Dorsale stekels (totaal) : 3 - 4; Dorsale zachte stralen (totaal) : 5 - 6; Anale stekels: 1; Anale zachte stralen: 10 - 12. Predorsal scale count 14 to 17. Sexual dimorphism not apparent in this species.
Found in mangrove swamps and saline creeks (Ref. 9786, 44894). Occurs infringing coastal mangroves in brackish or marine waters. Aggregations shelter among submerged roots or inundated leaves and branches (Ref. 44894). This is a planktivorous species which adapts well to freshwater environment. May occur in large schools, frequently in muddy waters. Sympatric with P. cyanodorsalis over part of its range (Ref. 9786). Probably more widespread, but has escaped notice due to its small size and largely inaccessible habitat (Ref. 44894).
