Description: The wrestling halfbeak is a very interesting fish with a long "beak" and silver and red coloring. Halfbeaks are extremely nervous, so not clean the algae from the back and sides of the tank as this helps calm the fish. Floating plants can also help calm this fish. The use of opaque glass can help if algae is not growing readily on the clear glass. This fish does best in brackish water with a specific gravity of 1.008-1.018, although in the wild it is occasionally found in pure freshwater or coastal reefs. Brackish water is necessary for the long term survival of this fish.
