About the Banded Archerfish
Banded archerfish are large surface-oriented fish famous for shooting jets of water at insects above them. Their feeding trick is impressive, but their adult size and social needs make them a specialist commitment.
They need a substantial group and a very large aquarium. A juvenile should not be purchased with only a vague plan to upgrade later.
Health risks to know about
Important concerns include ammonia or nitrite poisoning, salinity shock, jumping injuries, collisions when startled, poor nutrition, parasites and stress from a group that is too small.
Rapid breathing, nose damage, clamped fins, repeated frantic dashing, weight loss or leaving the group needs prompt investigation.
Tank, water and equipment
Plan for a very large, mature brackish aquarium with a secure lid, strong filtration, high oxygen, long open swimming room and calm overhead space.
Use marine salt mix and a calibrated refractometer. Archerfish generally use low-to-medium brackish conditions, but exact salinity should match the species and source.
Food and feeding
Offer complete floating carnivore foods with varied frozen aquatic foods. Safe cultured insects can provide enrichment when sourced and offered appropriately.
Do not rely on wild-caught insects that may carry pesticides, and remove anything uneaten.
Behaviour, tank mates and enrichment
Surface cruising, schooling and aiming at food above the water are normal. Keep a substantial same-species group rather than a lone novelty fish.
Choose only robust tank mates that share the same salinity and cannot be swallowed.
When to contact an aquatic veterinarian
Get help for gasping, collapse, severe wounds, major swelling, inability to stay upright, rapid unexplained deaths or a problem that continues after water parameters are corrected.
Test ammonia, nitrite, nitrate, pH, temperature and salinity whenever behaviour changes. Water quality is part of the medical history, so record results before contacting an aquatic veterinarian.
