Aggression and Territoriality

While gouramis are generally peaceful, some species can display territorial behavior, particularly during breeding. Providing ample hiding spots and visual barriers, such as plants or driftwood, helps reduce aggression and provides a sense of security for the fish.

Breeding Gouramis


Breeding Behavior

Gouramis are known for their unique breeding behavior. Males build bubble nests at the water’s surface using saliva and plant matter. The female lays eggs after a successful courtship, and the male fertilizes them. The male gourami guards the nest and cares for the eggs and fry.

Gouramis Breeding Setup

To encourage breeding, maintain optimal water conditions, and provide suitable plants or spawning mops for the female to deposit her eggs. The male will diligently tend to the eggs and fry, ensuring their safety and well-being. Separating the breeding pair from other tankmates during the breeding process can also prevent disturbances.

Here’s a step-by-step guide on how to set up a Gourami breeding tank:

1. Select the Right Gourami Species:

  • Ensure you have a male and female pair of Gouramis. Some species, like Dwarf Gouramis, are easier to breed in captivity.

2. Separate Breeding Tank:

  • Set up a separate breeding tank. A 10 to 20-gallon tank is usually sufficient for most Gourami species.

3. Water Parameters:

  • Maintain stable water conditions:
    • Temperature: 78-82°F (25-28°C).
    • pH: Slightly acidic to neutral (6.5-7.0).
    • Ammonia and nitrite levels should be at zero, and nitrates should be low.

4. Decor and Substrate:

  • Use fine-leaved plants such as Java moss or artificial spawning mops to provide hiding places for the fry.
  • Include floating plants to diffuse light and provide cover for the bubble nest.

5. Filtration:

  • Use a sponge filter or a gentle air-driven filter to avoid strong currents that could disrupt the bubble nest.

6. Conditioning the Breeders:

  • Feed the breeding pair high-quality foods, including live or frozen foods, to condition them for breeding.

7. Introduce the Pair:

  • Place the male and female Gouramis in the breeding tank together.

8. Bubble Nest:

  • Male Gouramis are bubble nest builders. They will create a nest on the water’s surface using bubbles. Provide floating plants to assist in nest-building.

9. Spawning Behavior:

  • Observe the courtship and spawning behavior. The male will entice the female under the bubble nest.

10. Egg Laying: – The female will release eggs, and the male will fertilize them. The male will collect the eggs and place them in the bubble nest.

11. Remove the Female: – After spawning, it’s essential to remove the female from the breeding tank to prevent her from eating the eggs or attacking the male.

12. Care for the Fry: – The male will protect the nest and the hatching fry. Once the fry is free-swimming, usually within a few days, you can start feeding them with specialized fry food or powdered flakes.

13. Maintain Water Quality: – Ensure excellent water quality in the breeding tank. Perform regular water changes to keep the environment clean.

14. Monitor Growth: – As the fry grows, you may need to separate them into a larger tank or provide additional hiding spots.

15. Offer Varied Diet: – As the fry grows, introduce a variety of small foods, including baby brine shrimp, micro worms, or finely crushed flakes.

16. Patience: – Breeding Gouramis can take time and patience. Not every attempt may be successful, so be prepared for multiple breeding attempts.

17. Record Keeping: – Keep records of breeding dates, water parameters, and any observations. This information can be valuable for future breeding attempts.

Rearing Fry

Once the eggs hatch, the male gourami continues to care for the fry. After a few days, the fry will become free-swimming and can be fed infusoria or commercially available liquid fry food. As they grow, gradually introduce finely crushed flakes or powdered fry food to their diet.
