Opaline Gourami Care Guide
Trichopodus trichopterus var. Opaline · Freshwater Fish
What Opaline Gourami look like
The Opaline Gourami (Trichopodus trichopterus var. Opaline) exhibits a laterally compressed, fusiform body shape, characterized by its vibrant iridescent blue and green coloration, which is particularly pronounced in males during breeding. Adults can reach a maximum size of approximately 5 to 6 inches (12 to 15 cm). Sexual dimorphism is evident, with males displaying more intense coloration and elongated dorsal and anal fins compared to the more rounded fins of females. Defensive adaptations include the ability to produce a mucous layer that can deter predators. Unique morphological features include a prominent dorsal fin that extends along the back, an adipose fin, and a well-developed lateral line system that aids in navigation and social interactions within their environment.
Behavior & temperament
Opaline Gouramis are generally peaceful and can exhibit a semi-social behavior, often found in small groups or pairs, although they can also be solitary. They primarily inhabit the middle to upper water column, preferring densely planted areas where they can seek refuge. Their breeding behavior is characterized as an egg scatterer, where males build bubble nests to attract females. During breeding, males display courtship behaviors, including fin flaring and chasing. While they are not aggressive, males can display territoriality, especially during the breeding season, and may show mild aggression towards other males.
Diet & feeding
In the wild, Opaline Gouramis are omnivorous, feeding on a varied diet that includes small invertebrates, plant matter, and detritus. In captivity, they thrive on a balanced diet that includes high-quality flake food, frozen or live foods such as brine shrimp and daphnia, as well as vegetable matter like spirulina and blanched greens.
