Micro Rasboras

Galaxy Rasbora is another name for the spotted Celestial Pearl Danio, Danio margaritatus. Emerald Dwarf Rasbora is the barred Danio erythromicron. Neon Green Rasbora is Microdevario kubotai, formerly called Microrasbora kubotai. The Microrasbora name here keeps these familiar shopping names together; it does not make them one species. The hybrid listing names both parents and should not be bought as a pure Galaxy or Emerald.

Neon Green and Emerald Dwarf are not interchangeable choices for the same water. Their species guidance differs substantially: Neon Green uses 1–10 dGH, while Emerald uses 12–20 dGH. Measure your aquarium's hardness, pH and temperature, then compare the full requirements of your chosen fish and existing residents. The hybrid's water requirements are unconfirmed; ask about that exact offer before planning its tank.

A tiny adult fish still needs company and swimming room. For Neon Greens, plan a mature aquarium with at least a 60 × 30 cm base; our listing uses ten fish as its cautious starting group. Provide fine foods they can swallow and calm companions that will not take every meal first. Follow the separate group and space advice for Galaxy and Emerald fish. Quantity discounts and the number of fish pictured are not stocking recommendations.
