The freshwater angelfish is a majestic cichlid with a laterally compressed body and long, flowing dorsal and anal fins. Native to the Amazon basin, it has been selectively bred into numerous color varieties including marble, koi, and platinum.
Northern Pike
The northern pike is an apex predator of freshwater lakes and rivers across the Northern Hemisphere. With its elongated body, duck-bill snout, and razor-sharp teeth, it ambushes prey with explosive bursts of speed.
