Because goldfish can be kept easily in small ponds and aquariums, they make good pets, but like any other pets, theymust have proper care and the right kind of place to live. A two-inch fish requires a minimum of two gallons of water containing sufficient oxygen to support life. Some oxygenwill make its way into the water of an aquarium from the air that touches the surface. Plants in an aquarium also help tofurnish oxygen. Snails help to keep the aquarium clean. Thus, with plenty of plants and snails, the water in an aquariumdoes not have to be changed frequently. It is important that goldfish not to be overfed. They can be fed such things as dried insects and shrimps in addition tocommercially prepared goldfish food, but they should never be fed more than once a day. Even then, they should not be given more food than can be consumed in about five minutes.
