The giant snakehead (Channa micropeltes) is a predatory freshwater fish native to Southeast Asia. This species is characterized by its elongated body and sharp teeth. Known for being aggressive and highly territorial, giant snakeheads thrive in various freshwater habitats, including rivers, lakes, and swamps. Cool fact, they can survive in low-oxygen environments and have the ability to breathe air, allowing them to move short distances on land.

The Oriental Butterflyfish (Chaetodon auripes) is a striking species found in the western Pacific’s rocky reefs and coastal waters, particularly around Japan, Korea, and Taiwan. They are known for their vibrant yellow body and bold black bands. This fish is often seen in pairs, a behavior typical of many butterflyfish species. Primarily feeding on coral polyps and small invertebrates, the oriental butterflyfish plays a vital role in maintaining the health of coral reef ecosystems.

The European bitterling (Rhodeus amarus) is a small freshwater fish found in rivers and lakes throughout Europe. Like its close relative, the Amur bitterling (Rhodeus sericeus), it has a unique reproductive strategy that involves freshwater mussels, using them to protect its eggs. Although both species share this fascinating symbiotic relationship, the European bitterling is identifiable by its more muted coloration and its wider distribution across Europe, ranging from the Rhine River to the Black Sea.

The bluegill (Lepomis macrochirus) is a popular freshwater fish native to North America. It is commonly found in lakes, ponds, and slow-moving rivers. The bluegill is recognizable by its deep, compressed body and a distinctive dark spot at the base of its dorsal fin; this species also displays iridescent blue and green hues, especially around its gills. Bluegills play an important role in aquatic ecosystems, as they feed on insects, small fish, and crustaceans.
