Flying barb

Adults reach 6–7 cm in length. The flying barb has an elongated, streamlined body and large, pointed fins positioned toward the tail. The pectoral fins are notably wing-like in size and placement. This is fitting, as the fish earned its name from its ability to leap out of the water and briefly glide through the air—though it does not match the South American hatchetfish in this skill. The body is usually grey with a silvery belly, and two stripes run along the body: one black and one golden. Sexual dimorphism is weak; males are typically slimmer and slightly smaller than females.

This species is native to much of South Asia, including Pakistan, Nepal, Myanmar, Bangladesh, much of India, and Sri Lanka. In nature, flying barbs prefer shallow river and stream sections, swamps, and tropical forests flooded during the monsoon season. They are often found where aquatic plants are abundant.

The flying barb is peaceful and prefers to live in a group. Note that this is not a true schooling species; instead, a complex hierarchy develops within the group. Keep a minimum group of 8–10 individuals to prevent aggression from dominant fish, which can occur in smaller numbers. Such hostility may sometimes extend to other tank mates. Good companions are peaceful species of similar size, such as danios, barbs, and other cyprinids.

A group of 8–10 flying barbs needs a tank of at least 200–250 litres. Since these fish inhabit the upper water layers, pay attention to surface area as well as depth. Use a dark substrate and provide plenty of plants and driftwood as shelter. A secure lid is essential, as this fish can jump. The species adapts well to various conditions and is easy to keep, as shown by its survival in flooded rice fields in nature. However, do not neglect regular maintenance: perform partial water changes weekly and remove food waste and excrement. Being omnivorous, flying barbs readily accept most popular foods in dry, frozen, and live forms. Floating pellets are best, since food that sinks to the bottom is often ignored.

Breeding flying barbs in the aquarium is moderately difficult. A separate tank is needed, as these fish eat their own eggs. Simulate the monsoon season by performing frequent water changes with softer water and gradually raising the temperature toward the upper end of the recommended range. Spawning is typically in pairs or groups, with females scattering small eggs among fine-leaved plants. Remove the parents immediately after spawning. Incubation and fry development follow the standard pattern for cyprinids. The first food for fry is infusoria and microworms; as they grow, transition them to brine shrimp nauplii.

This species is prone to a specific condition called 'wasting syndrome', marked by rapid loss of muscle mass. No effective treatment is currently known. Otherwise, the fish have a strong immune system when water quality is maintained and stress is minimized.

When selecting individuals, watch for activity: healthy flying barbs should be active and occupy the upper water layers. Avoid fish with damaged fins, as they are prone to infighting when hierarchies are disrupted or group size is too small. It is best to buy a school of 8–10 individuals at once to reduce stress during acclimation.
