Dermogenys collettei is a species of viviparous halfbeak found in freshwater areas in Thailand, Malaysia, Singapore, and Indonesia.

[2] This species was described in 2001 by Amy Downing Meisner with the type locality given as Kuching in Sarawak.

[3] The specific name honours the American ichthyologist Bruce Baden Collette.

However, contrary to predictions, they exhibited this behavior in low predation scenarios, forest stream habitats in low predation, and more open stream habitats.

[5] Their behavior suggests that adaptive responses to immediate predation risk are absent.
