Neon Green Rasbora (Microdevario kubotai)

Microdevario kubotai runs an iridescent green-yellow stripe down a body barely three-quarters of an inch long, the same structural light-scattering trick behind neon tetra blue just shifted into a different part of the spectrum. It's genuinely one of the smaller schooling fish in the trade, built specifically for a nano tank rather than a general community setup. A tight group under decent lighting turns that green stripe into a moving accent line through the whole school.

Care level: Easy · Temperament: Peaceful, shoaling · Max size: ~0.75" · Min tank: 10 gal · Diet: Omnivore, micro-pellet/flake
