Brilliant Rasbora (Rasbora einthovenii)
Originating from Southeast Asia, particularly Malaysia, Sumatra, and Borneo, the Brilliant Rasbora thrives in slow-moving streams and heavily planted areas. In aquariums, these fish display stunning metallic coloration and shimmering reflections under good lighting. Their graceful schooling behavior and peaceful temperament make them ideal for planted and community aquariums alike.
Brilliant Rasbora size averages 2.5–3 inches (6–7.5 cm) when fully grown. Their slim, torpedo-shaped bodies are marked by a striking black line that runs from the gill plate to the caudal fin, bordered by shimmering silver and gold hues.

I’ve had my Brilliant Rasbora for three months now. They’re very active and form a beautiful school. The silver and gold colors shine under my LED lights, especially in the evening. They don’t stress other fish and are easy to maintain in a planted tank.

The fish arrived healthy and seem to be adjusting well. Their black and silver pattern is striking. I keep them in a 10-gallon tank with java fern and driftwood. They swim calmly and don’t chase other species.
