Breeding the brownorum betta

Bubble-nester, not a mouthbrooder. The male builds a nest in a tube, under a leaf or among floating plants, and alone guards it; adults usually do not eat the fry, which take microworm and Artemia nauplii once free-swimming.

Step by step

Pairing

A conditioned pair.

Breeding tank

40 L soft acidic planted tank with caves.

What starts it

Soft acidic water and live foods.

Eggs and young

Usually fewer than 20 eggs, sometimes up to 50. Eggs hatch in 24-48 hours and stay in the nest 3-4 more days.

Raising the fry

Fry take baby brine shrimp from day 1.

Common mistakes
  • Hard water
  • Boisterous tankmates

Male or female

Males are more colourful and develop longer fins than females; both sexes carry a large iridescent green blotch on the flank.

Can I breed it in my tank?

  • Takes some experience.

Day-by-day plan

Typical for bubble-nest builders

  1. 10 days beforeCondition and introduce

    Feed well, then let the female see the male through glass before putting them together.

  2. Day 0Spawning under the nest

    The male wraps the female and places eggs in the nest. Remove the female after spawning.

  3. Day 2Eggs hatch

    Eggs hatch in 24–48 hours. The male catches falling fry and returns them to the nest.

  4. Day 4Free swimming

    Remove the male. Feed infusoria and keep the air above the water warm and humid.

  5. Day 10Baby brine shrimp

    Move on to baby brine shrimp and microworms. Change small amounts of water daily.

  6. Day 56Separate males

    Males start fighting at about 8 weeks and need their own jars.

A general guide for this breeding type. Days change with temperature and species.

No spawning
  • Without live or frozen food the parents aren't in breeding condition.
