Key identification features
- Very tall, strongly compressed, near-circular diamond-shaped body
- Bright silver coloring with a noticeable golden-yellow wash on the fins and body edges
- Three distinct dark vertical bars crossing the head and forebody, more numerous than in close relatives
- Tall, sweeping dorsal and anal fins that emphasize the rounded body outline
- Small mouth positioned at the tip of a blunt snout
- Typically reaches 20-27 cm, larger overall than the related mono
Common look-alikes
- Mono (silver moony): shares the diamond silhouette but carries only two dark bars and less yellow fin coloration
- Silver mono: essentially identical to the mono in pattern, again separated from fingerfish by having two bars instead of three
- Freshwater angelfish: also tall-bodied and banded, but has elongated trailing fin filaments and lives strictly in fresh water, unlike the brackish-loving fingerfish
Where you'll see one
Fingerfish are native to West African coastal waters, inhabiting estuaries, lagoons, and mangrove-lined river mouths where salinity fluctuates with the tides. They school in open water over sand or mud, often near river mouths and harbor areas, moving between brackish and nearly fresh conditions depending on the season and their stage of growth.
Frequently asked questions
How do I tell a fingerfish from a mono?
