答案
Hello.Today I'd like to tell you about the fantail goldfish. Fatail goldfish can live a long time if you look after them carefully. You must make sure their water is clean and you mustn't pick them up with your hands. You should not put them in the sun.
You should feed them special fish food every day. Sometimes, they eat vegetables too. My fantail goldfish likes to eat peas.
When a fantail goldfish grows up, it can be 20 cm long and weigh about 400 grams. The body of a fantail goldfish is something like an egg. Most fantail goldfish are orange, but sometimes they are black, white or green. They have long, beautiful fins.
Fantail goldfish are nice pets because they're quiet and easy to look after and they aren't expensive to buy.
