Bala Shark Complete Care – Everything You Need To Know

Species Summary

The Bala Shark (Balantiocheilos melanopterus ) is a freshwater fish native to Southeast Asian countries including Thailand, Sumatra and Cambodia, where they inhabit fast-flowing lakes, rivers and streams. Unfortunately, in 1996, the IUCN marked Bala Sharks as endangered. The population size was unspecified, so more research is needed, but it is believed that they are already extinct in Borneo due to overfishing and natural wildfires.

It has several names including Silver Bala, Silver Shark and Tricolor Shark. Don’t be fooled by the name though! They aren’t really sharks and they are not at all aggressive. They get the shark part of their name from the shape of their bodies.

Availability

Although Balas are listed as an endangered species in their wild habitats, they are readily available within the fish keeping trade thanks to carefully managed breeding facilities. In the UK, Silver Sharks tend to retail around £5, whereas the US is $5 for smaller Balas and up to $10 for larger individuals.

Bala Shark Lifespan

If kept in good water conditions and fed a high-quality diet, these fish can live a long time. The average lifespan for an aquarium Silver Bala is 10 years.

Appearance

Silver Balas are striking fish for many reasons. They tend to be 3 to 4 inches when purchased from aquarium stores, but they will grow to an adult size of 12-13 inches. These freshwater fish have prominent silver scales. Their yellow tail and black-tipped fins makes them even more beautiful.

Like marine sharks, Balas have a tall dorsal fin, a long body tapered at the tail and a downturned mouth.

Bala Shark Tank

This is an active fish that can grow quite large, so they need plenty of room. They are a schooling fish and swim actively, therefore a long tank is more suitable. They tend to jump when startled, so a tank lid is a must to prevent any accidents.

Silver Balas should be kept in a tank of at least 125 gallons (473 litres) which is roughly 6 feet long. This will give them the required surface area to swim in. Balas are best kept in groups of 4 or 5, so a smaller tank would not be suitable.

Substrate

Since Silver Sharks are native to freshwater rivers and streams, a substrate of various sizes pebbles is closest to their natural environment, however, you should also consider the requirements of any other fish sharing the same aquarium.

You can use a finer aquarium sand as a base layer and added a scattering of pebbles and small rocks to add texture and a more natural appearance. Balas do not spend time near the bottom of the tank, so your decision should be based on other species and personal preference.

Plants and Decorations

Since Bala Sharks need a lot of room to swim, tall plants should be kept away from the middle of the tank. Crypts and Anubias can grow quite tall, so should be planted in the background or edges of your aquarium. Their height adds nice definition to your set-up and provides shelter for other fish in the tank.

Java moss is an easy plant that will spread to carpet the substrate. You will need to trim it regularly to prevent it getting too tall.

Since Balas are prone to jumping when scared, you can also include some surface plant such as duckweed, water lettuce and hornwort. These are fast growing plants so you will need to trim them back regularly. They will create a natural barrier to prevent any accidental escapes.

Decorations such as stones, driftwood and spider wood will all add natural detail to your aquarium.

Temperature

The tropical biome of Southeast Asia means your Bala Shark tank should be kept around 77°F (25°C) but 1 or 2 degrees either way fine. For a large tank you will need a heater of 375 watts as a minimum. To keep an eye on the tank temperature, you should install a thermometer in your tank, on the opposite side to the heater.

Lighting

You will not need any specific lighting for Silver Sharks. A simple freshwater aquarium lamp with be sufficient. Be mindful of other fish sharing the same tank and also the light requirements of the plants you are keeping.

You should maintain a regular day and night schedule by keeping lighting on during the day for at least 8 or 9 hours, then switching the lighting off during the night.

Cleaning and Water Parameters

The ideal pH for your Bala Sharks is between 6.5 and 8, with a water hardness between 10 and 13. You should do weekly water tests when first setting up the tank to make sure the filtration is working correctly. Remember to add tap safe (dechlorinator) to your aquarium when first setting up.

To maintain healthy water parameters, a 20-30% water change should be done every 2-3 weeks. Bala Sharks are sensitive to changes in water parameters such as Ammonia and Nitrite levels, so you should also invest in a high-quality filtration system capable to cycling a large aquarium.

Since your Balas are native to fast-flowing rivers, your filter will need to generate moderate water movement at least in one area of the tank.

Bala Shark Health

As far as diseases go, Bala Sharks are not susceptible to any particular illnesses. They are, however, sensitive to changes in water parameters, so it is important that temperature, pH and ammonia levels are checked regularly.

Like any fish, they are susceptible to common complaints such as Ich and parasites. If you notice that your Bala are ill, consult your local aquarium dealer. They will be able to advise on the best treatment.

A poor diet can cause digestive issues, which is why it is important to feed them a high-quality diet.

High quality fish flakes or pellets should make up the main part of their diet. Additionally, you should provide them with protein rich food like shrimp or bloodworms. You call also give them finely chopped spinach.

Balas are prone to overeating, so they should be fed 2 smaller feeds daily. Do not put more food in than they can eat in 3 or 4 minutes.

Behavior & Temperament

Your Bala Sharks are a great addition as they are active swimmers and will school together with other Bala Sharks. They are a peaceful fish with other species of a similar size, but can show aggression to smaller fish.

Bala Sharks are a schooling fish so should be kept in a group of at least four individuals, provided your aquarium is large enough.
