Let’s break this process down into several key components:

  • Tank size: Dwarf gouramis, as their name suggests, are relatively small fish, but don’t let this fool you into getting a tiny tank. For a single dwarf gourami, a tank of at least 10 gallons is ideal; if you have more fish, increase the tank size accordingly. Remember, bigger is generally better for ensuring a stable aquatic environment.
  • Aquarium substrate: A fine and soft substrate, like sand or small gravel, is the best choice for your dwarf gourami tank. Avoid sharp-edged substrates that could potentially injure your fish. Dwarf gouramis appreciate a well-planted tank, so ensure you either add live plants or natural-looking artificial ones that provide ample hiding spots.
  • Tank decorations: In addition to plants, consider adding decorations such as rocks and driftwood that can serve as hiding places and additional visual interest for your gouramis. Just make sure they are safe and don’t have sharp edges that could harm your fish.
  • Filtration: Dwarf gouramis appreciate calm waters, so opt for a filter with adjustable flow control. Ensure the filter has biological, mechanical, and chemical filtration capabilities to maintain pristine water conditions.
  • Heater and thermometer: Dwarf gouramis are tropical fish and require a consistent water temperature between 72 – 82°F. Therefore, investing in a reliable heater and thermometer is vital for maintaining a stable environment.
  • Lighting: Moderate lighting is ideal for dwarf gouramis. In addition, many aquarium plants require light to grow, so a combination of LED lights with a timer can be a great solution to cater to both the fish and plant needs.

Dwarf Gourami Water Requirements

Dwarf Gouramis are native to slow-moving, vegetated waters in Asia, making them adaptable to a range of water parameters. However, to ensure your fish remain healthy and happy, it’s important to provide a stable environment that closely mimics their natural habitat.

To achieve this, maintain a consistent water temperature of 72-82°F (22-28°C). Use an aquarium heater to maintain the temperature and an aquarium thermometer to monitor it. Dwarf Gouramis do best in a slightly acidic to neutral environment, so aim for a pH level between 6.0 and 7.5.

  • Regularly test the pH level in the tank using a reliable test kit and adjust the pH as necessary.
  • Aerate the water moderately to provide dissolved oxygen, as these fish prefer water with a lower flow.
  • Make sure the water hardness stays between 5-18 dGH.

An essential factor for keeping your fish healthy is to manage the nitrogen cycle. Dwarf Gouramis are sensitive to ammonia, nitrite, and nitrate levels, so regular water testing and changes are important.

  • Perform water tests at least once a week, especially in a new tank.
  • Invest in a high-quality water test kit to monitor the ammonia, nitrite, and nitrate levels.
  • Conduct regular water changes of 25-50% weekly to keep the water quality stable.

Proper maintenance will help in providing optimal water conditions for your Dwarf Gouramis. Remember that drastic fluctuations in temperature, pH, or water hardness can stress your fish, making them more susceptible to diseases. By following these guidelines, you can ensure that your Dwarf Gouramis thrive in their aquatic environment.

Dwarf Gourami Diet and Feeding

Dwarf Gouramis are omnivores, meaning their diet consists of both plant-based and animal-based foods. To keep them healthy and colorful, it’s important to provide them with a balanced diet comprising a variety of high-quality food.

  • Commercial fish food: You can provide them with high-quality flakes or slow-sinking pellets designed for tropical fish. Feed them this at least once a day.
  • Frozen and live foods: For optimal health, supplement their diet with frozen or live foods such as daphnia, brine shrimp, and bloodworms. Doing this a couple of times a week will do wonders for their well-being and colors.
  • Vegetables: Vegetables like spinach and lettuce are beneficial for their health too. To feed them vegetables, simply blanch them in boiling water, let them cool, and then chop them into small pieces before adding to the tank.

Feeding your Dwarf Gouramis is pretty simple. You just need to observe the following guidelines:

  1. Feed small portions: Put in only an amount that they can consume within 3-5 minutes to avoid overeating and producing leftover food.
  2. Feed them 2-3 times a day: Providing them with small portions multiple times throughout the day imitates their natural feeding pattern in the wild.
  3. Clean up leftover food: Remove any food left behind after feeding time to maintain water quality and prevent ammonia build-up.

By providing your Dwarf Gouramis with a balanced diet, you ensure their health, vibrant colors, and active behavior. Proper feeding also helps you maintain a clean and healthy aquarium environment.

Breeding Tank Requirements: Prepare a separate tank with a minimum size of 5-10 gallons, and maintain a water temperature between 78-82°F (25-28°C). Keep the water level between 6-8 inches, and provide floating plants to replicate their natural habitat for bubble nest building.

To initiate the spawning process and care for eggs and fry, follow these 6 steps:

  1. Separate the Male and Female: Place the male and female in separate tanks or use a divider to avoid premature interactions.
  2. Condition the Fish: Feed them with high-quality, protein-rich live or frozen foods, like brine shrimp, bloodworms, and daphnia, to improve their overall health and encourage breeding behavior.
  3. Introduce the Pair: Place the female in a breeding container or release her into the male’s tank when you notice the female’s belly swelling with eggs, and the male starts the bubble nest building.
  4. Monitor the Spawning: Observe the pair as the male wraps himself around the female, releasing milt to fertilize the eggs. They will repeat this process multiple times.
  5. Remove the Female: After spawning, take the female out of the breeding tank to avoid being harassed by the male, who will continue to care for the eggs.
  6. Care for the Fry: Once the fry hatches, usually within 24-36 hours, remove the male from the breeding tank. Ensure the fry are fed with nutrition-rich foods such as infusoria and baby brine shrimp, and perform regular water changes.

Important Note: You should only attempt breeding when you are well-prepared and committed to the care of the fish and their offspring, as it is a responsible and resource-intensive process.


Caring for dwarf gouramis can be a rewarding experience for beginners and experienced aquarists alike.
