Breeding Betta Fish

Betta fish breed most successful before they reach a year of age. (Bettas are usually bred between 6 months and 1 year) They breed in bubblenests and do not require a special  tank ( a breeding tank is recommended however) or equipment. In fact the male Betta fish takes care of almost everything. Were that only true for the human species - um... wouldn't you agree Ladies?

A bare bottomed tank,  ten gallons or so is sufficient but, if need be,  you can get away with smaller tanks. However, you must condition the Betta fish before breeding. This is not complicated and simply involves introducing them and feeding your Bettas with live foods.

To introduce your Bettas place each fish in adjoining containers where they can see each other. (the male will usually say something like " So, you hang out here often"...)  Use either separate jars or a barrier so that they can not intermingle. This should last between 3 to 10 days depending on their state of readiness. Once introductions have been made you can place them in the breeding tank together.

The breeding tank should be about 5 inches deep. Place a large leaf or a piece of foam in it to aid the male in building the bubble nest.


Several readers have sent emails asking which fish should be bred and how to tell when the fish are ready. In general you should select a pair that has the color and shape that most appeals to you.  The male should always be larger than the female and you might want to choose one that has a great deal of energy with a vibrant color.  The male is ready as soon as he starts making his bubble nest. The female will have a distended stomach culminating at the ovipositor. (white egg spot protruding from her abdomen) You will also see verticle stripes on the females flanks when she is ready to spawn. (If the stripes are horizontal this is a sign of stress) The female is capable of holding upwards of 500 eggs.

Notice the White Egg Spot (Ovipositor)

You should test your water's acidity. Ideally you want a PH level of about 7.0. The temperature of the tank should be 23 C or slightly higher (80 F).

When ready to spawn, the male Betta will blow a bubble nest. (This should take 1 - 2 days) Be sure to provide the female Betta  with a place that she can hide in. (Placing plants in the tank will provide shelter) This is to protect her from the male who can become aggressive during the courtship period. ( Men... sheesh!!)

It is not unusual for the female Betta to lose a few scales or have her fins frayed during spawning. (poor dear) Spawning will cause both male and female Bettas to display intense colors and begin circling each other under the bubblenest.

Next, the female betta will turn over and the male Betta will  wrap himself around her as she expels the eggs. Don't be alarmed if at times the female gets lethargic and floats to the top, this is hard work for her and can be exhausting. The whole process will be repeated several times until the female has finished laying her eggs.The eggs are fertilized and will sink to the bottom of the tank.This is when the male Betta takes over. He will scoop up the eggs in his mouth and carry them into the bubble nest. The male will tend to the brood from here on.

You should remove the female as soon as the male drives her from the nest. (Do this carefully so you do not disturb the nest) The male can become quite  aggressive towards her as he tends his young. Any eggs that fall out of the nest will be put back by the male. Within a day or two the eggs will hatch  and you will see the fry hanging from the nest, tails pointed downward. The fry are fed, for the next day or two,  from their yolk sack. If the fry fall out of the nest during  this time the male Betta will continue to put them back in the nest. 

The fry will start to swim in 3 - 4 days. When the fry begin to swim freely, you should remove the male or he will begin to eat them. ( alas... it's a fish eat fish world) I digress...

Feed the fry twice daily. Use baby brine shrimp, daphnia or very fine baby food. You can use a Tetra dry mixture specifically designed for egglaying fish. Most pet shops carry frozen baby brine shrimp.

When the fry reach 2 weeks you can begin small water changes but do be careful as the fry are still very small.

Remember - do not overfeed your fish. The excess food will foul the water and can quickly prove lethal to the fry.

Please keep in mind that these are just guidelines for breeding your Betta fish.

If you are serious about wanting to breed your fish then you shoud really invest in a more intensive course and learn all the necessary tips and techniques. This is especially true if you want to sell your fish. There are not a lot of guides that specifically deal with breeding Betta Fish but I have found an excellent publication that is reasonably priced and deals exclusively with Betta breeding. For those who are interested in becoming a Betta breader you can find the link below.
