Tips to Successful Betta Breeding

So you want to start breeding bettas. Its not that hard if you follow these steps accordingly to raise beautiful and healthy bettas :

STEP 1: Conditioning a pair for spawning
When conditioning a pair, feed a variety of foods,many live and frozen foods. Every day, or every other day, water changes in the container are a must, as more and better foods together with lots of clean water, helps to get a pair into condition to spawn. Condition a pair for no less than a week, two weeks or more if they have just recently arrived via a shipment, or if they come from a pet store-the fish may have suffered from a lack of clean water and good food.

STEP 2: Setting Up the Spawning Tank
To set up a spawning tank, in my opinion, a ten gallon tank is the best. I have spawned fish in from a 2.5 gallon to a 20 gallon, but the 10 gallon with 3 inches of water works best. You’ll need a tank, a 50W submersible heater (anything larger may cook them!), a sponge filter (turned off during the actual spawning process) and lots of plants. You may use either live or plastic plants, but live plants work better. They keep the water cleaner while the filter is turned off, as well as culturing infusoria to serve as the first food for the fry. I use Java Moss and find it works the best for hiding, and the density is perfect. For a bubble-nest site, a styrofoam cup cut in half (resembling an airplane hangar) works well. You need a tightly sealing lid for the top of the tank, as betta fry need the air and water temperatures to be the same in order to properly develop the Labyrinth organ (common to the family Anabantidae). Set the heater to 80 degrees--no more, no less. Start this process about a week before the proposed spawn date in order to balance and stabilize the temperature. The pH and water hardness are not really critical to bettas, just the temperature. Have a container ( such as a glass lantern chimney) to put the female in, so that the male can see her, but can’t get at her. Place this near the spawn site, but not touching the syrofoam nest site.

STEP 3: Introducing the pair to the spawning tank
Place the male in a small cup of water and float him in the spawning tank 1/2 hour ( after the first fifteen minutes, dump out half of the betta’s water, replacing with water from the spawning tank). At the end of the 1/2 hour, dump the male into the tank. Then add the female in the same fashion, after first being sure that her container is closed so that the male can’t tip it over in his excitement. When her 1/2 hour has elapsed, place her into the glass enclosure where she will remain until she is released for spawning.

STEP 4: Releasing the female
Releasing the female from the glass encosure too early may cause undue damage, so be patient at this stage. There are four main signs that will help you determine if the female is ready to spawn. #1: The female, when ready, will no longer be scaed of the male, but be more inclined to swim with him and even flare back. #2: Look at the female’s stomach--females always carry eggs, but when ready to spawn, she will fill up hugely enough to look like she swallowed a marble. #3: The female will show vertical bars on the body indicating readiness to spawn, as opposed to the horizontal bars associated with fear or stress. This sign is not the most accurate as pastel or opaque females don’t show any sort of bars. This sign should only be used in combination with #1 & # 4.

Sign #4: The last sign to indicate a female ‘s readiness to spawn is that she will clamp her fins and swim with her body slanted forward and will exhibit the vertical barring and she will be doing a wiggling dance. (I don’t know what it is, but its true.)

STEP 5: Spawning process
When a female is showing three or all of the signs, she is ready to be released. You can carefully take her out of the enclosure and place her away from the male in the tank. She will swim around and when the male sees her, he will flare at her and chase her around the tank. There will be some nipping of the fins: this is normal. It is pretty, but that’s nature! Hopefully, at this point, he will have a well-built sturdy nest. If not, don’t worry, I have had males spawn and protect the eggs/fry without a single bubble. The female will come out once in a while from hiding to inspect the nest. If it isn’t to her liking, she will bite at it and jump at it, destroying it. He will chase her into hiding again and resume building. Once she approves the nest, she will come out doing the head-down dance, and will approach the underside of the nest. They will start the embrace. They will coma at each other and circle. The male will grip her with his body and flip her upside down while wiggling and squirming. He will then tighten and go almost lifeless, at which time she releases the eggs while he releases the sperm. The embrace will last for 10 to 20 seconds. Then the male will “come to”. and collect the eggs while coating them with saliva, to spit into the nest. They will continue this process ofr 1 - 3 hours, although I have had a spawn last for 5 hours. After they are done, he will chase the female away and you can remove her an her enclosure. Sometimes, they don’t spawn the first day, and you’ll need to put her back into her enclosure for the night, or she may seek revenge on the male.

STEP 6: Daddy duties
Once spawning is complete, and the female is safely removed, the male will guard the nest and any eggs that fall out will be put back into the nest. You need to leave a light on the tank (or nearby) so that he can see the eggs that may fall at night. After 2-3 days, the eggs will hatch and tiny (very tiny!) fry can be seen hanging from the nest. Now his job gets much harder, as the fry wiggle and fall out of the nest more frequently and the male has to keep up with them. In about 2-3 more days, the fry will begin to swim on their own horizontally. Now you can remove the male--his job is done.

STEP 7: Raising the fry
Once the fry are free-swimming, they need to eat lots of tiny food particles. They won’t usually eat for the first 5-6 days after hatching, but then you can feed live food and small flakes or pellets. “Liqui-fry for egg-layers” works great, as do micro-worms and vinegar eels. Now the filter may be turned back on (at a low rate). Keep the temperature at 80 degrees and leave the lid on the tank as warmth is crucial to the fry developing properly. Water changes may be started 2 weeks after they are free-swimming, after they are strong enough to swim away from the siphon. Keep this up for 2-3 months, when the young males willstart to develop their characteristics--fins will elongate, aggression will increase. When the fish are 3-4 months old, wean them to frozen food & pelleted diet.

That’s all it takes to raise them. It may look complicated, but once you get the hang of it, its both fun and enjoyable. You can then sit back and say,” For the past 3 months or so, that’s what I have to show for my work!”, and its very pleasurable.
