As you know, flying insects are a favorite food for most fish that live in our home aquariums. Some fish to jump their prey jumps out of the water, and some shoot.
This tactic is peculiar to the well-known fish-sprinkler: they shoot water droplets that knock insects from trees and bushes.
If you say about a similar method of hunting for a beginner aquarist, then he can twist at his temple and say “What stories are you telling me?”. But, nevertheless, such a fish really exists, and we will just talk about it.
Bryzgun fish live near the sea and ocean coasts of Southeast Asia. In the genus, there are five species of fish that inhabit surface waters.
As a rule, these fish are kept in mangroves of the coastal vegetation, in the mouths of large rivers.
Keep this fish easy, if you have created as close as possible to the natural living conditions. Part of the reservoir should be set aside under a piece of land, so that flying insects could land there.
Ideally, this fish should be kept in the paludarium or aquaterrarium. Of course, both species of the reservoir should be well covered, otherwise the potential food for the breeders will fly out, and the fish will not be able to show all their abilities.
Despite the fact that the bryzguny live brackish water, they can easily adapt to life in a freshwater body of water and live in it for five years. But keep in mind that in fresh water fish is subject to various fungal diseases.
To protect your pets, it is better to add sea or table salt in the water.
In feeding, fish-breeders are unpretentious and their diet is not limited to flying bugs. Considering the fact that in nature very often there is not enough food for everyone, and especially familiar food, the fish have to feed on what they have to adapt to in the prevailing conditions.
And now let’s find out how a sprinkler fish hunts insects. The essence of the method of hunting a hydrobiont is that an insect that has sat on a leaf of a plant or snag above the water is shelled by a sprinkler with an aimingly directed stream of water.
The trunk serves as a special groove in the sky, which has the form of a directional chute, along which the fish pushes a stream of water through the tongue.
Due to the fast and well-coordinated action of the gill covers and mouth, under pressure, the fish throws out water at the intended target. With such a zealous approach to hunting, the victim stumbles in the water at the first attempt.
Large individuals are able to shoot far and very accurately. They can easily knock a sitting insect in a half to two meters above the water.
However, it is still not clear how the fish is struggling with the refraction of light during aiming.
At brought young fry-fish with a body length of no more than two centimeters there is a longitudinal line on the body, which consists of a series of brilliant spots. Most likely – this is a kind of identification marks that help fish communicate with each other.
If the aquarium contains a flock of individuals in the amount of 7 to 8 pieces, then all may have similar luminous stripes until the fish mature and reach half of their maximum length.
Sprouts young fish can be kept in a small group, or together with other fish that live in brackish water, such as argus or monodactylus. The main condition is that all fish should be approximately the same size.
