This is a very adaptable fish: able to be kept in unheated or heated aquaria, and in outdoor ponds. Can sometimes be aggressive towards tankmates such as fancy goldfish, but this varies with individual fish. The Paradise Fish has been popular as an aquarium fish since the 1860's, and a number of different aquarium varieties now exist. Males grow to about 7-8cm and the females remain slightly smaller. In nature, Paradise Fish are found from Korea, southwards to Vietnam.
