      Do you keep pet fish at home? It is fun to keep pet fish. I have got a tank, the tank has two fish in it. one is

a goldfish, and the other is an angel fish. the angel fish has black stripes. it looks prettier than the goldfish. I feel

happy when I look at them. I usually look at them when I have something unhappy or feel tired.

      I always keep the water in the tank clean, because both the goldfish and the angel fish like clean water. They

can't live in dirty water. In winter, I need a heater in order to keep water warm. The angel fish doesn't like cold

water. I only feed the fish once a day. Too much food may make the fish die.
