Particularly in their early years, Betta tends to ask a lot of questions. The question of how long it takes to watch them grow is the one that comes up most frequently. Thankfully, years of practice allowed me to acquire some understanding of this subject.
Betta fry develops and matures to its maximum size during three to five months. They are now regarded as adults and have scales and fins that are completely developed. However, the Betta won’t mature sexually and begin breeding until it is seven months old.
I’ll go into more detail as we go along about how long it takes Betta fry to mature, along with a thorough breakdown of the various growth stages. Then, I’ll give you a few pointers that can help your Betta fry develop more quickly.
How Much Time Does Betta Fry Need to Grow?
The Betta’s fry will begin to grow rapidly as soon as they are born. In about seven months, the baby Betta fish will be fully grown and ready to mate with its partner. The Bettas will be between three and four inches long.
One of the species that thrive even in unfavorable water conditions is the Betta fish. This is because the fry might have trouble getting enough food and oxygen in the early stages of their lives.
When there are fries in the water, it is advised to control the bodies of water. They will adjust to the water conditions after three to four months in the tank, and their immune systems will guard them against infections.
What Are The Betta Fry Growth Stages?
Avoid the young Bettas if you plan to purchase them from a fish store. They are more challenging to examine because they lack the full range of important physical characteristics. Aim for at least seven weeks.
The following morphological and behavioral changes will occur in Bettas if you decide to breed and rear young in an aquarium at home.
Stage 1: Egg (Days 0-3)
The beginning is here. The female Betta produces the eggs and deposits them in the water for fertilization by the male Betta. The time it will take to complete a breeding cycle is unpredictable.
According to the condition of the matching pair and the amount of conditioning you completed, mating can last a few hours or several days.
Due to the unpleasant conditions in the tank, some female Bettas may choose not to release their eggs. The male Betta will, however, retain the eggs in a bubble nest before they hatch if mating is successful.
Within 36 hours, the white cluster of eggs should be visible. The eyes and tails of the fry are also visible in the developing eggs if you look closely.
More bubbles may be blown by the male Betta to protect the eggs, particularly if they begin to tumble from the nest. The eggs often hatch after up to 72 hours.
Stage 2: Newborn (Days 3-7)
Approximately two to three days after hatching, the Betta fry should appear. Expect not every egg to hatch because some may not be fertilized. The precise quantity will depend on elements like the tank’s conditions and the male Betta’s age.
Young guys who have never mated before are much more likely to perform the fertilization process ineffectively. For 24 hours after being born, the fry will remain near the nest. You can get rid of the male Betta after the young start to venture away from the nest.
Follow the cues from your observations. The newborns might need three or more days to learn how to swim horizontally. During this time, they will depend on the developing embryo.
Until they become strong enough to leave the nest on their own, the male Betta must remain in the tank to defend them.
Stage 3: Juvenile (Weeks 1-3)
When Betta fry leaves the nest, they are categorized as juveniles. They spend between two and three weeks in this period. During this time, its labyrinth organ will mature, enabling the fish to absorb oxygen from the surrounding air.
Your Betta fry will now start to swim horizontally as free swimmers. They may occasionally sink to the bottom of the tank, which is perfectly fine.
Stage 4: Young (Months 1-3)
Normally, at this stage, I advise purchasing Betta fish from the fish store. When they are 7 or 10 weeks old, wait. You will have a clearer understanding of the Betta fish’s characteristics, including not just its colors but also the size of its fins.
At this point, young Betta fish are unable to breed. Therefore, you don’t need to divide the male and female fish as yet if your goal is to prevent mating.
However, some individuals choose not to take any chances. When the fish develop their fins and colors, they will separate the Bettas into different aquariums.
It is now okay to separate your Betta fry if they were raised in a breeding tank. The males begin to pose a threat to one another around two months of age.
Stage 5: Adult (Month 3 And Onwards)
Due to their size, Betta fish are frequently categorized as adults at the age of seven months in fish retailers. However, for many aquarium hobbyists, the Betta’s size has little to do with adulthood.
Bettas will develop at varying rates. Some fish can develop to their full length over the year.
Experienced breeders prefer to connect sexual maturity with adulthood. In light of this, it is reasonable to consider a Betta fish to be an adult at the age of three to five months.
What Are The Betta Fry Size Changes?
Many aquarists don’t distinguish between a Betta’s many developmental stages. These people view Bettas as fry when they hatch, although they are sexually inexperienced, adults after six weeks.
