The Archerfishes are interesting, but primarily brackish water species that require a special setup and diet to thrive and are thus not suited for the average tropical community aquarium, where they tend to do poorly and waste away.
Other common name(s):
Habitat: Mangrove swamps with brackish water and overhanging vegetation. This species is justifiably respected for its ability to shoot beads of water up to 1.5 meters (60 in) to hit insects and drop them into the water where it grabs them immediately. They will also leap out of the water to grab prey from overhanging branches. An aquarium with a tall canopy is required.
Maximum length: 30 cm (12 in)
Minimum aquarium size: 285 L (75 gal)
Water: Brackish 25 °C (77 °F) - 30 °C (86 °F)
General swimming level: Top.
Omnivore. Meaty foods, including live feeder crickets, and tender floating aquatic plants.
May do best when kept in small groups of 3-5. Many pursue and eat smaller fishes.
Not recommended for the average home aquarium.
Not bred in captivity. There are reports that adults may move out into full saltwater and spawn in reef areas.
