Archer Fish (3 Inches) | Single

A 3-inch Archerfish is a sub-adult, quickly transitioning from juvenile to adult size. At this stage, it needs a larger aquarium and may soon require brackish water for long-term health. Known for their remarkable hunting behavior, Archerfish shoot jets of water to knock insects into the tank — a fascinating display in home aquariums.
