Bala Shark

Balantiocheilos melanopterus

Overview

Bala Sharks are one of the most impressive fish you can add to a large community tank. Despite their name and shark-like appearance, they are peaceful schooling fish that bring energy and movement to any setup. They get big, often reaching 12 inches, and need to be kept in groups of six or more. The biggest mistake people make with Bala Sharks is underestimating how big they get and how much swimming space they need. These are active fish that need a large tank. When properly kept, they are elegant, peaceful, and endlessly entertaining.

Tank Setup

A 75-gallon tank is the absolute minimum for a small school of Bala Sharks, but 125 gallons is ideal. They are active swimmers that need plenty of horizontal swimming space. They are also jumpers, so a secure lid is essential. Provide a substrate of sand or gravel and some plants and décor for security, but keep most of the tank open for swimming. A powerful filter is important because these are messy eaters. They prefer some current, mimicking their native river environments.

Water Parameters

Bala Sharks are adaptable to a range of conditions. They do well in temperatures between 72-82°F, with 77 being ideal. pH can range from 6.0 to 8.0, which covers most tap water. They are not particularly sensitive to water parameters, but they do best in clean water. Weekly water changes of 25-30% will keep them healthy. They come from rivers in Southeast Asia, so they appreciate moderate water movement from the filter.

Diet & Feeding

Bala Sharks are omnivores that are not picky. Quality flakes or pellets should be the staple. They eagerly accept most foods, including flakes, pellets, frozen bloodworms, brine shrimp, and daphnia. They also enjoy blanched vegetables like zucchini and spinach. As they grow, their appetite increases. Feed 2-3 times daily, only what they can consume in a few minutes. They are active fish with high metabolisms.

Behavior & Temperament

Bala Sharks are peaceful schooling fish that need groups of at least six to feel secure. They are active swimmers that love to chase each other around the tank. They are generally peaceful and get along with most community fish. They may be shy at first in a new tank, but will become more confident as they settle in. They are not aggressive and will not bother tankmates. They may jump when startled, so keep the tank covered.

Compatible Tankmates

Bala Sharks work well in large community tanks with other peaceful fish. They can be kept with tetras, rasboras, corydoras, danios, gouramis, and other large community fish. They are safe with other Bala Sharks and similar-sized fish. Avoid keeping them with large, aggressive fish like oscars or cichlids that might eat them. They are also not suitable for tanks with very small fish that could be seen as food.

Common Health Issues

Bala Sharks are generally hardy fish. The most common health issue is ich, which appears as white spots on the body, usually triggered by stress or poor water quality. Treat by raising temperature to 80°F and using ich medication. They can also be prone to bacterial infections if water quality is poor. Watch for signs like lethargy, loss of appetite, or unusual behavior. They are also prone to skin flukes, which can be treated with appropriate medication.

Breeding

Bbreeding Bala Sharks in home aquariums is extremely difficult. They require very large tanks and specific conditions to spawn. They are egg-scatterers, but distinguishing males from females is challenging. Most Bala Sharks in the hobby are commercially bred. If breeding occurs, the parents will eat the eggs, so they should be removed. Raising the fry is challenging because they need very fine foods initially.
