Overhere some photos of the Forest halfbeak (Hemirhamphodon pogonognathus). It's endemic to South-East Asia. It looks quite similar to the Dermogenys pusillus. But the difference between them is that the Forest halfbeak has got a drooping appendage on the lower jaw and it's also larger than the Dermogenys pusillus. Mine are about 6cm as adults. Some claim that the max would be 4cm but mine have reached a bigger size.
