Betta brownorum Breeding Guide
Breeding Brown's Betta Betta brownorum: a tiny Coccina-group bubble-nester needing very soft acidic water, with sexing and fry care.
Overview
Betta brownorum is a tiny wild betta closely related to B. coccina. It is a bubble-nester in which the male constructs the nest, and it requires soft, acidic conditions matching its natural habitat. Successful breeding hinges on stable blackwater chemistry.
Sexing
Males are more colourful and develop longer fins than females as they mature, displaying a large iridescent green lateral blotch. Females are paler, with dark bars appearing on the flanks prior to spawning.
Breeding Setup
- Temperature: 24-30 C
- pH: 3.0-6.0
- Hardness: 18-90 ppm (soft, acidic water)
- Provide tubes, canisters or fine-leaved plants as nest sites
Soft, acidic conditions matching the natural habitat are required. The male constructs the nest first and will not tolerate the female nearby until it is complete.
Spawning Behavior & Trigger
Spawning occurs below the nest in an embrace where the male wraps around the female, releasing milt and eggs together. The male then takes the eggs to the nest.
Egg & Fry Care
A clutch of fewer than 20 eggs is typical, though broods of up to 50 are not uncommon. Eggs hatch in 24-48 hours and remain in the nest for a further 3-4 days while the yolk sac is absorbed, the male tending the nest throughout; adults typically do not eat the offspring. Fry are large enough to accept motile foods such as microworm and Artemia nauplii immediately, offered in small amounts 2-3 times daily.
Common Challenges
The species needs very soft, acidic water, and unstable chemistry is the most common cause of failure. Keeping the male undisturbed while he builds and tends the nest improves spawning success.
