• Scientific name: Microdevario kubotai
• Synonyms: Microrasbora kubotai (Kottelat & Witte, 1999), Green Neon Rasbora, Kubota's microrasbora
• Common name: Neon yellow rasbora
• Group: Cyprinids
• Habitat: Asia; Thailand, Myanmar (Burma)
• Size: 1.5-2 cm
• Biotope: Found in slower-flowing parts of well-oxygenated streams and small rivers. These habitats usually have clear water and sandy substrate, with some larger rocks and boulders, and submerged driftwoods.
• Social behavior: A very peaceful and active schooling fish, that should be kept in a species tank due to its small size, or can be kept in a community tank with similar sized fish that require same water conditions.
• Diet: Omnivorous; in nature they eat small invertebrates and algae. They aren’t choosy eaters in the aquarium, they will accept live, frozen and flake foods too.
• Breeding: Quite easy
• Tank: Minimum 30 litres
• Population: 8-10 fish for 40 litres
• Decoration: They deserve a densely planted tank with some driftwood branches or roots. Use dark substrate with some larger rocks. Stable and good water conditions are very important, and they also require small, regular partial water changes.
• Temperature: 20-27 °C
• pH: 6-7
• Hardness: 1-10 NK°
• Lifespan: 2-3 years

Description: Microdevario kubotai has a yellowish-green body with a metallic gold lateral stripe. All fins are clear. In the nature these fish live in groups of 20-50 individuals, so in the aquarium they should be kept in a larger group, where the males will also display their best colors as they compete with each other.

Mature females are a little larger and plumper than the more intensely-colored males. Like many small cyprinids, Neon yellow rasbora is an egg-scatterer spawner, with no parental care. Well-fed fish will usually spawn, and it is possible that a small numbers of fry will survive in the community tank, but when you would like to maximize their numbers, they should be bred in a separate tank. A small (12-15 litres) tank, that filled aged water and with a few clumps of Java moss is ideal. Lighting and filtration is not necessary, albeit a sponge filter can be useful to maintain water conditions. They can be bred in small groups of a few males and several females, but keep in mind that more fish will raise the possibility of egg predation. After spawning the adults should be removed, as they will eat the eggs and fry. The eggs normally hatch around 72 hours, but this is temperature-dependent, and the fry become free-swimming after another 3-4 days. Initial food should be very small live foods.
