Habitat: Freshwater, brackish water,
estuaries and lagoons; mangrove areas.
Description: In this species, length
of caudal peduncle is 0.6–0.9 times its
depth. Melanic areas are usually present on lower parts of head, on cleithrum,
and on apices of caudal and soft dorsal
fins in adults. Occasional irregular and
asymmetrical spots are seen on flanks,
probably representing vertical bars. The
median spot or transverse bar noticed
on the nape is rather constant. This
species grows to a maximum size of
28 cm (Torres, 1991p).
