Species Overview
Guppy
The guppy is one of the most widely distributed tropical fish, found in freshwater habitats across the Americas. Males display vivid colors and elaborate tail patterns to attract females. They are live-bearers, giving birth to free-swimming fry.
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.
