[Ebook] The New Guide to Aquarium Fish – Brackish Water Fishes – The Asian Chromides
Two species of cichlid are found almost exclusively in brackish water: Etroplus suratensis (Green chromide, 45 cm (18 in)) and Etroplus maculatus (Orange chromide, 10 cm (4 in)). Both occur in coastal regions of southern India and Sri Lanka, chiefly in brackish estuaries and lagoons. The salinity of both types of habitat is variable, depending on the state of the tide and the fresh water input, which varies with the seasons.
