The other part of it is that it’s a non-event event when they do bump into each other. Both are fish, so it’s highly unlikely one’s going to spin out and drown. They live moving in water like we live moving around in air.
Do fish ever crash into each other?
Summary: Swimming fish do not appear to use their collision warning system in the same way as flying insects, according to new research that has compared how zebra fish and bumblebees avoid collisions. The fish surprised the researchers.
Why is it that fish swimming together never run into each other?
Groups of birds and fish may harness fluid dynamics to keep just the right distance from each other. By surfing in the wake of individuals up ahead, schooling fish and flocking birds can keep pace with their leaders—even without mimicking their every move. …
Why do fish bump into each other?
They bump into each other all the time, then. Moving fast, trying to follow the current, walls on both sides of you, it’s pretty chaotic. Many fish have a line of sense organs along each side, which helps detect what is in the water nearby.
Do fish collide?
Fish and birds are able to move in groups, without separating or colliding, due to a newly discovered dynamic: the followers interact with the wake left behind by the leaders.
Which fish can make sharp turns?
Watch the secret to a tuna’s sharp turns. Bluefin tuna can stretch 3 meters, weigh a metric ton, and reach speeds of 60 kilometers per hour.
What is it called when fish swim together?
In biology, any group of fish that stay together for social reasons are shoaling, and if the group is swimming in the same direction in a coordinated manner, they are schooling. In common usage, the terms are sometimes used rather loosely.
What is a flock of fish called?

- Swim actively throughout the entire tank, not just hanging out or laying at the bottom, floating near the top or hiding behind plants and ornaments.
- Eat regularly and swim to the surface quickly at feeding time.
Do fishes sleep?
While fish do not sleep in the same way that land mammals sleep, most fish do rest. Research shows that fish may reduce their activity and metabolism while remaining alert to danger. Some fish float in place, some wedge themselves into a secure spot in the mud or coral, and some even locate a suitable nest.
How do fish see Smell Hear taste and feel?
Fish detect bait by sound and through water movement in the form of vibrations. They hear and feel their way to fishing lures with their ears and lateral lines. When they see the lure, they determine if it looks like something they usually eat. A fish might then smell or taste the lure before attempting to eat it.
How do fish communicate?
It is well known that fish communicate by gesture and motion, as in the highly regimented synchronized swimming of schools of fish. Some species use electrical pulses as signals, and some use bioluminescence, like that of the firefly. Some kinds of fish also release chemicals that can be sensed by smell or taste.
