Introduction

Opaline Gouramis, (Trichopodus trichopterus) are an exceptional addition to any aquarium. With their unique colors and attention-seeking nature, they bring character and excitement to a tank. They are also easy to care for, making them an excellent choice for beginner and experienced aquarists alike. Opaline Gouramis are peaceful and interact calmly with other tank mates, except for small fish that they are likely to eat. To avoid aggression between males, it is essential to keep them in groups. These fish enjoy plenty of swimming space, so it 's best to provide a tank of over 90cm in length with a dark-colored substrate and a good amount of aquatic planting to provide shelter. The body of an Opaline Gourami is elongated and flattened laterally, with large transparent pectoral fins and a long anal fin extending from the chest to the base of the tail. The body displays dark patches of different sizes and irregular shapes, which make them stand out in any aquarium. These fish are a color variation of the Blue Gourami and are sure to impress with their unique appearance. T

Breeding

Opaline Gouramis reach sexual maturity between 8-12 months and are known to breed successfully in an aquarium. During spawning, the male constructs a bubble nest at the surface of the water and uses swimming behavior to attract the female. Once the female is ready to spawn, the male will gently embrace her body to aid in the fertilization of the eggs. He then gathers the eggs with his mouth and places them in the nest for fertilization. After laying up to 800 eggs, the female should be removed from the tank to prevent any further stress from the male. The male will protect and tend to the eggs until they hatch, and the fry becomes free-swimming. After this, the male should be removed to avoid any accidental deaths that may occur during the fry 's movements.

Diet & feeding

The Opaline Gourami is an omnivore, and they are not picky eaters. They should be provided with high-quality pellet or flake food as the mainstay of their diet. However, to ensure optimal nutrition and variety, supplementing their diet with live or frozen foods such as brine shrimp, bloodworm, mosquito larvae, or white worms is recommended. Blanched vegetables such as lettuce or peas can also be offered to provide additional nutritional value. They are known to graze on fine-leaved plants, which can be a source of entertainment and nourishment for them. A well-rounded and varied diet is crucial to maintaining the health and vitality of Opaline Gouramis.
