Spawning your betta fish is a very exciting part of keeping bettas. Bettas lay eggs and also spawn ~ above a an extremely unique and interesting way. Obtaining a succesful generate is the beginning of her betta reproduction adventure, therefore a an excellent preparation payment off. 

If she planning on spawning her betta fish, you can wonder how to know when your spawn is successful, what betta fish eggs look favor or how countless eggs her bettas lay.

You are watching: How long does it take for fish eggs to hatch


Betta fish egg are little 1mm large and white balls. The eggs space not all completely round, but an oval unlike form. Eggs of mouthbrooding betta fish room bigger, roughly 2-3mm big and take much longer to hatch. during the development of the eggs, they will certainly swallow a little and turn much more yellow.

The hatching time the the eggs counts on plenty of factors. On average, that takes approximately 2-3 days because that eggs to hatch. The egg of mouthbrooder bettas take much longer, up to a month.

After this, the fry will start eating from their yolk sack and are still fully dependent top top the care of their father. The fry can’t swim, and also when they fall out that the nest the father picks them up and also places them ago in. After one more 2-3 work the fry have the right to swim and also becom independant.

How rapid precisily her eggs hatch counts on assorted factors, such as:


Because the eggs develop totally in the water, they room dependent ~ above the setting they build in to flower properly. Since the line is greater and cradle goes much faster in greater temperatures, it has a large effect ~ above how quick your eggs will hatch. Egg in a 75°F+ environment can flower in 24 hours, while egg in cooler temperatures can take much more than 3 days come hatch. 

In a current study around the link between water temperature and the hatching price of eggs of Channa striata, the outcomes were quite clear. The greater the temperature went, the quicker the hatching procedure went. It also had a large impact top top the survival and also hatching rate of the fry and also eggs. Although the eggs hatched quicker at 30-34°C, the hatch and normality price declined. Around 28°C seemed to it is in the sweet spot, with greatest factors. 

Altough Channa fish no betta fish, this research insinuates the result of temperature ~ above betta fish eggs, who space actually comparable to Channa in terms of habitat and genetics.

I discover the finest temperature for betta fish breeding and raiding is in in between 26(79) and also 28(82°F) °C. This means you have fast growth and also a high survive rate. It no recommended to save your adult bettas in ~ this temperature, due to the fact that they die faster in warmer water.


It is pretty obvious that the water quality has a drastic impact on how fast your betta egg hatch, and a drastic result on the flower rate. A poor water high quality could result in a component of your eggs or fry dying turn off fast, or in extreme instances they could all die.

If your water has too much organic waste produced by poop that the fish / bacteria if your organic balance isn’t right, ammonia levels will certainly rise, i m sorry are an extremely harmful to fish. Apart native ammonia there are miscellaneous other harmful substances and metals. If her tank isn’t clean enough, or you no cycle her tank, these may damage your vulnerable eggs and fry.

Luckily, the possibility your tank build up harmful amounts of any kind of chemical is pretty little and if you use the water in various other tanks effectively you shouldn’t worry around this too much.

Make certain to constantly do a water adjust before spawning, placed some catappa leaves and maybe a sponge filter in her tank. This method the threat of harmful chemicals being released is reduced.


Different Betta types have different hatching times because that the eggs. Bubble-nesting betta fish eggs hatch really fast contrasted to other mouthbrooding species. For part betta species such as Betta macrostoma eggs have the right to take longer than a month to hatch and free-swim! The average time for many mouthbrooding species is approximately 10-14 days.


If your egg is contempt growing and showing gray spots, you deserve to be certain the egg is fertile. Close to flower you could also see a little fish in the egg, through a white yolk sack.

Spawning your bettas no a guarantee the you will gain fry the end of it. Sometimes the male or female space not fertile, or her pair just isn’t experienced enough, which will result in a part of the eggs no being fertile. It is rare that all eggs in a spawn are fertilized and in some situations no eggs room fertilized at all. This is most most likely a sign that one or both of the parents are infertile.

The male will eat infertile or damages eggs and only care for abundant fry. In some cases, inexperienced males deserve to eat every eggs i m sorry is normal. By offering your male sufficient rest in a for sure environment, the possibility to a stressed male and also the masculine eating the fry/eggs decreases. 


The typical amount of egg betta fish have per batch is between 30 and also 100 eggs, but females can lay as much as 400 egg in a batch. Mouthbrooding bettas lay means less eggs, mostly in between 10 and 20 a batch, because the male hatches lock in his mouth.

The lot of eggs her female betta lays counts on numerous factors:


The size/age that the female

Betta fish sexually maturation at an age of 2-3 months, however I advise against breeding at together a young age. The takes a many energy and is much more risky because that a tiny female to spawn. The ideal is come wait till your woman is full grown and around the very same size that the male, return she will commonly be rather smaller. 

If the woman is too huge for the male, he can have a difficult time clamping approximately the female as soon as spawning and pushing the eggs out and fertilizing them. 

