Balas are endangered and almost extinct in the wild. The majority of the
hobby sharks are captive on farms because of this. I used to work at an
aquarium and they had a great fact sheets about it...

The bicolor shark is even extinct in the wild.

The bala, like the bicolor and the pakistan botia and a *bunch* of
other fish are facing extinction because of the booming asian
population and associated problems (development, water shortage,
pollution, overfishing, etc etc etc).

However, to the best of my knowledge, bala sharks have never been bred
in captivity without hormone injections, so it is highly unlikely that
the OP will get a bunch of bala babies.
