Ambassis
Ambassis is a genus of fish in the family Ambassidae. These fish are commonly known as glass perches or glassy perchlets due to their translucent bodies. They are small, schooling fish that are found in freshwater, brackish, and marine environments throughout the Indo-Pacific region.
Characteristics
Members of the genus Ambassis are characterized by their elongated, compressed bodies with a slightly rounded snout. They have a single dorsal fin, with a distinct spiny anterior portion and a soft, rayed posterior portion. Their scales are small and cycloid (smooth and rounded). The coloration of Ambassis species is generally silvery or pale, with some species exhibiting darker bands or spots.
Environments
Ambassis species inhabit a wide range of environments, including estuaries, mangroves, rivers, lakes, and coastal waters. They are often found in areas with dense vegetation or rocky substrates. They are typically schooling fish, forming large aggregations that can be seen in shallow waters.
Diet
Ambassis are primarily insectivores, feeding on small insects, crustaceans, and other invertebrates. They are opportunistic feeders and will readily consume a variety of prey items.
Reproduction
Ambassis species are oviparous, meaning they lay eggs. The females release eggs into the water column, where they are fertilized by the males. Eggs are often laid in clumps or attached to vegetation. The larvae are planktonic and drift with the currents until they develop into juveniles.
Species
There are over 20 recognized species of Ambassis. Some of the most common species include:
- Ambassis ambassis (Common Glass Perchlet)
- Ambassis gymnocephalus (Gymnocranium Glass Perchlet)
- Ambassis interrupta (Interrupted Glass Perchlet)
- Ambassis macleayi (Macleay's Glass Perchlet)
- Ambassis nalua (Nalu Glass Perchlet)
