Loaches: The Efficient Extractors

Loaches have developed a finesse for all things snail. These sneaky loach species like clown loaches, zebra loaches, and dwarf chain loaches have a knack for targeting snails.

Meanwhile, catfish, including the talking catfish, spotted catfish, and striped catfish, roam their watery domain at night, adding snails to their menu. They're nocturnal and secretive, almost like the Batman of the aquarium world!
