About This Fish
The Red-Line Halfbeak “Sijuk” (Hemirhamphodon phaiosoma) is a rare freshwater halfbeak from Indonesia. It has a slender body, a long lower jaw, and a vivid red line that becomes especially noticeable once the fish settles into a dark, planted aquarium.
Unlike many commonly sold halfbeaks, this is a true soft-water species. It is best suited to experienced aquarists who can provide a mature blackwater-style aquarium, gentle tankmates, and plenty of room at the surface.

Received the Sijuk fish in perfect condition. After setting up my blackwater tank, the red line became very visible. It’s a striking addition to the community. Only recommend to those with experience in maintaining soft-water setups.

The fish arrived quickly and stayed active in the tank. I had to adjust the water parameters carefully, but it adapted well after a few weeks. A unique species that adds visual interest.
