Glass perchlets or glassfishes are members of Ambassidae (Chandidae) family. They are distributed mainly in Asia and Oceania waters. They are identified as a family by their small and semi transparent body, and single and deeply notched dorsal fin. They are distinguished from cardinalfishes by having 3 anal spines besides a single dorsal fin.
Most species occur in shallow depth of coastal waters, mangrove shores and brackish estuaries, although some live entirely in fresh-water rivers. They are mostly nocturnal, spending the day among the roots of mangrove trees, log snags, and aquatic plants. They feed on small crustaceans, aquatic and terrestrial insects, and small fishes.
There are 8 genera and about 48 species worldwide. Malaysia is represented by 3 genera and about 12 species.
