I'm not a fish person so to me, this is a little gross, but yeah, also amazing -- thousands of tiny catfish who just nibbled their way out of their sac and now have free run of the lake.

Somewhere nearby is the papa catfish, who's the one who dug the nest, lured the female, then fertilized her eggs. AND, after all that, hung around as the eggs hatched, fanning them with his fins and tail to keep the sediment away and the oxygen flowing.

Who knew?
