Freshwater Archerfish

The Freshwater Archerfish (Toxotes chatareus), also known as the Common Archerfish, is a member of the family Toxotidae and the largest species in the genus, reaching lengths well beyond its close relatives. It is native to fresh and brackish waters of Southeast Asia and northern Australia, and it tolerates fully freshwater conditions better than most other archerfish, allowing it to range further upstream in rivers and lakes. Like other archerfish, it is celebrated for its ability to spit accurately aimed jets of water to capture insect prey above the surface. The species is common throughout its range and is popular in the aquarium trade.

Freshwater Archerfish have a deep, laterally compressed body reaching 25-40 cm, notably larger than most other archerfish species, with a silver base color marked by scattered dark spots and irregular blotches rather than bold, continuous bars.

Key features:

• Flat dorsal profile leading to a pointed, upturned mouth adapted for spitting
• Large, forward-set eyes for judging prey distance above water
• Dorsal and anal fins positioned toward the rear of the body, often yellow-tinged
• Slightly forked caudal fin
• Overall larger, more robust build than the Banded Archerfish

The scattered-spot pattern, versus bold vertical bars, and notably larger adult size distinguish the Freshwater Archerfish from the similarly ranged Banded Archerfish (T. jaculatrix).

Freshwater Archerfish are native to Southeast Asia, including Indonesia, Malaysia, and the Philippines, as well as northern Australia and New Guinea. They occupy a broader range of salinities than most archerfish, found in coastal brackish estuaries as well as freshwater rivers, lakes, and swamps well inland. They favor still or slow-moving water with overhanging vegetation and structure, such as riverbanks and flooded forest margins, which support their insect-hunting behavior, and they readily colonize man-made reservoirs and irrigation canals within their range.

Freshwater Archerfish hunt using the same specialized water-spitting technique as other archerfish, positioning themselves near the surface and expelling precise jets of water to dislodge insects and other prey from overhanging leaves and branches before quickly seizing the fallen prey. They frequently hunt in loose groups, sometimes competing for the same target, and can also leap from the water to grab low-hanging prey directly. In addition to insects, they take small crustaceans and fish when surface prey is limited. Freshwater Archerfish spawn in open water, releasing pelagic eggs, and their tolerance for a wide salinity range allows populations to move between freshwater and brackish habitats over their lifetimes.
