Hemigrammus rodwayi Durbin

( Fig. 49 , SA[SPC])

References. Admin, 2006.

Distribution. Sungei Buloh Wetland Reserve (Chim CK, pers. comm., 2006); Kranji Reservoir ( Admin, 2006, identified as Chanda sp. ; Lim RHB, pers. comm., 2018); Murai Reservoir (Lim RHB, pers. comm., 2018).

Remarks. The first record of this species (deposited in ZRC in 2006) was from a brackish water pond at Sungei Buloh Wetland Reserve and could have been flushed out from one of the fish farms adjacent to the reserve (Tan HH, pers. obs.). In 2006, and more recently in 2018, this species has been observed in large schools in Kranji and Murai Reservoir ( Admin, 2006; Lim RHB, pers. obs.). This fish has been occasionally found in waters with varying degrees of salinity ( Froese, 2018). The persistence of this fish in Kranji Reservoir from 2006 to present suggests that it has established a viable breeding population.
