Research on larval production of Parrot red rainbow fish Glassolepis incisus has been done by using different numbers of raffia's rope as substrats for eggs attachment. A raffia's rope substrats of different plys concentrations namely A 360 plys, B 720 plys, and C 1080 plys were used. The spawning was carried out during 30 days, and larval feeding was given twice a day with frozen Chironomus larvae in ad satiation rate. The results showed that highest spawning frequencies was found in treatment

Highest eggs production were found on treatment A, B and C respectively at 1154 eggs, 892 eggs, and 691 eggs, respectively. Whiles the hatching rate were found that the treatment A = 92 %, treatment B= 85 % and treatment C= 94 %. The Treatment A overall was the best treatment in this experiment.
