Stripe-nosed Halfbeak (Zenarchopterus buffonis)
Sungei Buloh, 22nd July 2014

This Stripe-nosed Halfbeak was one of many casualties of a mass mortality event that killed off large numbers of several species of fishes in one of the tidal ponds at Sungei Buloh. The hot weather, combined with the neap tide, likely led to a drop in the dissolved oxygen content that most fishes could not tolerate.

Fortunately, this was an isolated incident that did not affect fishes in the other parts of the reserve, and this particular pond has since been repopulated.
