Also known as the tricolor shark or silver shark, the young bala
shark is a staple item in most aquarium stores. However, this fish is a
poor choice for most aquaria. The bala shark (the name is an
abbreviation of the scientific name) is active, grows to fourteen
inches, and prefers living in midwater shoals. So the typical community
aquarium is too small for keeping the bala shark long-term.
The bala shark is very peaceful. Even though this fish grows large,
it will not bother other fish—except those small enough to fit in its
mouth. Ideally, you should keep groups of six or more, but no less than
three.
