Fanbelly Leatherjacket
Monacanthus chinensis
Fanbelly Leatherjacket (Monacanthus chinensis) is a small, laterally compressed filefish of tropical Indo-Pacific waters, often found around reefs, rubble, and seagrass. It is not a major gamefish, but it can be caught incidentally with light tackle and small baits.
Fantail Darter
Etheostoma flabellare
Fantail Darter is a small North American freshwater darter that lives on clean, flowing streams and rivers with gravel, rubble, or cobble bottoms. Males develop a fan-shaped tail and guard eggs under rocks.
Fathead Minnow
Pimephales promelas
Fathead Minnow (*Pimephales promelas*) is a small North American minnow now widely introduced and often abundant in ponds, ditches, and slow waters. It tolerates low oxygen, warm water, and poor conditions better than many baitfish, which helps it thrive globally in stocked and disturbed habitats.
Finescale Triggerfish
Balistes polylepis
The finescale triggerfish (Balistes polylepis) is a coastal reef-associated triggerfish of the eastern Pacific. It is a powerful, armored predator that feeds on hard-shelled invertebrates and is more often encountered by divers than targeted anglers.
Fire Dartfish
Nemateleotris magnifica
Fire Dartfish (Nemateleotris magnifica) is a small Indo-Pacific reef fish known for hovering above rubble and bolt-hole retreats. It is primarily an aquarium species and is not a standard food or game fish.
Five-spotted Wrasse
Symphodus roissali
Five-spotted Wrasse (Symphodus roissali) is a small eastern Atlantic–Mediterranean wrasse that lives in shallow coastal reefs and seagrass. Males can show vivid breeding colors and spotted patterning; it is generally more of a view species than a target fish.
Fiveline Cardinalfish
Cheilodipterus quinquelineatus
The Fiveline Cardinalfish is a small nocturnal reef fish from the Indo-Pacific, commonly sheltering in caves and coral branches by day and foraging at night. It is not a major angling target and is best treated as a reef-associated species of interest to divers and aquarium observers.
Flagtail Grouper
Cephalopholis urodeta
Flagtail Grouper (Cephalopholis urodeta) is a small reef grouper of the Indo-Pacific, usually found on coral-rich drop-offs and lagoon reefs. It is an ambush predator that feeds mainly on small fishes and crustaceans and is occasionally taken by line anglers.
Flagtail Triggerfish
Sufflamen chrysopterum
Flagtail Triggerfish is a reef-associated triggerfish of the Indo-Pacific that uses rubble slopes and outer reef drop-offs, where it grazes hard-shelled prey. It is not a major game fish; anglers target it only incidentally or for reef fishing interest.
Flathead Catfish
Pylodictis olivaris
Flathead Catfish are large, nocturnal ambush predators of big rivers, reservoirs, and deep holes in North American freshwater systems. They are prized by anglers for size and table quality, but they readily eat live fish and other sizable prey.
Flathead Catfish
Pylodictis olivaris
Flathead Catfish (Pylodictis olivaris) is a large North American catfish that lives in big rivers, reservoirs, and deep holes with cover. It is a nocturnal ambush predator that mainly eats live fish, making it a prized big-fish target.
Flier
Centrarchus macropterus
The flier is a small North American sunfish with a very deep body and a dark spot at the rear of the dorsal fin. It is a warmwater, freshwater species common in vegetated ponds, swamps, and slow streams, and is a minor angling fish rather than a major game species.
