The Glassfish are a popular and exotic species. Glassfish get their name from their translucent body. Their body resembles glass in the sense that you can see their bones and internal organs. They are hardy, and make good fish for beginning aquarists. They are also popular among experienced aquarists as well. Glassfish are a peaceful fish and will fit well into most brackish communities. They have been known, however, to get territorial towards other aggressive fish. If kept in groups, Glassfish will school with each other. They like to stick to the bottom of the tank. Glassfish should be kept in large aquariums with heavy vegetation and rocks. They should have plenty of space to swim however, as the Glassfish is quite active.
