Description
The Ouachita Studfish is a vibrant, elongated killifish native to the clear, flowing waters of the Ouachita Mountains. Males exhibit striking orange and blue horizontal stripes and spots, particularly during breeding, with a distinctive black margin on the caudal fin. They are active, bottom-to-mid dwelling fish that thrive in well-oxygenated tanks with ample vegetation and hiding spots.
