Spotted Gar (8–10 cm) – an ancient predator with a sleek, spotted body and elongated snout. Perfect for monster fish keepers with large tanks or ponds.

The Spotted Gar (Lepisosteus oculatus) is a striking freshwater predator with a history stretching back millions of years, making it a true living fossil. Recognized for its elongated, torpedo-shaped body, crocodile-like snout, and bold dark spots, the Spotted Gar is a favorite among monster fish enthusiasts for its prehistoric appearance and calm demeanor.
