General Description: The Neon Blue Danio, commonly still referred to as a Rasbora in the aquarium trade, are endemic to the Greater Sunda Islands of Borneo. Male Neon blue danio are a striking metallic blue-green, with a lighter belly. Females, on the other hand, will be more muted in color (perhaps even completely pale). Depending on locale, there is variation among individuals exhibiting dark or red coloration on the anterior portion of the anal fin. This species is difficult to spawn, thus many of the Neon blue danios available within the aquarium trade are imported from the wild, making them infrequent and somewhat rare. Neon blue rasbora are natural shoaling fish, and males will readily engage in sparring behavior with each other during daylight. Acquiring a group of 15 or more mixed sex individuals is recommended for their social behavior and to spread out aggression among males. An adult Neon blue danio can reach a size of less than 1″.
Diet Requirements: In the wild Neon blue danios are omnivores. A diet made up of various high quality vegetable based and protein based flake foods, sinking micro pellet foods and bug bites are ideal, in addition to offering frozen foods such as bloodworms, brine shrimp and daphnia. Variety is the spice of life in order to maintain color, immune function and longevity of your fish. Avoid foods that will sit on the surface as these fish rarely will come up to eat.
Care Requirements: An established minimum 10 to 15 gallon aquarium is ideal for a group of Neon blue danios. While these fish are small, this size aquarium better provides a stable environment. This species should not be introduced into a biologically immature aquarium. Neon blue danios are very intolerable of nitrite or ammonia spikes, and will not endure deteriorating water parameters. Weekly water changes are encouraged to keep water parameters pristine (Nitrates < 15 ppm). Given the environments in which they come from, Neon blue danios like gentle water flow that is typically achieved by the use of a sponge filter. The aquarium should be aquascaped with a darker substrate and dense vegetation (live plants are preferred). A plant genera this species is commonly associated with in the wild is Elodea. Neon blue danio would also benefit from some floating plants, as this better mimics their natural environment. Neon blue danios are extremely peaceful and rarely conflict with tank mates. Their timid nature, however, may make them not suitable for traditional community aquariums that have overly rambunctious or competitive species that will intimidate them. Mix Neon blue danio with other peaceful shoaling species to provide them with security, and some species that may exploit the top portion of the aquarium to reduce their shyness. Some compatible species include Celestial Pearl Danio (Danio margaritatus), Emerald Dwarf Danio (Danio erythromicron), Exclamation Point Rasbora (Boraras urophthalmoides), Chili Rasbora (Boraras brigittae), and Pygmy Cory (Corydoras pygmaeus). Extra care should be taken acclimating Emerald dwarf danios. This species are great with Neocaridina shrimps. Recommended water conditions, 72-76° F, KH 0-5, pH 4.0-6.5.
