In a word, Golden Beard is not a scavenger, but an alien scaleless fish, native to South America, mainly distributed in gentle and beautiful places, and is also an expert in algae removal in fish tanks.
Their body size also determines their tooth structure, which is more suitable for vegetarianism, rather than eating mucus on the surface of other fish when they grow up. The tank wall in the fish tank is covered with algae, and it is only 4-5 cm in size to put two moustaches in it. In a few days, the tank wall will be clean, and then you can see that the bearded fish belly is covered with blue-brown algae and moss.