Small females will certainly lay method less egg than huge and enlarge females, because they don’t have actually the volume to carry and make all the eggs and also need come invest power in growth. I uncover the age females room most abundant is approximately one year old. Period is an additional to the size, if your 3 month old female already is full-grown the is safer and much more healthy. The same uses to enlarge females that are smaller. 

I discover the finest age to spawn is approximately 8 months to a year. Mine females space full-grown at an age of approximately 6 months, so this is the perfect time come spawn. At this age you recognize the full grown dimension of your betta female and that she matured sufficient to develop healthy eggs and also can manage the male.

Females stay abundant for their whole life, yet when they become older over 2-3 years, they will certainly start ending up being less fertile and producing less eggs.


Conditioning the the female

One of the most usual reasons for small spawns is that the female isn’t conditioned enough prior to spawning. During the air conditioning of your betta pair, the pair create a will to spawn, and the female will start producing lots that eggs. The much better you condition your pair, the greater chance that success will certainly be, and the more eggs a pair can produce. 

If you have conditioned for an ext than two weeks, girlfriend can try spawning the pair. Never shot spawning a pair without conditioning in ~ all, due to the fact that the pair needs to be all set for spawning. You can experiment with how much air conditioning you give, since I nothing think anyone is waiting for numerous bettas hatching.

Conditioning can be done by feeding the pair multiple time a day through high protein live and also frozen foods. Regularly show the pair come each other to encourage breeding behaviour and egg production.

Although bettas have the right to lay a the majority of eggs, it is rare that thousands of eggs will hatch and also become healthy and balanced fry. If the spawn is big, the masculine will generally eat a part of them, come make sure he can provide the finest care come the remainder of the fry. If your male is no so experienced, yes sir a an excellent chance a lot will be unfertilized, i beg your pardon he will certainly eat.

However that is no guarantee the you will have bigger spawns or a 100% success rate, the chance increases vastly.


Experience that the female

More proficient females ‘know the drill’ the spawning and if you have actually a female that has spawned multiple time it’s most likely that she will produce much more eggs. As soon as both your male and female space experienced, there is a bigger opportunity to more fertilized eggs and also a higher survival price of the eggs and new-bourn fry.


Bettas do bubble nests as a component of their breeding behaviour. The male builds the colony to administer a safe environment for the eggs and fry. When the pair spawns, the male places the eggs in the bubbles and will treatment for the newly-hatched fry and the eggs. 

In the wild bettas live in often oxygen arm and also shallow pools. The small bubbles administer a steady environment with enough oxygen at the water surface to defend the fried food in the most delicate days of their lives. It provides a hold-one for the tiny fry which can not swim yet.

Betta fish breathe using their labyrinth organ, i beg your pardon they likewise use to construct bubble nests. The males will certainly blow provided air to the surface. Your favorite spots room covered in tree or leaves. Building a nest under a leaf or branch offers extra cover and less danger for the colony to be destroyed. 


Although many world only recognize the Betta splendens, over there are loads of other betta types around too, which are not all the very same in terms of reproduction behaviour. 

Not every circumstances permit betta fish to produce bubble nests. Bubble swarms are very fragile and are only suitable for shallow pools through no current and also lots of natural cover at the surface. This is why types such as Betta macrostoma or Betta channoides don’t develop bubble nests, however will use their mouth to flower fry.

Mouthbrooding bettas greatly live in Indonesia, top top the island the Borneo, Sumatra and also Java. These habitats are different from those that bubble-nesters and also are streams / pools the usually have actually some type of current in them and also have much less cover at the surface.

This makes building bubble swarms not possible, therefore they have occurred a means hatching the eggs in your mouth.

If you compare your mouth to the mouth that a bubble-nester, girlfriend can clearly see the they have actually bigger jaws and bigger mouths. This is due to the fact that the male requirements to organize the eggs and fry in his mouth for multiple weeks before hatching. 

Hatching the egg in their offers them some serious benefits together as:

The male is able to guard the offspring every time and can acquire away without leaving the eggs /fry. Bubble-nesters have the right to never leave their nest.The eggs space in a more protected environment, and also experience great cover in the male’s mouth.There’s always enough oxygen flowing v the gills and also mouth i beg your pardon is beneficial for the breakthrough of the eggs and fry.

But there space some disadvantages because that mouth-brooders too:

The masculine can’t eat as soon as caring because that the fryThe male is an ext vulnerable for predators because he tote a serious burden through the offspring in his mouth.They can have much less eggs since the limited room in the mouthThe egg hatch slower because they are bigger.

Thinking about breeding your betta fish? acquiring the egg is a an extremely exciting part of your breeding journey. If your betta fish spawned succesfully, you will certainly see tiny white balls in the colony of the male. However keep in mind the your betta pair can develop over 400 babies, so be all set to raise up a most fry! The fertilized eggs will certainly hatch after ~ a couple of days and the fry will certainly hang approximately a pair of days before spawning. 

Mouthbrooders room different and have enlarge eggs, the hatch slower. If you aren’t prepared for numerous babies, wild betta moutbrooding varieties are a better choice and also will have less 보다 20 babies usually.
