Predators have devised various countermeasures to undermine the defensive shoaling and schooling manoeuvres of forage fish. The sailfish raises its sail to make it appear much larger so it can herd a school of fish or squid. Swordfish charge at high speed through forage fish schools, slashing with their swords to kill or stun prey. They then ...
A bait ball is a last-ditch defensive measure adopted by fish schools when they are overwhelmed and more effective defensive strategies have broken down. Schooling fish are easier to attack once they abandon their free streaming behaviour and form into a tight bait ball.
Shoaling behavior improves foraging success, because the demand for anti-predatory activities per individual is reduced and because more individuals scanning for food leads to quicker detection. In general, a larger shoal of fish locates food faster, which was confirmed to be true in common minnows.

Although it is a small fish, the White Cloud Mountain minnow is sometimes used as a pond fish, especially in ponds intended for frogs to breed. Adult White Cloud Mountain minnows will sometimes eat frog eggs as the tadpoles begin to move about or wait for them to hatch. Once tadpoles are a couple of days old they are out of danger.

Shoaling – describes the behaviour of fish which aggregate together, including mixed species groups. Fish derive many benefits from shoaling behaviour including defence against predators through better predator detection and by diluting the chance of capture, enhanced foraging success, and higher success in finding a mate.
They are a somewhat aggressive fish, and may bully other fish in community tanks. Giant danios appreciate water movement to simulate the motion of the rivers and fast-moving streams of their origins, and prefer to school. Giant danios are also used as dither fish in South and Central American cichlid aquariums. The larger cichlids chase and ...
