Freshwater Archerfish Identification Guide

Key identification features

• Large, deep, laterally compressed silver body, growing bigger overall than most related archerfish
• Five to seven irregular, often broken or blotchy dark markings along the flanks, rather than clean stripes
• Sharply upturned, pointed mouth used to spit jets of water at prey above the surface
• Dorsal fin positioned well back on the body, aligned with the anal fin
• Large, forward-facing eyes adapted for judging distance and refraction when aiming above water
• Can reach up to 40 cm, notably larger than the banded archerfish

Common look-alikes

• Banded archerfish: smaller, with four to six clean, evenly spaced vertical bands rather than irregular blotches
• Spotted scat: similarly deep-bodied and silvery but patterned with scattered round spots and lacking the archerfish's upturned mouth
• Other archerfish species: best separated by counting and examining the regularity of the body markings

Where you'll see one

Freshwater archerfish range across rivers, floodplain lakes, and brackish estuaries from South and Southeast Asia to northern Australia, tolerating everything from fully fresh to brackish water. They cruise just beneath the surface near overhanging vegetation and mangroves, scanning for insects and small prey on leaves or branches before firing a precise stream of water to dislodge them.
