Breeding the brunei beauty

Paternal mouthbrooder: the male carries the eggs. Incubation reported as 14-35 days, after which the male releases free-swimming fry. Males often swallow broods if disturbed, so keep the tank quiet; the fry (5 mm+) take microworm and Artemia nauplii at once.

Step by step

Pairing

A well-fed pair in a roomy tank.

Breeding tank

100 L soft acidic tank with caves, leaf litter and plants.

What starts it

Soft acidic water and meaty foods.

Eggs and young

30-60 eggs carried by the male.

Raising the fry

Fry are large enough for baby brine shrimp, microworms and grindal worms.

Common mistakes
  • Housing males together
  • Small tankmates getting eaten

Male or female

Males grow larger, are more colourful (red), have a broader head and longer fins than females.

Can I breed it in my tank?

  • Takes some experience.

Day-by-day plan

Typical for mouthbrooders

  1. 21 days beforeGroup and condition

    Usually one male with several females. Feed high-quality food.

  2. Day 0Spawning

    The female takes the eggs into her mouth and stops eating.

  3. Day 21Release

    After about 3 weeks the female releases fully formed fry. Many breeders move her to a quiet tank first.

  4. Day 21First food

    Fry eat crushed flake and baby brine shrimp straight away.

  5. Day 90Grow-out

    Fry are a few centimetres long after about 3 months.

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