Bala Shark - Balantiocheilos Melanopterus : Complete Fish Profile & Care Guide
Table of contents
Introduction
The Bala Shark (Balantiocheilos melanopterus) is a distinctive species of freshwater fish belonging to the family Cyprinidae. Native to the fast-flowing streams and rivers of Southeast Asia. Despite its common name, the Bala Shark is not a true shark but is so named because of its high dorsal fin and torpedo-like shape, which resemble those of marine sharks. Growing up to 14 inches in captivity, Balantiocheilos melanopterus requires a spacious aquarium to accommodate its size and active swimming habits. Thanks to their serene and resilient temperament, Bala Sharks make for excellent inhabitants in sizable specialised community aquariums. As these creatures mature, it is essential to recognize that they will eventually outgrow most tanks and will continue to grow for many years.
Bala Sharks, being a shoaling species, flourish in groups of six or more, provided they are housed in an aquarium of suitable size. It is critical to situate the aquarium in a tranquil area, away from high-traffic zones, to minimize stress on these fish, as they are prone to being easily startled. Additionally, ensuring the availability of ample shaded retreats within the tank is paramount for their sense of security.
Bala Sharks exhibit unique physical characteristics, including disproportionately large eyes and mouths in comparison to their torpedo-shaped bodies and silvery-grey scales that enhance their distinct appearance. Their pectoral fins, nearly invisible due to their transparency, contrast with the light grey or yellow tones of the dorsal, pelvic, caudal, and anal fins, which feature deep black edges. One of the most striking physical attributes of Bala Sharks is their large triangular-shaped dorsal fin, which sits almost perpendicular to their body. This, coupled with their substantial size potential, results in an appearance that is reminiscent of true sharks, further adding to their allure.

Sexual Dimorphism
Determining the sex of Bala Sharks can prove to be an arduous task, as external sexual dimorphism is usually indiscernible. However, during spawning season, it is worth noting that females tend to develop a more rounded belly in comparison to males.

Natural Habitat
Bala Sharks originate from Southeast Asia, where they grace the waters of medium to large lakes and rivers across Thailand, Borneo, Sumatra, and the Malay Peninsula. Regrettably, this species has experienced a marked decline in its natural habitat, leading to its rarity in many areas where it was once common, with certain regions even considering it extinct. The diminishing numbers of Bala Sharks can be attributed to a combination of overfishing, river damming, and environmental pollution, which collectively pose significant threats to their survival. Despite these adversities, the Bala Shark continues to captivate enthusiasts and researchers alike with its remarkable beauty and resilience.
Breeding
Breeding Bala Sharks in a home aquarium is a rare occurrence, as successful attempts are seldom documented. This can be attributed to several factors, such as the necessity for large tanks and a dearth of information regarding optimal breeding conditions. Notably, commercial breeders in Asia have managed to breed this species by employing hormone injections to stimulate spawning, although specific details regarding this process remain largely unidentified.
Diet & Feeding
Ensuring the optimal growth and development of Bala Sharks necessitates a comprehensive feeding regimen that includes a variety of nutrient-dense dietary options. Incorporating high-quality dry foods, including flakes, pellets, and granules, alongside live food sources such as artemia, daphnia, brine shrimp, and mussels, provides a robust foundation for their nutritional needs. To achieve a balanced diet, the incorporation of plant-based foods, including fruits, spinach, green peas, lettuce, and nettle leaves, is indispensable. This diverse dietary approach not only caters to their omnivorous feeding habits but also supports their health and vitality in a captive environment.
