Blue Gouramis, also known as Three-Spot Gouramis or Trichopodus trichopterus, are a popular freshwater fish species. They are native to Southeast Asia, including countries like Thailand, Malaysia, Indonesia, and Vietnam. Here's some information about blue gouramis:

Blue Gouramis have an elongated, laterally compressed body shape. They are known for their beautiful blue coloration, which can range from light blue to a deeper, iridescent shade. They have dark vertical bars on their body and a distinctive dark spot or "eye" on their side, just behind the gill cover. Males often have more vibrant colors and longer fins than females.

Blue Gouramis can grow up to 4 inches (10 cm) in length, with males being slightly larger than females.

Habitat: In the wild, blue gouramis inhabit slow-moving or still waters, such as swamps, ponds, and rice paddies. They prefer warm water temperatures and appreciate soft to moderately hard water conditions.

Blue Gouramis are generally peaceful and make good community fish, although males can become territorial during breeding or in cramped quarters. They have a labyrinth organ, allowing them to breathe atmospheric air, and they will occasionally rise to the water's surface to gulp air. This behavior is normal and helps them supplement oxygen intake.

Blue Gouramis are relatively hardy and suitable for beginner aquarists. They require a well-maintained aquarium with plenty of swimming space and hiding spots. Providing plants, driftwood, and floating vegetation will help create a natural environment and make them feel secure. Regular water changes and maintenance of good water quality are important for their well-being.

Blue Gouramis are omnivorous and accept a variety of foods. They can be fed high-quality flake or pellet food designed for tropical fish. Supplementing their diet with live or frozen foods such as brine shrimp, bloodworms, and daphnia is beneficial. Including some vegetable matter in their diet, such as spirulina-based foods or blanched vegetables, is also recommended.

Blue Gouramis are generally peaceful and can coexist with other peaceful community fish. However, it's important to avoid keeping them with aggressive or fin-nipping species. They are compatible with other peaceful fish like tetras, rasboras, peaceful barbs, and other gourami species.

Breeding blue gouramis in captivity is possible but may require specific conditions. It typically involves providing warm, soft water, floating plants for bubble nest construction, and ensuring the presence of compatible males and females. The male builds a bubble nest at the water's surface, entices the female to spawn, and guards the nest and fry afterward.

Blue Gouramis are admired for their stunning blue coloration and peaceful nature, making them a popular choice for community aquariums. With proper care and suitable tank conditions, they can thrive and provide an attractive addition to your aquatic setup.
