Caring For Goldfish
in China, goldfish (Carassius
auratus) are a popular choice of pet, especially

maintenance and easy to care for. Despite their name, they come
in many shapes, sizes and colours. They can grow
up to 20cm and live between 10-20 years.

enough to kill all the fish, so do set up the
tank a few days prior. Place the aquarium on
either a stand or a sturdy piece of furniture,
it should be out of direct sunlight.

to hide so it is always a good idea to put in a
