In olden day Singapore, at a time where life was much simpler, children regularly turned to nature as a source of entertainment.
One such activity was drain, or longkang (Malay word for drain) fishing. Children would catch small fishes such as guppies or mollies using small handheld nets. A good time to go drain fishing would be just after a rain, as the flooded drains are usually full of small fishes after that. Some lucky fishes are kept as pets in proper home aquariums, most suffer at the hands of their child captors. Catching fighting spiders and grasshoppers were just as popular.
