The true D. prosopotaenia ranges from Singapore to Sulawesi while the yellow-breasted variant ranges from Irian Jaya to eastern Australia and Vanuatu (Ref. 48636). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).
