Is all sand fish poop?

No, not all sand is fish poop. Sand is made of various bits of natural material and from many different locations. Most of the sand material starts off in-land, from rocks. These large rocks break down from weathering and eroding over thousands and even millions of years, creating smaller rocks.

Is all sand made by parrotfish?

The famous white-sand beaches of Hawaii, for example, actually come from the poop of parrotfish. The fish bite and scrape algae off of rocks and dead corals with their parrot-like beaks, grind up the inedible calcium-carbonate reef material (made mostly of coral skeletons) in their guts, and then excrete it as sand.
