Any aquarium with tropical freshwater fish should have loaches.

They are typically calm scavengers who spend their time searching the aquarium bottom for scraps of food.

A lot of loach species prefer to be maintained in schools, and several species will sulk if kept alone.

Due to their hardiness and ease of maintenance, loaches are popular pets, and many owners find their gentle nature attractive.

Resist any kind of storm like a calm loach.
