This order contains ricefishes, halfbeaks, needlefishes, flying fishes, etc.
Halfbeaks have the upper jaw much shorted than the lower jaw. Needlefish look like halfbeak, but can be told apart by the equal-lengthed jaws and the larger size. Ricefish do not have the streamline body of the rest and are much smaller.

There are two species of freshwater halfbeaks in Singapore. Pygmy Halfbeak is found in Western Catchment and Central Catchment, while Forest Halfbeak is found in Central Catchment1.
The Pygmy Halfbeak (Dermogenys collettei) belongs to the D. pusilla group. It lacks the drooping appendage of the Forest Halfbeak; and the dorsal fin starts after the anal fin.
The Forest Halfbeak (Hemirhamphodon pogonognathus) has a drooping appendage at the beak tip. Its dorsal fin starts before the anal fin.
The Stripe-nosed Halfbeak (Zenarchopterus buffonis) is common in rivers and has a prominent white spot on the beak tip.
The Spottail Needlefish (Strongylura strongylura) is identified by the black spot at the tail-base, while the Slender Needlefish (Strongylura leiura) lacks this.
