Sucker fish, commonly known as plecos or plecostomus, belong to the family Loricariidae and are popular freshwater fish often kept in aquariums. They are known for their sucker-like mouths, which they use to attach to surfaces and feed on algae and other debris, making them helpful for maintaining a clean tank.
Plecos are peaceful fish but require a lot of space and proper care. They are nocturnal and prefer hiding spots during the day. It’s important to ensure they have access to enough food, including sinking algae wafers or vegetables, especially in clean tanks where natural algae may be limited.
