电光美人
The Dwarf Neon Rainbowfish was scientifically described by Weber & Beaufort in 1910. Its scientific name is Melanotaenia praecox.
The Dwarf Neon Rainbowfish can reach a length of roughly 6 cm. The body is neon blue with contrasting red dorsal, anal and caudal fins.
The Dwarf Neon Rainbowfish is of a peaceful disposition and can be kept with other non-aggressive species in the community aquarium or with its own kind only in a species aquarium. Always keep at least five Dwarf Neon Rainbowfishes together, ideally more. Ideally combine fishes of roughly the same size. The aquarium should contain a lot of aquatic plants and good hiding spots. Keep the water temperature in the 22-28 degrees range. Unlike many other rainbowfishes, the Dwarf Neon Rainbowfish prefers acidic water.