However, even if you are unable to determine when a fry enters the juvenile stage, you could still note the following changes in the creature’s size throughout the first ten weeks:
- When they hatch, they are 0.1 inches.
- At two weeks, 0.25 inches.
- Four weeks later, 0.45 inches.
- After six weeks, 0.8 inches.
- Eight weeks later, 1.3 inches.
- Eleven weeks later, 1.5 inches.
Bettas often reach a length of 2.5 inches when fully grown. However, some fishkeepers have raised Bettas that are 3 inches long. Only because of their larger fins do the male Bettas appear larger.
What Are The Betta Fry Weight Changes?
The weight of a baby Betta varies from 0.02 to 0.05 grams. With the fish’s growth, that amount will increase to 3 or perhaps even 4 grams. The creature’s food, however, will determine its final weight.
The following alterations will be visible as the babies develop:
When the fry hatch, 0.01 to 0.02 grams.
- At one week, 0.03 grams.
- At one month, 0.05 grams.
- At 3.0 months later, 2.5 grams.
- At 4 months later, 3.0 grams.
- At 5. months later, 3.5 grams.
- At 6 months later, 4 grams.
Does Betta Fry Eat Different Foods As They Grow?
During the first 24 to 48 hours, you do not need to feed the infants. All the nutrition they require will be provided by the yolk sacs. Before feeding the infants, wait until they can swim unassisted.
- In week 1, they will consume nematodes and infusoria.
- In week two, add young brine shrimp to the diet.
- In weeks three or four, try larger items like bloodworms.
- Give their food some variety by including Grindal worms and blackworms. In weeks five or six, you can introduce frozen or freeze-dried foods.
At this period, the newborn Bettas can ingest dry pellets. By week 8 or 9, they can begin consuming the same meals as adult Bettas do.

At What Age Do Betta Fry Get Color?
Bettas are beautiful fish, Bettas. Aquarists have utilized selective breeding over the years to produce Bettas with amazingly bright colors. Thus, it is not too difficult to comprehend why colors are important to an aquarist.
You don’t want to introduce Bettas with unattractive hues and damage your aquarium. However, Betta fry is initially transparent. For the first few weeks, you cannot evaluate their color.
The critters’ hues don’t emerge until weeks eight or nine. However, even at that point, the hues might keep shifting until the fourth or fifth month.
The colors you see in a Betta’s first few weeks of existence should not be used to predict how the fish will look.
How To Make Betta Fry Grow Faster?
Properly treating the Betta fry would be the first stage in this process. You must feed young Betta fry around five times every day till the conclusion of their juvenile stage.
Researchers discovered that young fish exposed to more frequent feedings have a greater survival rate.
It is, therefore, preferable to treat your Betta fry in modest amounts several times during the day.
To find out what to feed Betta fry, refer to the guide I previously mentioned. In general, you should limit your diet to foods high in protein, such as infusoria or baby brine shrimp.
It’s also important to note that Betta fry creates a hormone known as GIRH (GIH). Or, to put it another way, a hormone that slows their growth.
I also advise you to adhere to the following water standards:
- Temperature: 29–31° C (85–88° F).
- pH: 7.0-7.2
- Hardness range: 2–20 dGH (70-300 ppm)
- The hardness of carbonates: 3-5 dKH (55- 90 ppm)
- 0 ppm ammonia
- 0 ppm of nitrites
- 20 ppm of nitrates
Your Betta fry will be stress-free, healthier, and more eager to eat if the water parameters are kept within the appropriate range.
I generally use the API Freshwater master test kit to test the pH, ammonium, nitrates, and nitrites. It is very cost-effective because it lasts for roughly 800 measures.
How Often Should You Feed A Baby Betta?
Feed a modest amount of food three to four times each day. The meager portion would allow the tiny Betta to correctly devour the food without destroying it once it reached the aquarium’s bottom.
How Frequently Should You Feed Baby Betta?
Most of the time, it is filtered out or lost. The young Betta would require more time to chew its meal before swallowing it. Therefore, feeding the young Betta every several hours will enable them to get the nutrition they require and maintain their health.
How To Feed Your Fry To Maximum Growth
Here are your step-by-step Betta fry feeding instructions in case you’re wondering which food should be given to your fish and in what order:
- You must only feed the Betta fry little foods for the first three days after they can swim freely. It contains microscopic free-living nematodes such as vinegar eels, microforms, banana worms, Walter worms as well as infusoria.
