Rasbora einthovenii
(Einthoven's Rasbora, Brilliant Rasbora) was named after a Dutch surgeon and
public health civil servant in Java during the colonial era.
This species inhabits slightly acidic, tropical forest streams, with a pH of
6.0 to 6.5. Its diet comprises worms, crustaceans and insects. (Fishbase,
2026). It is benthopelagic in habits i.e. it is active towards the bottom of
streams and in the overlying water column, but is typically not a surface
feeder.
Rasbora einthovenii occurs in Peninsular Malaysia, Singapore, parts
of Sumatra, the Riau Archipelago (including Pulau Sugi - see Figures 3 and
4), Bangka Island and parts of Borneo (Syarif et al, 2023, Lumbantobing,
2020).
