Breeding the polystigma hap

Maternal mouthbrooder; the female carries the young in her mouth for two to three weeks before releasing them.

Step by step

Pairing

One male with 3-5 females in a large tank with open sand; males guard a sand scrape or cave.

Breeding tank

400+ L tank with a sand floor, rockwork with caves and open swimming space, hard alkaline water (pH 7.8-8.6) and strong filtration.

What starts it

Large water changes, varied protein foods and a dominant male displaying in a sand nest or cave.

Eggs and young

The female holds the brood for about two to three weeks.

Raising the fry

The female releases fry after about 3 weeks. Feed crushed flake and newly hatched brine shrimp; sort by size often as fry grow unevenly and larger siblings eat smaller ones.

Common mistakes
  • Tank too small for adults
  • Keeping with small fish that become food
  • Not sorting fry by size

Male or female

Adult males are larger than females and show stronger breeding colours.

Can I breed it in my tank?

  • Good for a first breeding project.

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.
