Betta Spawn Log : BSL20180323 : HMPK Super Red (M) x HMPK Red Base (S)

While we can't get a pair of HMPK super red, the closet we can obtain is a female Betta with red base. We suspected both Bettas are siblings as we bought both at the same time from a local breeder.

Male: HMPK Super Red
Age: 3+ months
Temperaments: Aggressive.
Size: Small (3.0cm body only)
Grade: C

Nothing much we can say about this male, not the best body shape we've seen and it crooked a bit. But for the price we paid for, nothing to complain about.

Female: HMPK Red Base
Age: 3+ months
Temperaments: Aggressive.
Size: Small (2.5cm body only)
Grade: C

We've noticed the female Betta compared to other female we have, seemed a bit more aggressive than usual even though the body size was thinner but longer.

Log Notes
The male and female Bettas have arrived and as usual, the unpacking, acclimating, quarantining, and conditioning the pair in the breeding tank.

Mating was aggressive. Something new we observed when mating, the male Betta will bite and chase the female Betta during mating, even though it was successfully. This was repeated for several times and we concluded that both these Bettas were aggressive in their original nature (both were siblings and from the same spawn). The photo below shows that the female Betta with damaged fins due to the biting by the male Betta.

The female Betta was removed and put into quarantine tank for recovering. Meanwhile, the male Betta was busying making more bubbles. We also added some water flea for the male to eat.

We noticed the male was still hiding under the bubble nest but not making any new bubbles. To our surprised, there were less bubbles in the bubble nest and we suspected that the male Betta may have eaten these eggs. Or maybe the male Betta confused the water flea with the eggs? Or maybe the eggs were not fertilized properly? Perhaps feeding the male Betta during these period was not a good idea as it will ignore any foods.

The male Betta was making more bubbles and we saw one or two fry swimming vertically. Maybe there was still hope that some eggs finally hatched. We'll keep our finger crossed.

We found a few fry free swimming in the breeding tank but the number was quite low, roughly less than ten. Upon seeing that, Baby Brine Shrimp (BBS) was given to the fry. Let's hope that those ten will survive.

We've checked the breeding tank and found no surviving fry. Several white spots were found on the Operculum area and it's best to clean up the tank and quarantine the male Betta ASAP.


1/ When you bought a pair of male and female Betta at a unbelievable price, most likely the pair have been used for breeding. Hence, subsequent breeding will result in lower or no fry count. Always check with the seller whether the female Betta is still a "virgin" female.

2/ Leaving father with fry method doesn't have good fry surviving rate if the male Betta and water quality of the breeding tank was sub-par.
