Archerfish (Toxotes)
Brackish fish that spews jets of water to knock down insects from branches above the surface. One of the most fascinating behaviours of the aquatic world.
Detailed explanation
The archerfish (Toxotes jaculatrix) is famous for its ability to spit precise jets of water to kill insects and terrestrial prey.
In the aquarium this ability is observed by feeding them with crickets or flies positioned on a branch above the surface. The show is amazing.
They are brackish fish (SG 1.005-1.015) that grow to 20-25 cm. They require large aquariums with air space above the water.
A semi-open aquarium with branches and emerged plants extending above the surface recreates their natural habitat.
