Sharks love to swim. So other than eating and hunting fish, they swim. If they dont do that than they just hunt and eat all day.
Sharks are fish so, like all fish, they have scales. In the case of sharks, these scales are somewhat different in composition, and actually make up a yep of skin. Shark skin is made up of tiny, hard, tooth-like structures known as dermal denticles or placoid scales.

Bala sharks grow into large fish. The basic rules are. :- 1 inch of fish needs at least 1 gallon of water (a single Bala shark needs at least 20 gallons. 2 need around 40+gallons). Every tank needs a permanently running cycled filter. Every tank needs to have at least 50% of its water changed every week. Different species of fish need different temperatures (Bala sharks need around 75F) and different pH and specialised foods if required (Bala sharks are omnivorous). If you supply your fish with the above they should survive reasonably well. If you fail to supply what is required to keep your fish healthy I can guarantee that your fish will never be healthy and they will be a source of constant worry.
