\nThe Ruby Tetra (*Axelrodia riesei*) is a stunningly small fish, growing to approximately 2.5-3 cm, known for its intense ruby-red coloration that often deepens with age and optimal care. Native to the blackwater tributaries of Colombia, they exhibit a fascinating shoaling behavior, preferring to swim in loose groups rather than tight schools. Their active yet gentle nature makes them a serene addition, frequently exploring the mid to upper water column of your aquarium.<\/p>\n
\nThe Ruby Tetra is considered a moderately easy fish to care for, thriving best in a stable, well-established environment. They are peaceful community fish, ideal for planted tanks and nano aquariums. Always keep them in groups of at least 8-10 individuals to encourage natural behavior and reduce shyness. Choose tankmates carefully, opting for other small, peaceful species that won’t outcompete them for food.<\/p>\n
\nA minimum tank size of 38 litres (10 gallons) is recommended for a healthy group of Ruby Tetras. They flourish in soft, acidic water with a pH range of 4.0-6.5 and temperatures between 20-28\u00b0C. Replicate their natural blackwater habitat with dim lighting, dark substrate, and plenty of plant cover and driftwood.<\/p>\n
\nRuby Tetras are micropredators, readily accepting a varied diet of high-quality, small-sized foods. Offer finely crushed flakes, micro pellets, and a mix of live or frozen options such as brine shrimp, daphnia, and microworms to enhance their vibrant coloration.<\/p>\n
