Green Neon Rasbora (Microdevario kubotai)
The Green Neon Rasbora is a dazzling nano fish celebrated for its brilliant fluorescent green coloration and active schooling behavior. Also known as Kubotai Rasbora, this tiny freshwater fish glows under aquarium lighting, creating a spectacular display as schools weave through lush aquatic plants. Its peaceful temperament, vibrant color, and small size make it one of the most popular choices for planted aquariums and nano community tanks.
Native to the slow-moving streams and wetlands of Thailand and Myanmar, Green Neon Rasboras inhabit heavily vegetated waters with gentle flow and abundant plant cover. In the aquarium, they thrive in well-planted environments with driftwood, dark substrate, and open swimming space. They are highly social fish and should always be kept in groups of at least 8–10 individuals. Larger schools encourage natural behavior, reduce stress, and create an even more impressive display of shimmering green color.
Green Neon Rasboras are easy to care for in mature aquariums with stable water parameters. They readily accept finely crushed flakes, nano pellets, frozen baby brine shrimp, daphnia, cyclops, and other small live or frozen foods. Providing a varied diet helps maintain their vivid coloration and supports overall health.
Their gentle disposition makes them ideal companions for other nano fish, shrimp, Corydoras, otocinclus, and peaceful community species. They are particularly striking when kept in densely planted aquascapes, where their bright green coloration contrasts beautifully with dark wood and lush aquatic plants.
