When you tap on the glass of the tank, they feel it. Hope this helps!
lateral line is a line on the fish body that function to detect vibrations in water
The lateral line of a fish detects vibrations in the water and transmits them to the brain. The external ear in humans detects vibrations in air, water, and solids and transmits them to the brain.

a Seismograph measure earthquake vibrations
It detects ground vibrations.
A seismometer detects the earthquake vibrations that the seismograph records.
Vibrations and their giant ears.
The instrument that detects, measures, and records the energy of earthquake vibrations is called a seismometer or seismograph.
Well, I Think The Tail.
Perch fish are carnivorous and primarily feed on smaller fish, insects, crustaceans, and zooplankton. They use a combination of hunting techniques such as ambush predation, chasing down prey, and scavenging. Perch have well-developed sensory organs, including keen eyesight and a lateral line system that detects vibrations in the water, helping them locate and capture their prey efficiently.
A swim bladder is an internal gas-filled organ that helps fish control their buoyancy, while a lateral line is a system of sensory organs along the sides of a fish that detects changes in water pressure and vibrations, helping fish sense their surroundings and detect movement.
Fish possess several senses that help them navigate and survive in their aquatic environments. They have well-developed vision, which allows them to see in various light conditions, and many species can detect polarized light. Additionally, fish have a keen sense of smell, enabling them to detect chemicals in the water. They also possess a lateral line system, which detects vibrations and movement in the surrounding water, and some can sense electrical fields through specialized organs.
