Fish from freshwater live in waters with saltiness under 0.05 %. Although freshwater form only around 0.3 % of all water on the world, there populate around 15,000 different kinds of freshwater fishes. Those fishes range by size: of kinds long only some millimeters until such that reaches several meters.
For example, the pencilfish grow until a half inch, like the Danionella Dracula, that measures bare 0.5 inches. Even more tiny is the Paedocypris progenetica, the most little animal and fish that we know.
