Description
The Rio Verde Astyanax is a hardy and adaptable freshwater fish, typically displaying a silvery body with a prominent lateral stripe and a caudal spot. While famous for its blind cave-dwelling variant, the sighted form is an active swimmer found in rivers and streams. They are generally peaceful but thrive best in schools to prevent fin-nipping.
