Goldfish

Goldfish are domesticated freshwater fishes bred from Asian carp relatives, with forms ranging from streamlined pond fish to varieties with enlarged fins and altered body shapes. Their colors include orange, red, white and darker shades. They are distinct from koi, despite their shared ornamental use. Selective breeding has produced many recognizable varieties over a long history of fish keeping. Goldfish search for plant and animal foods using their mouths near surfaces and the bottom. Their diverse appearances reflect domestic breeding rather than separate wild species.
