Breeding the dwarf gourami

The male builds a bubble nest at the surface, often with bits of plant, and guards it. A spawn can be up to about 600-700 eggs, which usually hatch within about 36 hours.

Step by step

Pairing

Buy a young group and pick a calm male and a plump female. Condition with live foods.

Breeding tank

A 10-20 gallon (40-75 L) tank, 27-28 C, low water level, lots of floating plants and a lid. Keep humid air above the water.

What starts it

Warm water, floating plants and good food. The male builds a bubble nest.

Eggs and young

300-600 eggs; they hatch in 24-48 hours.

Raising the fry

Feed infusoria, then baby brine shrimp. Remove the female after spawning and the male when fry swim free. Keep the air above the water warm so the labyrinth organ develops.

Common mistakes
  • Cold air above the water, which harms fry
  • Leaving the female with an aggressive male
  • Using stock that carries Dwarf Gourami Iridovirus

Males are a little larger and much more colourful, with red and blue stripes and longer dorsal and anal fins. Females are silvery and plainer.

Can I breed it in my tank?

  • Good for a first breeding project.

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.

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