Dwarf Gourami | Single

The Dwarf Gourami (Trichopodus lalius), also known as the Red Colisa Gourami or Scarlet Gourami, is a small, vibrant freshwater fish that is popular in home aquariums due to its peaceful nature and striking colors. Native to South Asia, this species is known for its beauty, easy care requirements, and adaptability to various tank conditions.
Key Characteristics of Dwarf Gourami:
Size: Typically grows to about 2–3 inches (5–7.5 cm) in length.
Color: Males are particularly colorful, with bright red, orange, or blue hues depending on the variety. Females are generally paler with more subdued colors (yellow or pale orange). The fish also has an iridescent sheen, making them quite attractive in the aquarium.
Lifespan: 3–4 years with proper care.
Behavior: Peaceful, calm, and social. Dwarf Gouramis are generally non-aggressive but may exhibit some territorial behavior during breeding, especially males.
Activity Level: Moderate; they tend to swim in the mid to top levels of the tank and prefer calm waters.
Water Parameters for Dwarf Gourami:
Temperature: 24–28°C (75–82°F).
pH: 6.0–7.5, slightly acidic to neutral water.
Hardness: 5–15 dGH.
Tank Size: A minimum of 10 gallons for a single fish or a small group. For a group of 2–3 fish, a 20-gallon tank or larger is recommended.
Tank Setup for Dwarf Gourami:
Substrate: Fine gravel or sand is ideal. Darker substrates can enhance the fish’s natural colors.
Plants: Live plants are essential as they provide hiding spots and grazing areas. Plants like Java fern, Anubias, and Amazon sword are excellent choices.
Lighting: Moderate lighting that highlights the fish’s coloration. Too much light may cause stress, so provide shaded areas with floating plants.
Water Flow: Low to moderate water flow. Dwarf Gouramis are not strong swimmers and prefer calm water, so avoid powerful filters or water pumps.
Decor: Provide hiding spots with rocks, driftwood, or additional plants to reduce stress and create a natural environment.
Diet:
Dwarf Gouramis are omnivores and should be fed a varied diet:
Staple Foods: High-quality tropical fish flakes or pellets.
Protein Sources: Live or frozen foods such as brine shrimp, daphnia, and bloodworms.
Vegetable Matter: Blanched spinach, zucchini, or spirulina-based foods.
Feeding Tip: Feed small portions 2–3 times a day. They are slow eaters, so make sure to remove any uneaten food to avoid water contamination.
Behavior and Tankmates:
Behavior: Dwarf Gouramis are peaceful, but males can become territorial during breeding periods. They may also display mild aggression toward other males, especially if they feel threatened or confined in a small space.
Tankmates:
Compatible Species: Peaceful species like small tetras, rasboras, Corydoras catfish, and other non-aggressive fish. They also get along with other Gouramis and peaceful barbs.
Avoid: Aggressive or fin-nipping species such as bettas, large cichlids, or tiger barbs that may stress the Gouramis or damage their fins.
Breeding Dwarf Gourami:
Breeding Dwarf Gouramis in captivity can be quite simple, but the process requires some preparation:
Breeding Tank: Set up a breeding tank with warm water (28–30°C) and plants or floating spawning mops where the female can lay eggs.
Conditioning: Feed the breeding pair live or frozen foods to encourage spawning.
Spawning Behavior: The male will build a bubble nest at the water's surface. During courtship, he will display his colorful body to attract the female. Once the female is ready, she releases eggs into the bubble nest, where the male fertilizes them.
Egg Care: After spawning, the female should be removed to avoid aggression from the male. The male will guard the nest until the eggs hatch, which usually occurs in 24–48 hours.
Fry Care: The fry will initially need infusoria or liquid fry food until they are large enough to consume finely crushed flakes or baby brine shrimp.
Care Tips:
Group Size: Dwarf Gouramis can live alone, but they are more comfortable in small groups of 2–3 fish. If you have multiple males, it’s best to provide plenty of hiding spots to reduce aggression.
Water Quality: Maintain regular water changes (about 20–30% each week) to ensure good water quality. Poor water conditions can lead to stress or illness.
Tankmates: Choose peaceful fish to avoid aggression or fin-nipping, which can stress the Gourami.
Environment: Dwarf Gouramis appreciate a well-planted tank with floating plants to mimic their natural habitat. This provides a safe space for them to hide and feel secure.
