Opaline Gourami

Opaline Gourami (Trichogaster trichopterus Variation)

The Opaline Gourami, also known as Marbled Gourami and Cosbys Gourami, is a captive-bred variation of the Three Spot Gourami. This variant is characterized by its unique opalescent coloration, which distinguishes it from its Three Spot Gourami relative.

They are beautiful, hardy, and adaptable fish that makes a great addition to many community aquariums. This stunning fish is a sight to behold, with a shimmering blue and silver coloration that gives it an opalescent appearance.

They grow to be around 4-6 inches in size and have a peaceful temperament, making them suitable for a variety of tankmates.

Opaline Gouramis are captivating fish that display a range of intriguing behaviors. They can be observed navigating various levels of the tank, often rising to the surface to gulp air. Each Opaline Gourami possesses a distinct personality, with some exhibiting shyness while others are more lively and energetic.

Each Opaline Gourami has its own unique level of tolerance when it comes to coexisting with other tankmates. Opaline Gouramis are usually peaceful when young but may develop semi-aggressive behaviors as they age. Being skilled predators, they may target smaller fish in the tank. Additionally, these Gouramis use their sensitive pelvic fins to explore their surroundings and could become aggressive towards fin-nipping fish. Monitoring your aquarium closely and making necessary adjustments if you notice any signs of bullying is essential.

Opaline Gouramis are omnivorous, enjoying a diet of both plant-based and meaty foods. They will readily accept high-quality flakes, pellets, and freeze-dried or frozen foods such as bloodworms, brine shrimp, and daphnia.

These fish prefer dimly lit, slow-moving water and a densely planted aquarium with plenty of hiding spaces, as they can be shy and sometimes territorial, especially during breeding.

A tank with a minimum size of 30 gallons is recommended, and they will thrive in water conditions with a pH of 6.0-8.0, hardness of 5-20 dGH, and a temperature range of 72-82°F (22-28°C).
