EESDA Betta Breeding

To start off, I think I should identify with sexing bettas. Some might think that plakat (short fin) males are females. To prevent you from putting two males together and end up with massacre, I am going to give some tips to identify if your "female" is really a she.
1. ovipositor: this is a small salt-looking organ behind her belly, before the anal fin. Be warned though because some chubby males have a similar looking thing on some occasions.
2. triangular belly: the belly of a female is more of a triangular swelling compared to a stuffed male's round belly. Looking from above, the female is wider and still has a triangular outline. If you look at a male from above, the belly is circular and round while the rest of the body is streamlined.
3. generally short fins: female bettas have short fins, even shorter than plakat males. However, I have seen long-finned females lately.


Now, here are simple steps I do to breed my bettas:

1. Prepare a barebottomed 2.5gal tank*. Place a few live plants and a piece of styrofoam for a bubblenest anchor.

*I have spawned in bigger tanks (10gal+) and with a fine substrate but not quite as fine as sand.

Here are more common set-ups.

2. Add the conditioned male and female. Some would use a chimney to separate the pair first but I have long stopped using those. Just let them be together.

3. Wait. Check the pair occasionally to make sure that none get too hurt. Although the wife-beating is part of betta love, there is a point where a female betta is too abused. The breeder must use his personal discretion.

4. After 2 days to a week, the bettas would have spawned already. The spawning process involves the female approaching the male's bubblenest in a bowing, submissive way. The male tries to flip the female and wrap his body around her. The female will release her eggs and the male will fertilize them.
At this point, you will have eggs. Betta eggs look like small pieces of salt hanging on the bubblenest. Remove the female. The male will kill her if you don't. Trust me. I tried.

5. Wait. After 24-48 hours, the eggs would have hatched and you will have fry hanging vertically. Just let them be. Wait again.

6. 2-3 days from hatching, the fry will be free swimming. You can remove the male at this point or opt to keep him with the fry as this method in these links:

7. If you opt to remove the male, use a coarse net to avoid taking any fry. When you catch the male, do not remove him immediately. Just dangle the net in the spawning tank for around 10 minutes. This will allow the male to spit out any fry in his mouth.


So there you have it. Betta breeding is easy. It might be tricky at the start but when you get the hang of it, it will be a breeze. Good luck on your spawns!

UPDATE (11/04/2013):
What I forgot to add in this post are tips!

1. Aggressive breeder = more volume, example: add water to a half-filled tank
2. "Too Battered" breeder = depends on you...if you think they will spawn, add more water; but if you think otherwise, scratch the pair
3. "Not Aggressive Enough" breeder = less volume, example: drain water to half level
4. Short-finned male = more volume
5. Long-finned male = less volume
6. Female is larger than male = more volume
7. Male is much larger than female = more volume
8. No bubblenest = normally, I let the pair be...this type of male builds a small one after he squeezes the female; but other times, I scratch the pair
9. Female is not moving anymore = separate the female, out of other fish's sight...if she swims fine/properly/upright, put her back in; but if she doesn't, scratch the pair
10. Judgement and gut feel and intuition = breeders develop some kind of instinct as they breed more fish; trust your self!
