Characidium vidali
Characidium vidali is a tiny characin native to clear freshwater streams in South America. Reaching only about 6.4 cm, it is popular among micro‑catch enthusiasts rather than as a food fish. Anglers target it for its delicate size and the challenge of presenting an appropriately small lure.
