Archerfish Hunts and Kills it Land-based Prey with Deadly Aim
The Archerfish has mystified people as to how it catches its prey for years. West Australian Scientists have finally unlocked the secret of how it kills and hunts its land-based prey. This cunning fish can torpedo any fast moving insect from their position of a leafy perch by spitting a jet of water with incredible accuracy.
Not like Other varieties of Fish
Archerfish aptly named because of its capability of shooting a stream of water at it unwary insect sitting on a branch above water level. These fish are native to Northern Australia, Sri Lank and New Guinea. They grow between 20 to 40cms in length and Its body color is normally silver with black dots along its back.
They feed on insects and debris in the water and catching the insects through its unusual killer like spout of water, which knocks the insect into the water where the archerfish is ready and waiting.
Biologists have revealed that this fish can tune its eyes in three different directions. Not only focusing on land above water level it can focus on predators under the water and sees it all in color. This revelation may be the reason behind how this fish can adapt to any environment on this earth giving it a better advantage over all the other types of fish.
These unusual fish have found a way to tune the rods and cones across their retina to suit a shadowlike variance which enables it to see in and out of the water. To do this it angles it jaw to shoot the water in it mouth at the insects. The archerfish eats the insect or grasshopper before it has time to escape.
It is believed that this study could lead to different ideas in designing sensors for underwater navigation vehicles.
Can archerfish be kept in an aquarium?
You can keep archerfish in an aquarium, although it would need to be a large one for the smaller archer fish, and they need clean brackish water. These type of fish are not for the beginner aquarium owner.
Start young archerfish on two teaspoons of salt per gallon of water and reduce this as they grow.
Can you put other fish in with archer fish?
You can although you would need the other fish to be much larger than the archerfish so they cannot eat them. Archerfish will also eat worms.
As I said earlier these types of fish are for the experts to have in aquariums as there is a lot to learn about keeping brackish water fish.
