由太子道至旺角道的一段通菜街北，是香港著名的「金魚街」，因為這裏有多間售賣各式觀賞魚類的店舖，儼如一個街邊水族館。
Since the competition is so big, the goods are cheap and have many choices, sometimes you can get a bag of tropical fishes with less than 20 Hong Kong dollars.
As time goes by, besides aquarium shops, the street has many pet shops now, so this is also a little zoo, even though you cannot have a pet, you can still look around, it is free anyway.
