Telmatherina Ladigesi
he celebes rainbowfish (Marosatherina ladigesi) is a species of sailfin silverside endemic to Indonesia. It is the only known member of its genus. Males grow to 6-8cm, and females to 5-7cm in length. Their bodies are slender and almost fully transparent with a blue stripe along the sideline. The sexes can be easily distinguished, since males have elongated black dorsal and ventral fins, and are usually a little darker than females.Marosatherina ladigesi is found only near the town of Maros from which the genus name Marosatherina is derived. Due to ornamental fish business and pollution, their numbers have dramatically reduced.These fish dwell in estuaries, where freshwater rivers flow into the sea, so they live in fast flowing brackish water with lots of dissolved oxygen. Most of their day is spent hiding among the leaves of plants, where they eat small worms, insects or vegetable debris.
