Body brownish, grey-yellow to grey-violet with 7 to 11 dark diagonal stripes diagonales on the flanks. 2 to 3 black spots or short stripes at the base of the caudal. First dorsal with a black mark and a white stripe on its superior margin, base of the second dorsal sometimes with 1 or 2 raws of elongated grey or black marks. Caudal and pelvic usually hyalin to greyish. One striking black mark at the base of the pectorals. Head with several iregular red and blue stripes. Up to 6cm SL (Ref. 57749).
Mainly recorded from mangroves and estuaries, but also found in coastal freshwater streams (Ref. 43716).
