Yes, crows do make up a murder I believe!
I was inspired to look further (though I'm running short of time and about to leave for a flight into the worst of the northeast weather, ugh!) and on the Cornell Lab of Ornithology blog they don't mention the algorithms I recalled, but they do say that starlings are most known for this behavior - and it is now called "scale-free correlation". They don't mention fish but I believe as Annie suggested, that schooling fish surely would be considered to exhibit the same thing.
From the blog:  "Murmurations remind us that nature’s beauty can take limitless forms, and can shock and inspire us....  It’s as if seeing that synchrony, that seemingly perfect connection between each starling, also reminds us to value our connection to the world around us, for connection can be truly beautiful."

Have a good day all!..

Maybe not quite on this scale (you do have to wonder how those birds manage not to bump into each other)…

There is a flock of crows that comes to town every winter. Thousands of them. They have favorite roosting places (once of which is a graveyard!). And the sometimes roost across the street from my house in the tall trees on the grounds of our local history museum. They start to gather late afternoon, and circle and settle and take flight and circle some more. This goes on for hours. They finally settle for the night, and the trees are just black with crows.

The name for a group of crows is, I believe, a murder of crows.
