The double-hole fish is commonly known as moss fish, pipe fish, moss rat, algae-eating fish, and scavenger.
The mouth of the amphipod is shaped like a sucker, so that it can be adsorbed on surfaces such as rocks and eat algae on the surface of the rocks. Raised as an ornamental fish in an aquarium, it can shovel moss, algae, etc. on the surface of the glass and the bottom of the tank to make the water clear and the glass bright, so it is called a "scavenger" or "algae-eating fish".
The fish has a docile temperament and is easy to raise. In the aquarium, the water quality is weakly alkaline (PH is about 7.3) and the suitable water temperature is 23-28°C. When raising it, feed it an appropriate amount of chopped vegetable leaves.
The fish is native to the Mekong River Basin and is now raised as an ornamental fish all over the world.
