Brilliant Rasbora

Brilliant Rasbora (Rasbora Einthovenii)

The Brilliant Rasbora, also known as Einthoven's Rasbora, is a striking freshwater fish known for its vibrant colors and shimmering scales. With a slender, torpedo-shaped body, the Brilliant Rasbora displays a bright, metallic silver base color with a hint of iridescence.

Brilliant Rasbora can reach an adult size of around 2 inches and is best kept in schools of at least 6 individuals to encourage their natural social behavior. These peaceful fish are well-suited for community tanks with similarly sized, non-aggressive tank mates. Tank companions could include other rasboras, tetras, and small peaceful catfish. The Brilliant Rasbora's temperament makes it an excellent addition to most peaceful aquarium setups.

As omnivores, Brilliant Rasboras require a varied diet consisting of high-quality flake or pellet food supplemented with live or frozen foods, such as brine shrimp, daphnia, and bloodworms. They will also appreciate the occasional inclusion of vegetable matter in their diet.

For an ideal tank habitat, provide a well-planted aquarium with a soft, sandy substrate and additional hiding spots in the form of driftwood and rocks. They prefer dimly lit conditions, which can be achieved with floating plants or subdued lighting. Plants native to Asia, such as Microsorum pteropus, Vesicularia dubyana, or potted Cryptocorynes, can thrive in low-light conditions and are suitable for the Brilliant Rasbora's habitat. Floating plants can also help to diffuse incoming light further. It is important to avoid introducing this fish to a biologically unstable aquarium, as it is sensitive to fluctuations in water chemistry.

A minimum tank size of 10 gallons is recommended, with larger tanks being preferred for bigger schools. The ideal water parameters for these fish include a pH of 6.0-7.5, a hardness of 5-12 dGH, and a temperature range of 72-79°F (22-26°C).

Additionally, a securely fitted lid is essential to prevent escape, as the Brilliant Rasbora, like most rasboras, is an adept jumper.