- You can begin feeding young brine shrimp after three days.
- You can keep feeding newborn brine shrimp after a week. But cease gifting nematodes because they will become less useful moving on (in terms of nutritional value.)
- Finely grated frozen items can be added to your fry’s diet together with brine shrimps in 3 to 4 weeks. Bloodworms and Daphnia should be used as a starting point. Bettas enjoy a wide variety of foods.
- You can begin feeding aquatic worms like blackworms and grindal worms after 4-5 weeks.
- When they are 8 to 9 weeks old, Betta fry is ready to eat and digest nearly any Betta meal you give them. Bloodworms, frozen foods, and dry feeds like flakes, pellets, and sticks may be included.
Does Betta Fry Need An Air Pump?
For the Betta fry, air pumps aren’t necessary. The fish doesn’t need an air pump to breathe in the water. To ensure that there is enough oxygen in the water for other marine life, the fish keeper utilizes the pump.
A significant amount of oxygen would be required for the plants in the tank to flourish. For proper growth, oxygen must be added to the water because while fish can travel to the source and take the oxygen from the air, plants cannot.
Can Betta Fry Live In Cold Water?
To a certain point, Betta fry would survive in the chilly water. After that, It will reduce the Betta fry’s movement. They’ll be stationary in the corner, where you’ll discover them.
They will struggle to muster the energy to move, let alone swim to the surface for oxygen.
The health of the Betta fry will be impacted because of the numerous diseases that the still motion will attract. In the worst-case scenario, Betta fish will quickly perish if the temperature is unsuitable. This is so because Betta fish like warm water to dwell in.
How To Change The Water For Fry Tanks Without Losing Any Fry?
Your grow-out tank can be cleaned out in a variety of ways. A quick “Search on youtube” will turn up a wide range of options.
A word of caution: Regardless of your preferred approach, avoid using a standard gravel siphon for this job. The small fry fish run the risk of being sucked out and dying.
We will need a toy mop and a ketchup dispenser to demonstrate to our readers how to safely drain water from the fry tank for this article.
It is a practical, simple-to-use tool that accomplishes the task with the least amount of effort.
- First, if you don’t already have one, make a tiny mop yourself. Look up videos online for how-to content.
- Remove the dirt that has gathered at the tank’s bottom and on its walls with your tiny mop. Do it carefully to avoid killing any of your fries.
- Grab your ketchup dispenser and start sucking in the dirt after you’ve finished mopping.
- Repeat the vacuuming procedure until the tank seems to be debris-free, then drain the unclean water into a different container.
- Lastly, top off your grow-out as needed using treated or aged water.
When To Separate Male Betta Fry?
At around nine to ten weeks old, juvenile males start to grow and turn hostile against their tankmates. Therefore, as soon as you notice the male Bettas biting on smaller fish, you must separate them.
It’s called “jarring” to separate the male fish fry. Every male needs a place to call home, which may be a jar, flask, cup, or another container.
Betta females can be transported in different containers as well. However, you can put them together in a tank if you don’t have enough room. However, you should be warned that larger fish would not spare the life of their younger siblings.
It could get fairly challenging, considering how many jars you have to manage, particularly if you are a novice breeder.
Frequently Asked Questions
How Long Can Betta Fry Live Together?
Betta fry can be kept in the same tank until you see aggressive behavior, which is frequent in fish 8 to 9 weeks old.
You should separate male and female fish when you witness them pursuing one another and engaging in combat with lesser fish.
How Long Does It Take Betta Fry To Hatch?
The eggs’ hatching time is influenced by several variables. The Betta eggs typically take two to three days to hatch.
What Age Do Betta Fry Get Colors?
By the time they are 8 to 9 weeks old, Bettas begin to develop their distinctive, brilliant colors. Based on the diet and aquarium conditions, your Betta fry might show colors before it should.
Does Betta Fry Need An Aerator?
You don’t need an aerator in your grow-out fry aquarium if your filter is agitating the water at least minimally.
Conclusion
The growth and development of Betta take about three months (about two and a half inches long). They are considered adults at this point and have scales and fins that are fully developed.
When they are between six and seven months old, they are sexually mature and capable of giving birth. Therefore, it is best to segregate the sexes at this time if you don’t want any more generations.
