Banded archerfish have very accurate aim and have a shooting range of about 60 inches!
- Feeds at the surface during the daytime on floating debris which includes insects and plant material.
- Renowned for its ability to “shoot down” insect prey by expelling beads of water from its mouth with considerable force.
- Shooting range is about 60 inches (150 cm).
- Uses its jaw muscles to pump water through a tube formed by its tongue and a unique channel in the roof of its mouth. The stream of water droplets knocks its prey into the water where it is easily devoured.
- Can compensate for visual refraction while looking from beneath the water surface to a target in the air above.
- Very accurate aim due to special adaptations in the eye which give it an unusually large area on the retina in which it can focus an image and still have the image be clear.
- Occurs from India eastward to the Philippines and south to Indonesia, the Solomon Islands, Papua New Guinea and Northern Australia.
- Found primarily in brackish mangrove estuaries, but also penetrates adjacent rivers and small streams.
- Also reported to occur near overhanging vegetation on reefs.
- “Least Concern” on the IUCN Red List.
- Popular among home aquarists.
- In some parts of its range, it is harvested and sold fresh in the marketplace.
