Doctor Fish (Garra rufa)

The Garra Rufa, commonly known as the Doctor Fish, is a hardy and active freshwater fish recognized for its algae-grazing behavior and constant activity. It has an elongated body with a sucker-type mouth that allows it to graze on algae, biofilm, and organic matter from rocks, glass, and decorations. This species is widely known in the aquarium hobby for its interesting behavior and usefulness in keeping aquariums clean.

Garra Rufa thrives in aquariums with good water movement, clean water, and plenty of rocks or surfaces for grazing. It is generally peaceful but active, making it suitable for larger community aquariums with similarly sized fish.
