Abstract: Endemic fish species contribute 4% of the total freshwater ornamental fish exports in Sri Lanka. Most of them are collected from their natural habitats, wild population are depleting. Pethia reval is a newly described highly threatened, fish species endemic to Sri Lanka. This study was carried out to determine the best feed type out of Moina (T1), Ox – heart (T2) and Pellet feed (T3), to optimize the growth and reproductive performances of P. reval. Brooders P. reval were (total body length ranged from 20 to 25 mm) collected from Aththanagalu Oya, and stocked in cement tanks (5’x 3’x 3’) at NARA. Feed consumption, total body length and body weight of all brooders were recorded monthly. Acceptability of feeds was determined by visual observations.
