You
must care for your fish to make sure they stay healthy.
Feed them the right amounts of food and change the water
monthly or when it looks cloudy to keep the tank clean.
Depending on the kind of fish, the water may need to be
tested for pH, ammonia and nitrites. Your pet store may
offer a service to test the water if you bring in a
small sample or you may purchase a test kit which comes
with instructions to test the water at home.
