Hemirhamphodon pogonognathus

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.

Actually, they get much larger than that. Fishbase gives 10cm as max, which is about 4 inches. However, I recall seeing them at Jim Langhammer's house, and his were easily 6 inches (15cm). Also, the fish in your photos are not showing mature male coloration and finnage. I may have a slide somewhere, but my slides are very jumbled up at the moment.

It depends on the how the light hits the fins that you're able to see some color in there. In these pics it's not that clear. I haven't had adults that became bigger. But who knows... maybe some day, they'll become the size you've been mentioning.
