Green Sunfish (Lepomis cyanellus) lives in freshwater lakes across North America. It feeds on insects and crustaceans. Its conservation status is Least Concern.
Fascinating facts about the Green Sunfish
- Green sunfish are notorious invaders that actively chase other sunfish away from shared submerged-vegetation habitats, using interference competition to dominate the niche. Their success is boosted by a relatively large mouth that lets them consume a wide range of prey and by an exceptionally high fecundity that floods waters with thousands of eggs. They also tolerate heavily polluted, sediment-laden waters, allowing them to thrive where other species struggle.
- During the summer spawning season a female green sunfish deposits between 2,000 and 26,000 eggs in a nest built by a male in shallow water near rocks or logs. After the female departs, the male assumes sole responsibility, guarding the clutch for three to five days while fanning the eggs with his fins to keep them clean and oxygenated. When the fry hatch they linger near the nest for a few days before venturing out to feed on their own.
- Green sunfish typically measure 3-6 inches (7.6-15.2 cm) in length, with most individuals falling between 3 and 7 inches and weighing under a pound. Exceptional specimens, however, can reach a maximum recorded length of about 30 cm (12 in) and a weight of up to 960 g (2.12 lb). This size range means that while most anglers encounter modest-sized fish, the species is capable of growing far larger under favourable conditions.
- The all-tackle IGFA world record for green sunfish is a 0.96 kg specimen taken from Stockton Lake, Missouri, in 1971. This record weight is close to the species' maximum recorded mass of 960 g, showing that individuals can grow far larger than the usual sub-pound size most anglers see. Typical green sunfish measure 3-7 in and weigh less than a pound, but under favourable conditions they can reach up to 30 cm and approach the record weight.
- Females sometimes deposit eggs in the nests of other sunfish species, producing hybrid offspring that blur species boundaries. This occurs because green sunfish nest close to both conspecifics and other sunfish, leading to occasional cross-species spawning. The resulting hybrids often display a mix of parental traits, which makes reliable identification of pure green sunfish difficult.

About the Green Sunfish
In the warm, languid waters of North America's lakes and rivers, the Green Sunfish glides with an effortless elegance, its iridescent scales shimmering like polished jade as it navigates the submerged world with a quiet confidence. With a subtle flick of its tail, it darts between the aquatic vegetation, its large mouth and sharp teeth ever-ready to snatch unsuspecting insects and crustaceans from the shadows. As it moves, the sunlight dancing across the ripples of the water seems to accentuate the sunfish's own radiant hue, as if the very essence of the natural world has been distilled into this one, unassuming creature.
