How do cleaner fish run underwater 'cleaning stations'?
Deep on the coral reef, something strange is happening. A huge grouper — big enough to swallow a basketball — opens its mouth wide and just… waits. A tiny striped fish, no bigger than your thumb, swims right inside. But this isn't lunch. This is an appointment.
The little fish is a cleaner wrasse, and it runs an underwater cleaning station — like a car wash, but for fish. Big fish swim up when they're itchy, covered in parasites, or have bits of dead skin they can't reach. The cleaner wrasse nibbles it all off. The big fish gets clean. The wrasse gets breakfast. Everyone's happy.
