Prefers slow-moving streams. The species in uncommon in Hong Kong. Inhabits mainly waters of lowlands and brackish water, and also known to inhabit tidepools of coasts of certain regions in Japan and Korea. Withstands a wide range of salinity (Ref. 58933). For indoor culture, a diluted sea water is rather better than the freshwater , and the use of a balanced salt solution is recommended, if the tap water proves to be unsuitable (Ref. 58933). Ominovorous (Ref. 58933). Feeds on zooplankton. Used in experimental research (Ref. 4537). In the experiment, fish were fed a combination of live brine shrimp and flake food, twice daily (Ref. 39708).
As live foods, certain aquatic worms (Tubifex, Limnodrilus) and the white worm (Enchytraeus) are adequate. The ideal live foods for both adults and young are certain water fleas (Entomostraca) and nauplii of the brine shrimp (Artemia salina). Among water fleas, Moina macrocopa has proved to be the best. It is smaller than Daphnia, so that it is readily taken by the fish. Although adult Moina cannot be eaten by larvae, it is recommended that they be put in the containers, because tiny larvae of Moina, which are parthenogenetically produced, are easily eaten by juvenile fish (Ref. 58933). |
