Green Neon Rasbora

Microdevario kubotai (formerly Microrasbora kubotai), also known as Green Neon Rasbora, is native to Southeast Asia. Its distribution area extends from Myanmar, across the Malay Peninsula to Thailand. Rivers and streams with low to medium currents and underwater vegetation represent its natural habitat. The Green Neon Rasbora has a partially emerald green, iridescent body color, which also gives it its name. With a maximum body length of 2 cm, it is one of the smallest rasboras.

Care in the aquarium

The Green Neon Rasbora can be kept in an aquarium with a capacity of 54 liters or an edge length of 60 cm. Dense edge planting, roots or stone structures serve as hiding places and places to retreat and ensure that the fish feels comfortable and behaves less shyly. As a schooling fish, it should also be kept together with at least 10 members of its species. For this fish, which loves swimming, there should still be enough free swimming space and the water current should be moderate. The aquarium water should be soft to medium hard and have a temperature between 22 and 26°C. As a somewhat shy fish, the Green Neon Rasbora is only partially suitable for community aquariums and should only be kept with other small, peaceful and calm animals. Keeping peaceful invertebrates such as dwarf shrimps is possible without any problems.

Feeding

Microdevario kubotai can be fed flake and small granular food as well as small live and frozen food. Daphnia, artemia nauplii, copepods and cyclops, for example, are very suitable.

Sexual characteristics and breeding

Male Green Neon Rasboras have a slightly more pointed tail fin, while females have a rounded caudal fin. When fully grown, the males are also a little bit smaller and slimmer than their female counterparts. In order to increase their willingness to spawn, the Green Neon Rasboras can be pampered with more live food. This fish is a free-spawning fish; the eggs are laid by the female between fine-feathered plants or mosses and fertilized there by the male. The young fish hatch after about 1-2 days and can be fed with very fine live food or dust food another 2-3 days later, after the yolk sac has been consumed.
