and 60 minutes to adjust.
Step 2: Introduce Your Male And Female Betta
Take your male Betta and put him in the center of the tank if you’re using the vase method. Otherwise, on the side of the divider opposite the female. Your female should be able to observe your male Betta but should not be able to interact with him.
Your male’s color should change as soon as he spots the female, and he’ll probably start blinking his fins and acting cocky to attract her. It’s very normal for him to nibble at the glass or barrier separating them; it also indicates his interest in her.
At this point, the female may not appear interested in the male, but she could respond to his advances by flashing or waving her tail or flaring her fins.
The color of your female should also darken. She should show the vertical (not horizontal! ) bars on her belly, and the egg spot should be visible below her ventral fins if she is ready to reproduce.
Step 3: Watch As The Male Builds A Bubble Nest
Your male Betta will start working on building his bubble nest in an hour or two. To impress your female Betta, he’ll spend a lot of time swimming between the egg and the divider/vase.
In the meantime, if you’re using a vase because the male needs between 12 and 24 hours to make his nest, you might need to put your female back in her tank. She can’t stay in a small area for too long.
Leave the female with the male for two to four hours, depending on the size of the container, and then let her go back to her tank until the nest is ready. Since it’s usually for fish to fast during mating, wait to feed either fish until it’s over.
Step 4: Get Ready To Mate Your Bettas!
When the nest is ready, the male and female betas should interact directly. If you’re utilizing the vase approach, put your female back in the vase and give her another 30 minutes to adjust.
Check the female’s responsiveness to your male Betta before eliminating the divider or releasing her from the vase. Has her color intensified and is her vertically barring pattern visible? Is she making overtures to your guy? If so, you can proceed to the following action!
If she is showing horizontal bars or holding her fins close to her body, or if the response is no, stop. She is not ready to mate. Give your current lady a few more conditioning weeks and try again, or start anew with a different conditioned woman. If your female Betta is not into your male, DO NOT PROCEED!
Step 4: Release Your Female Into The Breeding Tank And Cover it With Plastic Wrap.
To release your female into the tank with your male Betta, remove the divider or tilt the vase.
She’ll likely swim over to the bubble nest to take a look. She might swim away or destroy the nest if she’s not happy with it. If she ruins the nest, you must remove her and try the following day again. However, if she rejects the male’s nest twice, you should start over with a different pair of fish.
Your male will put on a show and start following her around the tank as soon as he notices that she is free in his tank. Keep a watch on things and rescue the female right away if you believe she is in any danger.
If everything appears to be going smoothly, cover the tank’s open top with plastic wrap to boost the humidity within. However, keep a watch on things and be ready to step in if your female becomes upset.
The male may bite at the female’s fins and chase her if she isn’t responding to him as he would like. This is typical mating behavior, but if your female fish hides from your male fish or refuses to contact at all, she is not ready. You should return her to her original tank and start over with another female.
Step 5: Breeding Your Bettas: Mating Dance And The Nuptial Embrace
For a few hours, your Bettas will swim, chase, and bite each other as your female gets ready to lay their eggs in the bubble nest. Your female may occasionally snooze in the Java Moss or behind the Moss Balls in the tank, so there must be lots of accessible hiding places for her.
They can complete the mating ritual and finish spawning in 2 to 12 hours. When your fish swim close to one another and flare their tails roughly every inch, you’ll know things are going well. The male Betta seeks to turn the female upside down as he wraps himself over her during the mating dance, so he may fertilize the eggs while she moves.
They begin another round once the guy eventually releases the female. Every time your female is “squeezed” in the male’s embrace, she will lay a few eggs. As females float on the surface and release their eggs, female Bettas frequently appear listless or even on the verge of passing out, but they should shortly recover.
It’s time to remove your female Betta and place her back in her home tank once your male stops attempting to mate. So, it can begin gathering eggs and returning them to the bubbles nest. Keep an eye on her and check out for illness symptoms because she will likely appear pretty ragged and may even have torn or shredded fins. Keep the male Betta in your breeding tank to the nest, and then re-cover the tank with plastic wrap to maintain a high level of humidity. This results in the development of the eggs.
Step 6: Watch The Male Care For The Embryos
The embryonic development and hatching of the fertilized eggs take about 3 days. Your male may construct a new nest and relocate the eggs during that period, or he may decide to leave them wherever they are while he fusses over them.
To lessen the likelihood that your man will nibble on the eggs during this time, it is advisable to have him fast. There is no reason to let food rot in the water. This could increase the toxin levels and harm the fry, as most male Bettas show little interest in eating.
Sometimes a first-time dad eats all the eggs. You’ll have to start over if that occurs, but most male Bettas get on by the second pairing and stop acting off. If you notice your guy eating one or two eggs, don’t panic. They will ordinarily consume eggs that haven’t been fertilized or aren’t developing properly.
