Do Bala sharks need a certain amount of space?

Question

I dont mean space as in gallons i mean space as in too many decorations.

Answer 1

If you are talking about the silver and black bala sharks they can get pretty big and they are skiddish so if you have to many rocks and drift wood and such when they are swimming fast through the water they may hurt there selves on something in the tank but they do like to hide under drift wood and in plants.

Answer 2

Yes. I recommend for them to have at least 55 gallon tanks, but to keep a school of them, which is better, at least 150 gallons.
