The Neon Green Rasbora, scientifically known as Microdevario kubotai, is a vibrant and eye-catching species of small freshwater fish native to Southeast Asia, particularly found in Thailand and Myanmar. This species is highly appreciated in the aquarium trade for its striking neon green coloration and dynamic schooling behavior, making it a favorite among aquarists looking to add a splash of color and activity to their tanks.

Microdevario kubotai is a small fish, typically reaching just over an inch in length, and features a slender, almost translucent body with a bright, iridescent green hue that shines under appropriate aquarium lighting. This makes them not only captivating to watch but also excellent candidates for community tanks with other peaceful, small fish species.

In terms of aquarium care, Neon Green Rasboras thrive in well-planted tanks that offer plenty of cover and free swimming space. They are active swimmers and do best in groups, as their natural schooling instinct is a key aspect of their behavior. Keeping them in groups not only enhances their coloration due to reduced stress but also provides a more natural and visually appealing display.

The water conditions for Neon Green Rasboras should be clean and stable, with a slight acidity and lower hardness, reflecting their tropical freshwater habitat. They are adaptable but sensitive to changes in water quality, so regular maintenance including water changes and effective filtration is essential to keep them healthy.

Their diet should be varied and consist of high-quality small-sized food items to match their diminutive size. A diet of fine flake food, micro pellets, and small live or frozen foods like daphnia or baby brine shrimp will ensure they receive all necessary nutrients. This varied diet not only supports their health but also enhances their vibrant coloration.

Breeding Microdevario kubotai can be achieved with some care. They scatter their eggs among the foliage and do not display parental care, so breeding them in a species-specific tank or a well-planted community tank where eggs can be hidden from adult fish is advisable. Providing a diet rich in live foods and maintaining optimal water conditions can encourage spawning.

While not considered endangered, the Neon Green Rasbora's habitat in Southeast Asia is subject to pressures from deforestation and water pollution. Sustainable practices in the aquarium trade are crucial to ensure that wild populations do not suffer from overharvesting.

Overall, the Neon Green Rasbora is an excellent addition to both novice and experienced aquarist tanks, offering a delightful display of color and natural schooling behavior. Their ease of care, coupled with their stunning appearance, makes them a popular choice for those looking to enhance the biodiversity and beauty of their aquariums.
