Neon Green Rasbora (Microdevario kubotai)

Neon Green Rasboras have a peaceful disposition and are relatively hardy, making them wonderful members of the well-planted or nano aquarium. A large school of Neon Green Rasboras will fill the upper area of the aquarium with so much colour and activity that even non-hobbyists will appreciate the display.

It would be best to keep Neon Green Rasboras in groups of 8 to 10 individuals as they are a schooling species in the wild. Maintaining them in more significant numbers will make these fish less nervous and result in a natural, more effective looking display. In addition, males will also display their best colours as they compete with each other for female attention.

It would be best if you housed these Rasboras in either a species-only setup or alongside other small, peaceful fish such as small Tetras, Danios, small Rasbora species and Corydoras Catfish.

Neon Green Rasboras are not always suitable for the typical community aquarium because of their small size and slightly timid nature. However, if you have larger groups, plenty of coverage and peaceful tankmates, it could work and give them much more confidence.

The aquarium should be designed so that there are areas of dense planting, including shady bogwood pieces. These Rasboras would also appreciate the addition of some floating plants to help diffuse the light. The aquarium needs to have moderate water movement to encourage good oxygenation levels; however, the current should not be too harsh. The aquarium must be well established, and you will need to perform plenty of small partial water changes regularly.

Neon Green Rasboras have greyish-olive bodies with an iridescent greenish-yellow hue. In addition, they possess a prominent metallic yellowish-gold lateral stripe, and their dorsal and anal fins are translucent.

In the home aquarium, the Neon Green Rasbora will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is somewhat straightforward to differentiate between male and female Neon Green Rasboras. Mature males will be more vibrantly coloured and more compact than females. In contrast, the females will typically be slightly larger and will take on a more gravid appearance when ready to reproduce.
