答案 Goldfish Because goldfish can be kept easily in small ponds and aquariums,/ they make good pets,/but like any other pets,/they must 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 oxygen will make its way into the water/of an aquarium/from the air that touches the surface ;/plants in an aquarium also help to furnish oxygen./Snails help to keep an aquarium clean./Thus, with plenty of plants and snails,/the water in an aquarium does not have to be changed frequently./ It is important that goldfish not be overfed./They can be fed such things as dried insects and shrimp/in addition to commercially-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.
