Why keepers choose this species
The male builds a bubble nest and tends eggs, giving the keeper a clear view of courtship and parental behaviour.
Set up around the fish
Prepare a warm, covered, shallow breeding tank with calm surface water, hiding cover and no unsafe filter intake. Have containers or divided grow-out systems ready before spawning.
Spawning and parental behaviour
Condition and introduce fish cautiously, monitor continuously and separate them if aggression becomes damaging. The female usually requires removal after spawning; later the male is removed when fry become free-swimming.
Fry and grow-out
Very small fry require appropriately sized first foods and stable, clean air above warm water. Juveniles may need individual separation as aggression develops.
Important limit: A successful spawn can create more juveniles than expected. Do not breed without a credible plan for individual housing, heat, water changes and homes.
Before you start
- Confirm the exact species or strain and its adult care requirements.
- Prepare a cycled fry-safe filter and separate grow-out capacity.
- Arrange appropriate first foods before pairing adults.
- Record parentage, dates and any uncertain hybrid ancestry.
- Identify realistic, responsible homes for juveniles.