Step 6: Hatching The Eggs
About three to four days after they are set, the eggs will hatch when they are at the proper stage of development. Since it won’t fully integrate into the fry’s abdomen for yet another 24 hours, you can still see the egg cell that has been feeding the growing embryos.
The fry is typically still at this stage, hanging at the water’s surface in the bubble nest with their tails facing downward. The Betta fry ingests the oxygen in the bubble nests throughout the following 36 hours. They sink to the ground as the nest collapses, then the male scoops them up.
When the fry starts swimming freely after 3 to 4 days of hatching, it’s time to put your male betta back in his home tank, so he can get some well-deserved rest and recovery. Raising the young Bettas until they are completely grown and ready for their new homes takes 3 to 4 months.
How Does Male Betta Fish Form The Bubble Nest?
Before mating with a female Betta fish, the male will create an egg nest out of saliva. This is to make sure the eggs are successfully and safely hatched.
To reduce the likelihood of threats and dangers, the bubble nest will float on top of the water, keeping the eggs off the bottom of the tank.
Additionally, male Betta fish have a substance in their saliva that aids in the hatching of the eggs and the release of the young fish from them.
How Do Betta Fish Mate If They Fight All the Time?
Although Betta fish are notorious for being hostile toward one another, this does not preclude them from reproducing.
By maintaining them in a separate, roomy aquarium with consistent resources, appropriate vegetation, and a barrier to maintain them apart, you can lessen this hostility.
The female abandons her lover after spawning and disappears among the vegetation. The female will then place her eggs in the bubble nest that the male has constructed.
You should return the eggs to the main aquarium as soon as the female Betta lays them.
The male will construct the bubble nest in the interim and take care of the eggs until they hatch. You can put your boy back in the aquarium once he has finished taking care of the eggs.
Is Your Betta Fish Pregnant?
If you have a female Betta fish, she could get pregnant quickly. However, pregnancy in the way that we typically conceive of the word does not occur in female Betta fish during pregnancy.
Like humans and mammals, Betta fish don’t give birth to live children. Betta fish will instead conceive and give birth to eggs as a result. Many fish specialists will use the term “spawning,” which refers to the process of releasing eggs.
Betta eggs aren’t fertilized when they are released until a male Betta fish fertilizes them. Until then, they will not develop into baby fish. Many individuals do not believe Betta females to genuinely be “pregnant” because fertilization occurs after eggs are laid.
How Can You Tell When a Betta Fish is Pregnant?
We will refer to a pregnant Betta as a fish that will soon lay eggs for clarity. The gravid condition is how Betta fish are most frequently referred to when they are carrying eggs.
White stripes on a Betta fish’s flanks and a noticeable white dot on her belly are the most typical indications that she is pregnant. The ovipositor, a small white dot, is the organ in charge of egg production.
In contrast to these white markings, your female Betta may also have a protruding tummy. Even while the fish can just be overweight or constipated that might be one of the symptoms. The rise in stomach size is yet another powerful signal of pregnancy.
How Do Betta Fish Have Babies?
To reproduce, Betta fish must use external fertilization. The female Betta will conceive eggs, which the male Betta will then remove. And fertilize in a bubble nest. This bubble nest is constructed especially for the reproduction procedure.
A male fish is ready to mate when he builds a bubble nest, which frequently results in the female fish becoming pregnant. The nest will form from the fertilized eggs after fertilization. The young, or “fry,” may be developing from tiny black specks into fully developed Betta young. Bettas typically lay 20 to 50 eggs per mating. However, they might produce as many as 500 eggs.
The home the male Betta has built occasionally does not make the female happy. She will demolish the nest if it does not meet her requirements, which will prevent the fertilization of her eggs. She will let the male Betta fish take her eggs if she likes her bubble nest.
Although it can be difficult, taking good care of your Betta is not impossible.
Frequently Asked Questions
How Often Do Female Bettas Lay Eggs?
All year long, Betta fish can reproduce and can lay an egg every two weeks.
Since females may generate eggs rather quickly after their previous batch, you can simply encourage your female to breed with some other mate when the phase of laying eggs is finished.
How Long Is a Female Betta Pregnant For?
The pregnancy phase of a female Betta lasts for a week to two weeks. However, if your fish is unable to mate, you can expand your time frame by a week or two.
How Much Time Does It Take to Mate in Betta Fish?
Betta fish mating can occur for a few hours or several days. While some of them can lay their eggs in as little as two to three hours, others can take days.
Can You Breed Different Types of Betta Fish?
Betta fish of wide distinct varieties, including delta, veil tail, crown tail, and half-moon varieties, is suitable to breed.
However, breeding Bettas with different species runs the risk of resulting in deformities such as undersized fins or anemic bodies.
Conclusion
As you can see, breeding Bettas requires extensive planning and preparation and is undoubtedly more difficult. Have you considered or attempted to breed Bettas yourself?
