Origin: The ancestors of our Bala Sharks originally lived in the Malay Peninsula, Sumatra, and Borneo, but now they're raised on fish farms and found living in aquariums throughout most of the world.

Maximum Size: In aquariums they can grow to be about 14" long, which is too big for most home aquariums.

We estimate that a few of them would need an aquarium with at least 240-gallon water, and bigger would be better.

Behaviors: this fish species is a very active swimmer that's not aggressive.

It's important to always keep their aquarium tightly covered, because Bala Sharks are very skillful jumpers.

Compatibility: Some recommended tank mates include, Rainbowfish, Clown Loaches, Danios, Barbs, Gouramis, and many other medium size aquarium fish.

Temperature: Balas can live pretty well from about 70 to 80 degrees F., but they're probably most comfortable at about 75 to 78 degrees F.

Feeding: Premium Fish Food Flakes when small and Premium Pellet Food when larger.

Water Conditions: Bala Sharks seem to be tolerant of a wide range of water conditions.

Probably a pH of about 7 with moderate hardness is best.

Most water in the US has a higher pH and is harder but seems to be OK, so it's probably best NOT to adjust the pH or the hardness of the water.

Here in our facilities the water is hard and the pH is usually about 7.8.

We ship them in this water.

Aquarium Size: When young and less than 3" long, it's probably best to house them in at least a 30-gallon aquarium, but bigger is better.

Later when they grow bigger, they'll need a much bigger aquarium, probably bigger than most aquarists have available.

Decor: Bala Sharks do not need gravel, and a layer of gravel more than 1/4" thick will usually fill with bits of uneaten food that will contaminate the water.

Live Plants: are beautiful and improve the water quality. Bala Sharks enjoy live plants.

Aquarium Filter: Bio-Wheel Filters are highly recommended.

A Penguin 200B Filter in an aquarium with 30-gallons of water is OK, when they're small, but a Penguin 350B Filter is the right size for a 30 to 60-gallon aquarium.

When Balas grow to be over 10" long, they'll need to live in aquarium with at least 150-gallons of water and have have as many Penguin 350B Filters as will fit along the back edge of the aquarium.

The addition of Lava Rocks will keep nitrates in the ideal range.

Life Span: Bala Sharks live for several years and possibly many years with excellent water and premium food.

Gender: It's not easy to tell the males from the females, when they're young, and sometimes even as they mature.

As females mature they often fill with egg and become plumper, which may be a clue to their gender.

Breeding: Bala Sharks scatter a large number of eggs on plants or special breeding mops made of nylon yarn.

But because of their large mature size they rarely spawn in aquariums.

Popularity: Bala Sharks have been one of the most popular aquarium fish for many years, and they're still very popular.

Names: The scientific name of the Bala Shark is Balantiocheilos melanopterus.

Variations: We know of only one type of Bala Shark and no variations.
