A captive breeding report in 2025 conducted by Priyadi et al. found the following information on
Betta hendra breeding: Conditioning adults for breeding consisted of daily live feedings for 30 days. Water temperature was kept between 28.0 - 28.6°C (82.5 - 83.5°F) and pH between 6.35 - 6.40. Males and females were kept separate at this time. After the 30 day period, the fish can be paired up, and within ~2 days,
Betta hendra males form bubble nests and spawn. Bubble nests are typically built under dried leaves or corners of the aquarium. After hatching, it takes ~4 days for the yolk sack to be fully absorbed, and for feeding to begin. Freshly hatched
Artemia are a highly recommended food source. After around 3 weeks, fry become independent from their father. Fry reared without males had a lower hatching rate with a higher survivability. Fry reared with males had a higher hatching rate with a lower survivability. == References ==
