Algae and moss on walls and decorations. Sometimes they stand with their heads down and are intent on "working", sometimes they take a break from the busy work and swim quickly to the water surface, using their special respiratory organs and other special assisting respiratory organs to breathe the air on the water through their large mouths. Even so, the kissing fish It is so tiring, but it is still not a good "aquarium scavenger", because although they like to eat algae, it is not their staple food. Crossing fish eat a lot of food and can hand over all the bait, but there is no need to eat algae. However, due to its natural endowment and the large amount of physical energy it consumes due to its active habits, as it grows and develops, its infiltration will also decrease significantly, almost more than the dirt it "removes"!
