The fireline danio should be maintained in an aquarium of 20 to 29 gallons or larger. Smooth rocks, driftwood (ZM2000) and live or artificial plants may be used, as well as a sand substrate (CS7538). These fish look great in a heavily planted tank with a dark substrate and floating plants to diffuse some of the light..
The fireline danio prefers a temperature of 68°F to 78°F, a pH of 6.5 to 7.5, and a hardness of 1 to 10°H. Be sure water is clean and well oxygenated.
The fireline danio is a generally a peaceful fish suitable for a community aquarium. Good tank mates include most livebearers, other danios, rasboras, tetras and peaceful bottom dwellers such as Corydoras or smaller Loricariids. It can also be kept with most commonly available gouramis and dwarf cichlids. Fireline danios should be kept in schools of at least 8 to 10 individuals to promote schooling behaviors.
The fireline danio is easy to feed in the aquarium and will readily accept just about any appropriately sized food item such as flakes (AL165) and frozen brine shrimp (SF6777). For maximum color, growth, and health these fish will look their best when given probiotics (AL169) in addition to a balanced diet.
