- "I caught a nibble fish! Do you regret nibbling now?"
An information board in the aquarium will provide information about this fish.
"The official name given to this warm-water-dwelling species of fish is "Garra rufa." They are omnivorous, as they both eat algae and scrape the skin off other fish. All you'd have to do to feed them is stick your hand in the tank; they would live off your dead skin. That's why they're called nibble fish. They exfoliate but don't have any teeth, so it doesn't hurt at all!"
In real life
The Doctor Fish, also known as the Nibble Fish, Kangal Fish, Physio Fish, Doctorfishen, or Reddish Log Sucker, is a fish that is used for medical purposes. They live and breed in the pools of some Turkish river systems and hot springs. They have been integrated as a spa treatment, where they feed on the dead skin of patients with psoriasis. While the treatment has been shown to alleviate symptoms, it does not cure psoriasis. The practice is banned in several United States and Canadian provinces as cosmetology regulators believe it's unsanitary.
In the wild, the Reddish Log Sucker occurs in the river basins of the Northern and Central Middle Easy, mainly in Turkey, Syria, Iraq, and Iran. It is legally protected from commercial exploitation in Turkey due to concerns of overharvesting for export.
During their activities of foraging, they slough off dead skin. They are simply looking for food which in the wild consists of aufwuchs (green algae and diatoms).
