Courtship behaviour, captive breeding, embryonic and larval developments of Nemateleotris decora and its rearing with suitable live feed were described. Different age groups (60–100 mm TL) were stocked (glass aquaria, 500 L) in outdoor transparent roofed hatchery at water temperature 29 ± 1 °C for pair formation. After 6 months of rearing, 4 pairs were formed. The size of the female ranged from 60 to 90 mm and males from 90 to 100 mm. Each pair was then stocked in 250-L perspex breeding tanks in the indoor breeding unit with a photoperiod of 14 L: 10 D by a 40-W bulb suspended at 20 cm above the water surface. The environmental parameters such as temperature, salinity, dissolved oxygen and pH, NO2, NO3 and NH3 were maintained at suitable levels and monitored once in 24 h. The pairs were daily fed with cooked meat of squid, shrimp, green mussel, raw fish egg mass at 10% of their body weight in four split doses and live adult artemia (10–15 per day). The pairs began to spawn after 6 months acquisition in the breeding tanks. Each spawning consisted of 400 to 500 eggs, which were elliptical in shape with a length of 1.1 ± 0.1 mm and a maximum width of 0.4 mm
