In the city aquariums ......?

Question

why do the sharks not eat the little fish? AND how are the waters always that pretty color blue?

Answer 1

The sharks can and sometimes do eat the little fish. Two things limit the predation. First the sharks are kept WELL fed, and second the aquarium is large enough to give the little fish room to escape. The water is kept clean by proper filtration, and it is NOT over populated.

Answer 2

if the sharks get fed well, they wont hunt for the other fish, and for the water, its filtered and cleaned, or its just taking the color form the ground or walls..

Answer 3

If you keep a shark fed he will not go hunting for food.

As for the water, it is filtered, treated and monitored.
