Neon Green Dwarf Kubotai Rasbora (Microdevario kubotai)

The Neon Green Dwarf Kubotai Rasbora (Microdevario kubotai) is a small, vibrant freshwater fish native to peninsular Thailand and nearby regions. It inhabits slow-moving, shaded streams with abundant vegetation, leaf litter, and fine gravel or sand substrates. Its compact size, typically around 2–3 centimeters, and striking neon-green to yellow-green coloration with a dark lateral stripe make it highly appealing to aquarists seeking a lively, visually striking species for planted aquariums. The combination of bright coloration and active movement adds natural energy to any tank, creating a shimmering mid-water presence that contrasts beautifully with plants and darker substrates.

In the aquarium, Kubotai Rasboras are peaceful schooling fish that thrive in groups of six or more, which encourages natural shoaling behavior and enhances their dynamic display. They prefer moderately soft to slightly hard water with a pH around 6.0–7.5 and temperatures between 22–26°C. Gentle water flow, dense plantings, and ample swimming space allow these fish to show their best colors and behavior. They move gracefully through plants and open areas alike, making them ideal for planted nano tanks, community setups, or aquascapes where small, active mid-water fish are desired. Their natural social tendencies make them fascinating to observe as they dart, glide, and interact within the group.

For aquarists seeking a compact, colorful, and lively species, the Kubotai Rasbora is an excellent choice. Its neon green shimmer provides striking contrast within planted aquariums, while its peaceful nature ensures compatibility with other small, non-aggressive fish. The species flourishes when water quality is stable, with ample cover and open swimming zones that allow their schooling behavior to shine. When properly maintained, they bring constant motion, visual interest, and natural beauty to planted tanks and aquascapes, making them a rewarding addition for both beginner and experienced hobbyists alike.
