Pet Trade

Introduced as pets from countries such as Indonesia and America, the Changeable lizard and the American bullfrog are now commonly seen in residential areas and reservoirs around Singapore. Alien freshwater fishes such as the Alien teleost fish, African cichlids from other parts of Asia and America and freshwater prawns such as the Macrobrachium lanchesteri from other parts of Asia such as Thailand, have now established itself in many freshwater bodies in Singapore. Birds such as the Feral pigeon, Javan myna and the commonly seen House crows were all introduced originally as pets in the past but have now caused significant disturbances and health concerns among residents due to their large populations.
