観賞魚











鯉


観賞魚（かんしょうぎょ、鑑賞魚とも）とは、人間に憩いを与えるために水槽や庭に設けた池などでペットとして飼育される魚類の総称である。


魚は水域で採集すれば入手できるが、居住域以外の魚を入手するには観賞魚専門店やペットショップの観賞魚コーナーで購入する必要がある。食用に古くから漁獲され、また養殖されてきた魚の美麗な変異個体を選抜したものに金魚や錦鯉があり、また熱帯地方には多種多彩な観賞価値の高い美麗であったり珍奇な形態をした魚が多く、熱帯魚の呼称で古くから観賞魚の主要なジャンルを構成してきた。


大きく淡水魚と海水魚に分けられるが、海水魚の方が飼育が難しい。また、淡水魚でも人工的に作られた金魚・錦鯉などは野生種と区別される。
