Green Sunfish

The green sunfish (Lepomis cyanellus) is a small, aggressive freshwater fish native to North America. This fish has a deep, laterally compressed body with a greenish hue, yellow or blue speckles, and distinct black ear flaps. It grows between 4 and 10 inches in length and weighs up to a pound. Its mouth is larger than most other sunfish, allowing it to consume a variety of prey. Green sunfish are opportunistic feeders, consuming insects, crustaceans, small fish, and plant matter. This species is highly adaptable and can thrive in a wide range of aquatic environments, including ponds, lakes, rivers, and even stagnant or low-oxygen waters. Their aggressive nature makes them dominant competitors in many ecosystems. Green sunfish spawn in shallow nests built by males in warm months. Males aggressively defend their nests and newly hatched fry. Due to their adaptability and tolerance for poor water conditions, they have spread beyond their native range, sometimes becoming invasive and outcompeting native fish. Although considered a nuisance in some areas, green sunfish are popular among anglers due to their strong fight when hooked. They are also occasionally kept in aquariums due to their hardiness and interesting behavior.

Fun Fact: Green sunfish may stay in the same area for several years, defending their homes from other fishes.
