Key identification features
- Elongated, moderately compressed silvery body
- Three to four bold, curving black stripes running diagonally along the sides
- Distinct dark blotch, the "target" spot, at the base of the tail
- Spiny, well-developed first dorsal fin
- Grows to about 12 inches (30 cm)
Common look-alikes
- Crescent perch (Terapon theraps) shows straighter, more parallel stripes that do not converge toward a caudal spot the way the targetfish's do.
- Small-scaled terapon (Terapon puta) has fewer, fainter stripes and stays noticeably smaller at maturity.
- Striped damselfish look superficially similar but lack both the spiny dorsal fin and the dark target spot at the tail base.
Where you'll see one
Targetfish are common in coastal waters, estuaries, tidal creeks, and river mouths across the Indo-Pacific, typically cruising over sandy or muddy bottoms in small groups. They tolerate a wide range of salinities, moving freely between full seawater and brackish river mouths, and are frequently encountered close to shore in harbors, lagoons, and around jetties.
Frequently asked questions
How do I tell a targetfish from a crescent perch?
Check the stripe pattern: targetfish have curving stripes that converge near a dark 'target' spot at the tail base, while crescent perch stripes run straighter and more parallel.
What single mark gives the targetfish its name?
A bold, round dark blotch at the base of the tail resembling a bullseye is the field mark that gives the targetfish its common name.
