The Opaline Gourami (Trichogaster trichopterus) is a visually striking and hardy species, ideal for both novice and experienced aquarists. A selectively bred variant of the Three Spot Gourami, the Opaline displays an iridescent blue-silver coloration with subtle marbling — adding elegance and tranquility to any freshwater setup.
🌿 Behavior and Temperament
Opaline Gouramis are generally peaceful but may show mild territorial behavior, especially between males. They thrive best in a calm, well-planted aquarium that provides hiding spots such as driftwood, rocks, or dense vegetation. They are surface dwellers and occasionally come up for air, as they possess a labyrinth organ for breathing atmospheric oxygen.
🍽️ Feeding
An omnivorous species, they accept a wide variety of foods — from high-quality flakes and pellets to live or frozen treats like bloodworms and brine shrimp. A balanced diet will maintain their vibrant coloration and boost their natural vitality.
🐟 Tank Requirements
Provide a minimum 30-gallon tank with stable, warm water conditions (75–82°F). Moderate water flow and soft lighting create the most natural environment. Floating plants help reduce stress and mimic their natural habitat.
👨🏫 Care Tips for Beginners
-
Maintain good filtration and regular water changes (20–25% weekly).
-
Avoid housing with aggressive species or fin-nippers.
-
Keep either one male per tank or ensure multiple females to reduce conflict.
-
Observe their behavior during feeding to prevent food competition.
With proper care, Opaline Gouramis can become the highlight of your aquarium, showcasing both beauty and personality.
