Popularly called Killis they have divided into at least 10 families and at least 65 genres, many of them with more than 100 species.

We have a very large family, globally distributed and with the ability to adapt to the most diverse climates.

A few species have adapted to living in the sea and in some large lakes with high concentrations of dissolved salts.

Adapting to such diverse biotopes allowed them to overcome one of the unavoidable conditions for other fish.

That is why this species manages to ensure the survival of the species despite the absence of water in its environment.

The members of this family are the only ones that can produce eggs capable of withstanding a drought of up to two years or more, depending on the species.

This phenomenon is what allowed the worldwide dissemination of the killifish.

The killifish are fish that have a greater color within the species of freshwater, and some of them rival in beauty with the fish of the coral reefs.

Characteristics: 

The scientific name of the killifish is Aphyosemion Australe. The killifish is the most interesting and curious species. They are exclusive fish, hard to find and with a world of true fans about them.

There is a great variety of species and diversities that inhabit all over the world except in Oceania, North Asia, and Northwest North America.

Although they inhabit regions with an intertropical environment you can also find species in cold and moderate climates.

They live in unstable natural environments, in aquatic environments such as ponds, streams, reservoirs and other places of that nature.

The majority of the body of the killifish has a cylindrical shape. The size of the fish is between 3 and 7 centimeters, although there are also smaller and larger species.

Everyone has a small mouth and tiny teeth in the jaws and pharynx. The head is usually slightly flat in the upper area.

The difference between males and females is appreciable, especially in size and color. The males are larger than the females and look justify and strong colors.

While the female is smaller, look more pale and muted colors. They usually live in small populations composed of several females and a dominant male that does not allow the existence of other males that can be seen as competition.

The average life of this species is between 1 to 3 years. Even so, this species is very complicated to obtain and in some places, it is beginning to be considered in danger of extinction.

Those breeders who want to maintain this species are essential to take care of it properly.

Feeding: 

These fish are insectivores. They must have a very varied diet, they like to feed a couple of times a day with live food.

The feeding can be larvae, insects, mosquitoes, fruit flies, micro-worms, earthworms, etc.

But even if it is not the favorite, the breeder should also give them some porridge with vegetables so that they have a varied diet. You may also like to read goldfish

Reproduction:

If someone wants to raise these fish and use them for their reproduction, they should give up having only one of these fish in an aquarium coexisting with other fish.

This is because these fish, in addition to being aggressive, should have their space to carry out the reproduction correctly.

An acceptable alternative is to select an aquarium in which they can breed and reproduce themselves.

While knowing that they are going to try to promote the precise reproduction and breeding of these fish, collecting their eggs and reproducing them later.

It should also be noted that the power of an impeccable reproduction of the killifish is difficult since most of its species show disadvantages of sterility.

In the same way, they have problems with the number between males and females and of particular obligations with water.

Behavior: 

Most of the killifish species are annual, that is, they usually live only one year. For example the subspecies Aphyosemion lives for a very short time.

Because it lives in a dry season and it is impossible for it to survive longer. Many of these fish are found in the Gulf of Guinea.

And others have moved further into the territory so the water already has very low amounts of salt. You may also like to read Rainbowfish

These fish will also vary their behavior in reproduction, the search for food and in general, to ensure the survival of their species.

It is a species that is territorial so they protect their territory. Defending and in general acting always guided by the instinct of survival more primary.

Becoming more violent with it or with other species. In addition, it should be noted that the behaviors will also vary according to whether they are annual killifish, semi-annual killifish or non-annual killifish.

Aquarius: 

The killifish do not need aquariums of large dimensions, a volume of 10 or 15 liters is enough for a couple or a trio. In general, the aquarium should be longer and wider than high, and preferably glass.

It is advisable that it be provided with a lid, especially in the case of jumping species.

Some trunks and aquatic plants can be included as a refuge, bearing in mind that they must be resistant. AND

The moss of Java, the Microsorium Pteropus or the anubias are the most recommended plants.

The aquarium should be equipped with a fluorescent lamp and a box filter. In addition, the temperature of the aquarium should be maintained between 18 and 26 degrees Celsius.

And the Ph should be rather neutral, and be between 5.5 and 7. It is important that the water does not contain chlorine.

To eliminate it, the breeder can leave the water resting for at least 4 days. In one or more containers until the chlorine evaporates.

For good maintenance of killifish it is necessary to change the water habitually to reduce waste and bacteria.

A change can be made weekly, emptying at least 50% of the aquarium water with a siphon and filling it again with clean water without chlorine.
