It Doesn't Rain Fish, It Floods ThemA century-old miracle gets a geological explanation.

It really happened

Every year in Honduras, a storm leaves hundreds of fish stranded in the fields. This phenomenon, known as the 'Lluvia de Peces,' has long been considered a miracle. The truth is less magical, but just as fascinating. The fish aren't falling from the sky. They are blind, freshwater species forced up from subterranean streams when heavy rains flood their underground homes. The storm simply reveals what was hidden beneath the surface all along.
