Neon Green Rasbora
Neon Green Rasbora
Neon Green Rasbora (Microdevario kubotai) is a spectacular nano fish with vivid neon-green to yellow-green iridescence covering the entire body — a fish that appears to be lit from within. Named for Kubota, the fish exporter who first brought the species to scientific attention. Despite its name it is not a Sundadanio but a Microdevario — a related but distinct genus of Southeast Asian nano danionids.
Feeding & Care Tip: Hikari Micro Pellets (crushed or soaked briefly) and Sera Vipan Baby make excellent daily staples. Supplement 2–3× per week with Hikari Frozen or Freeze-Dried Baby Brine Shrimp and Hikari Frozen Daphnia. Feed small amounts 2–3 times daily.
Native to rivers and streams of Myanmar and Thailand — not a peat swamp specialist like the Sundadanio species, but sharing the preference for soft, slightly acidic water. The neon-green iridescence is produced by structural color in the scales — particularly vivid under aquarium lighting that matches the reflection wavelength.
Keep in groups of at least 10. The neon-green iridescence is most vivid in moderate to bright aquarium lighting — unlike the Sundadanio species which prefer dim conditions, the Neon Green Rasbora shows better color in brighter planted tank lighting. Compatible with other small, peaceful community species.
One of the most purely and brilliantly green nano fish available — a large school of Neon Green Rasboras in a well-lit planted aquarium is a spectacular and unusual sight.
