Kubotai Rasbora (Microdevario kubotai), Tank-Bred

Species Overview

The Kubotai Rasbora, often referred to as the Neon Green Rasbora or Green Kubotai Rasbora, is one of the brightest nano fish available for freshwater planted aquariums. Its brilliant neon green body seems to glow under aquarium lighting, creating an eye-catching display that contrasts beautifully against lush aquatic plants and darker aquascapes. Despite their small size, a healthy school of Kubotai Rasboras can become the visual centerpiece of an aquarium through their synchronized swimming and vibrant coloration.

The Kubotai Rasboras offered by Aquatic Arts are tank bred, providing hobbyists with healthy, aquarium-acclimated fish that readily adapt to life in planted community aquariums. Their peaceful temperament and active schooling behavior make them excellent choices for nano aquariums, nature-inspired aquascapes, and larger freshwater community tanks where they add constant movement without disturbing other inhabitants.

Kubotai Rasboras are true schooling fish that display their best coloration, confidence, and natural behavior when maintained in groups. As they move together through open swimming areas, the school creates flashes of neon green that weave between plants and hardscape, bringing life and energy to every level of the aquarium.

Whether you're building a high-tech aquascape, a peaceful nano community, or a thriving freshwater ecosystem filled with plants, shrimp, and other small community fish, the Kubotai Rasbora is an outstanding choice. Their brilliant coloration, gentle disposition, and active personality have made them one of our favorite nano schooling fish for planted aquariums.
