General Description: The Emerald Dwarf Danio, commonly still referred to as a Rasbora in the aquarium trade, is native to an isolated mountain lake and surrounding watershed in Myanmar. Male Emerald dwarf danios will have well-defined iridescent vertical blue bars along its body and red coloration in some of its fins. Females, on the other hand, will be more muted in color (perhaps even tan-beige) and have less definition in their markings. Easy to spawn, many of the Emerald dwarf danios available within the aquarium trade are commercially produced. Emerald dwarf danios are natural shoaling fish, and males will readily engage in sparring behavior with each other during daylight. Acquiring a group of 15 or more individuals is recommended for their social behavior and to spread out aggression among males. It is not recommended to mix Emerald dwarf danios with Celestial pearl danios (Danio margaritatus), as these species can hybridize. An adult Emerald dwarf danio can reach a size of approximately 1″.
Diet Requirements: In the wild Emerald dwarf 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: A minimum 10 to 15 gallon aquarium is ideal for a group of Emerald dwarf 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. Emerald dwarf 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, Emerald dwarf 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. Emerald dwarf danio would also benefit from some floating plants, as this better mimics their natural environment. Emerald dwarf 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 Emerald dwarf 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), Neon Blue Danio (Sundadanio axelrodi), Exclamation Point Rasbora (Boraras urophthalmoides), Chili Rasbora (Boraras brigittae), and Pygmy Cory (Corydoras pygmaeus). This species are great with Neocaridina shrimps. Extra care should be taken acclimating Emerald dwarf danios. This danio will not do well in acidic water. Recommended water conditions, 72-76° F, KH 6-12, pH 7.0-8.0.
