A photographer has shared entrancing footage of tiny fish moving together in perfect coordination. 

“A hypnotising rhythm of collective consciousness,” says underwater photographer Jono Allen who saw the mesmerising school.

“Looking across the cave as thousands of fish moved in perfect synchronicity, slowly shape shifting together as if making up one single entity was beyond mesmerising,” he says.

“It felt almost like watching a blue flame flicker and dance underwater. I could have stayed with them all day…”

Allen returned to the fish cave day after day to watch the spellbinding school shimmer in the water around him.

But one day he returned to find they had all disappeared. “The day before, thousands of fish were there, yet today maybe 30,” he says.

He was heartbroken by the thought that they might have all been caught by fishermen. But a few days later, he found his fishy friends again – they had moved to another cave around a kilometre away. “The amount of relief and joy I felt was almost embarrassing,” he says.
