to be 20 centimetres long and weigh up to 400 grams. Some are black and others are
orange. They are easy to look after. They eat special fish food and sometimes eat
vegetables. I feed them once a day. I put them in clean water. They don't make any
trouble.
They are very quiet, and they never make any noise. I like watching them swim
around. And my pet goldfish can always make me happy. We are good friends.
