Dario Sp. 'Myanmar'

Datasheet

Behaviour

The Black Tiger Dario is not a gregarious fish and can exhibit aggressive behavior towards rival males, especially in smaller tanks. To prevent aggression, it is recommended to maintain them alone or in a single pair. In more spacious environments, a group can coexist if each male has enough space to establish a territory. Thoughtful placement of caves and boundaries can aid in reducing aggression. When housed in a community tank, peaceful and smaller fish species like Microdevario, Boraras, or Trigonostigma are suitable tankmates, as larger or more boisterous companions may intimidate or outcompete the Black Tiger Dario.

Feeding and Diet

Black Tiger Dario are micropredators that feed on small aquatic crustaceans, worms, insect larvae, and zooplankton. In captivity, they should be offered small live or frozen foods like Artemia nauplii, Daphnia, and various types of worms. Avoid feeding them chironomid larvae (bloodworm) and Tubifex as these can lead to obesity and increased susceptibility to diseases. They are shy feeders and should be provided with appropriate food to maintain their health.

Reproduction & Dimorphism

Black Tiger Dario are substrate-spawners that form temporary pair bonds during breeding. Males exhibit brighter colors and develop extended fins compared to females. During courtship, males display intensified colors and behavior, inviting the female to spawn in his territory. After spawning, the male guards the eggs while the female is chased away. To increase fry survival, adults or spawning medium should be removed post-spawning. The female scatters eggs on surfaces, and the male cares for the territory and fry.

Habitat and Distribution

Black Tiger Dario is endemic to northern Myanmar, specifically near the city of Myitkyina. They prefer small, sometimes turbid pools with dense aquatic plant growth. Their natural habitat is similar to D. hysginon, which favors small pools with aquatic plants or submerged grasses, providing them with shelter and breeding spaces.

Aquarium Setup

Maintain Black Tiger Dario in a structured tank setup with ample hiding spots. A soft substrate is preferred, but fine gravel works as well. Ideal plants include Cryptocoryne species and those that can be attached to decor like Microsorum or Anubias. Floating plants, driftwood branches, and leaf litter can also be incorporated. The tank should have multiple hiding spaces and plants, providing security for the fish.
