Introduction

Devario shanensis, commonly known as Hora Danio, is a peaceful and active species from the waterways of Myanmar (formerly Burma). Known for their vibrant coloration and energetic swimming patterns, these top-dwelling fish are ideal for community aquariums. While somewhat rare in the trade, their beauty and behavior make them a prized addition for experienced aquarists.

Food and Feeding

Hora Danios are not picky eaters and will accept most types of aquarium foods. Provide a quality flake food as their staple diet, supplemented with live or frozen treats like bloodworms, daphnia, or brine shrimp twice a week. This varied diet will ensure optimal health and vibrant coloration.

Habitat and Tank Requirements

To mimic their natural habitat, set up a spacious tank with plenty of open swimming areas and some planted zones along the sides. The water parameters should be maintained within a pH range of 6.6-7.3 and hardness of 3-16°N (53.57-285.71 ppm). The ideal water temperature is 21-28°C (69.8-82.4°F). Ensure good water flow and oxygenation, as they thrive in well-aerated environments.

Sexing

Females are generally plumper than males, especially during the breeding season. Males tend to have a more streamlined body shape.

Breeding

Breeding Devario shanensis can be challenging but achievable with proper preparation. Use a separate breeding tank equipped with spawning mops or Java moss to encourage egg deposition. Introduce a group of mixed-sex fish into the breeding tank. Spawning usually occurs at dawn, so be ready to remove the parents promptly after eggs are laid to prevent predation. Eggs typically hatch within 24 hours, and once the fry become free-swimming, they should be fed Infusoria or other suitable microscopic foods.

Lifespan

With proper care and an optimal environment, Devario shanensis can live up to 5 years in captivity.

Behavior and Compatibility

Hora Danios are peaceful and highly social fish, making them perfect for community tanks. They should be kept in groups of at least five to minimize stress and encourage natural schooling behavior. They coexist well with other non-aggressive species but may outcompete slower fish for food due to their active nature.

Short Description

As a rare gem in the aquarium trade, Devario shanensis (Hora Danio) commands a higher price than more common danio species. They are a lively and stunning addition to any tank, thriving in groups with ample swimming space and peaceful tank mates. Their rarity and vibrant presence make them a worthwhile investment for dedicated aquarists.
