Dermogenys pusilla

The Halfbeak is an unusual surface dwelling fish with an obvious 'beak' like mouth appendage. The fish is timid at first and prone to damaging its mouth during quick flights when startled. Once settled in a tank the fish is more confident and lively. Surface floating plants should be provided as cover. The fish will benefit from a little salt added to the water, and can also be kept in brackish water. Keep with other peaceful fishes
