General Description
Dario Hysginon, commonly known as "red melon Dario" or "flame red Dario," is a species within the Badidae family. These fish exhibit beautiful coloration, with males displaying extended pelvic, dorsal, and anal fins. Females, smaller in size, have a stumpier body profile compared to males. They are micropredators, feeding on small aquatic crustaceans, worms, insect larvae, and zooplankton.
Aquarium Setup
Maintaining Dario Hysginon in a well-structured tank with plenty of cover is ideal. A soft substrate or fine-grade gravel is suitable, along with plants like Cryptocoryne spp., Microsorum, Anubias, or Taxiphyllum species. Driftwood, floating plants, and leaf litter are beneficial additions. The optimal water conditions are a hardness of 18-90ppm, pH range of 6.5-7.5, and a temperature between 15-25°C.
Behaviour
Being non-gregarious, Dario Hysginon can be aggressive towards rival males, especially in smaller tanks. In more extensive setups, a group can coexist if territories are well-defined and there is ample space. Thoughtful placement of caves and boundaries helps reduce aggression. These fish are slow-moving and timid, easily intimidated by larger or boisterous tankmates. Selecting peaceful, pelagic cyprinids or diminutive loaches as tankmates is recommended.
Feeding and Diet
Dario Hysginon are deliberate feeders, preferring small live or frozen foods like Artemia nauplii, Daphnia, grindal, and micro-worms. They should not be fed chironomid larvae or Tubifex to avoid obesity and susceptibility to diseases.
Reproduction & Dimorphism
This species is a substrate spawner, forming temporary pair bonds during breeding. Males exhibit territorial behavior and intensified coloration when ready to spawn. Females lay eggs on solid surfaces, and males guard the territory post-spawning. Sexual dimorphism is pronounced, with males being more colorful and having extended fins compared to smaller, stumpier females.
Habitat and Distribution
Dario Hysginon is endemic to Myanmar, specifically found in small streams and tributaries near Myitkyina in Kachin State, and Lake Indawgyi within the Irrawaddy/Ayeyarwady river system. They prefer still pools with abundant aquatic vegetation. The species coexists with various fish species like Badis corycaeus, inhabiting different ecological niches within their habitat. Kachin State, where they originate, is known for its biodiversity and endemic species, although facing threats from illegal logging.
