Caring for your Archer Fish
Archer Fish
Toxotidae spp.
Basic Information:
Archer Fish are a fascinating group of brackish to freshwater fish native to Southeast Asia and northern Australia, including regions like Indonesia. They are best known for their unique hunting behavior—shooting jets of water to knock insects off branches above the water’s surface. Adults typically reach 6–12 inches in length depending on species.
They are active, intelligent, and social fish that do best in small groups. Archer Fish are diurnal and require a specialized setup that allows for surface interaction and space above the waterline. Due to their size and specific needs, they are best suited for intermediate to advanced aquarists.
Lifespan:
5–10 years in captivity with proper care.
Sexing:
Sexing is difficult and not typically distinguishable visually.
• Males and females appear very similar.
• Breeding behavior is rarely observed in captivity.
Enclosure:
• Minimum: 55-gallon aquarium for juveniles.
• Adults: 75–125 gallon aquarium or larger depending on species and group size.
Provide a tank with ample horizontal swimming space and a lower water level to allow room above the surface. Include driftwood branches or décor that extend above the waterline to encourage natural hunting behavior.
Substrate:
A standard aquarium substrate works well, such as:
• Sand
• Fine gravel
Substrate choice is less important than maintaining water quality.
Lighting & Temperature:
• Water Temperature: 75–82°F
• Heater: Required to maintain stable temperature
• Lighting: Moderate lighting with a 10–12 hour cycle
Consistent temperature and lighting help support natural behavior.
Water Parameters:
• pH: 7.0–8.0
• Ammonia: 0 ppm
• Nitrite: 0 ppm
• Nitrate: <20 ppm
Many species do best in brackish water as they mature, so gradual salinity adjustments may be required depending on species.
Food:
Archer Fish are carnivorous surface feeders.
• Live or frozen insects (crickets, flies, mealworms)
• High-quality floating pellets
• Occasional frozen foods such as shrimp
Feeding at the surface or above the water helps stimulate natural hunting behavior.
Water:
Maintain clean, stable water conditions with regular water changes (25–50% weekly). Proper filtration is essential due to their size and feeding habits.
Archer Fish are one of the most unique aquarium species due to their incredible ability to shoot water at prey. Their intelligence and interactive feeding behavior make them a standout display fish for hobbyists looking for something different.
