Killifish overview
Cyprinodontiformes, popularly known as killifish, is a family of fish that settle on 1250 species; These species are classified into ten(10) different groups.
The Killifish family is a diverse group of fish. They have adapted to live in a wide range of different habitats and it is found in almost every continent of the world except Australia and Antarctica.
Killifish are found mainly in shallow mini-tropical and tropical waters.
They live in both still and running water, they are mostly freshwater fish; However, there are a few species that are pure and salty.

In their natural environment, some killifish (annual killifish) have a lifespan that lasts only a few months.
Although the phrase “Kylie” seems dangerous, this is why Kyliefish did not get its name. “Kili” originally originated from the Dutch world, meaning canal digging.
Huge numbers of killifish reach one or two inches long, larger species up to six inches.
Killifish Lifespan
three months – five years (3months – 5 years) (depending on the species)
Killifish Basic Breeding
To try to breed this killifish, it is a difficult but achievable project. For top broodstocks, a 1/2 inch layer of pre-boiled peat sediment at the bottom of the breeding pond makes the water acidic and provides a darker surface preferred by these fish. The pit should be boiled for five minutes, then all the excess acidity should come out of the pit.
For the bottom broodstock, the pit should be about one inch thick for sufficient depth of spouting. Keep in mind that these species must have the ability to bury their eggs in order to survive during the impending drought.
It is better to have one male with three females in the spanning because the males are rigid conductors. Males are usually easily distinguished because many species have lyre-shaped tails and are much more colourful than females.

It takes about three weeks for the eggs to hatch from the hangar, while the spanner eggs at the bottom should be kept in a moist peat sash for about three months (depending on the species) before the water returns to the tank.
By buying eggs from breeders online, it is possible to get a miraculous experience of the Killifish life cycle. These eggs appear in moist peat sash and have already aged properly. Add the appropriate water as you instructed and within a few hours, you are done frying. This is a cheaper and easier way to acquire a collection of dead fish than buying adult fish and since they have such a short lifespan, you can experience them for a much longer period of time. .
Chocolate Lyretail (AphyosemionAustrail)
This popular killifish comes from West Africa where it lives in small streams and ponds of rainfall. It grows 2 1/2 inches. They are very easy to have sex, featured lyre-shaped tailed males. They need soft, acidic water and this is egg suspension. They will get a few eggs a day from the strands of nylon wool mop suspended from the cork stopper.
Gardneri (AphyosemionGardneri)
It also comes from West Africa and grows to 3/4 inch. It comes in the form of two colours: yellow where the male ankle, anus and surface fins are yellow and blue form where yellow is replaced by a pale blue. The woman is very similar to all the Ephesian girls. This is another hanger with the egg which takes 21 to 30 days depending on the temperature.
Limetus (Apolloiaslinus)
This strong and sturdy “Panchax” comes from India, where it grows up to 4/2 inch. It can live well in community aquariums but can eat small fish and gupi bhaji. The male is brighter in colour than the female, which is longer. This is a common hanger and it takes about three weeks for the eggs to be pruned depending on the temperature. He will eat dry food.

Bivittatum (AphyosemionBivittatum)
This killifish also comes from West Africa and grows to 2/2 inch. The fish has poorly coloured and round fins. This fish usually lays eggs in the roots of floating plants in the egg carrier (surface spanner) but adopts floating mop of nylon fur in the aquarium. The eggs hatch in 14 to 21 days. Like all “kilais” (given tooth carp), it is not a community reservoir fish.
Blue Gularis (AphyosemionSjoestedti)
This fish also comes from West Africa. It is a fish larger than most s Eggs should only be spread for 16 weeks in a damp batter.
Dwarf Argentine Pearl Fish (CynolebiasNigripinnis)
This type of killifish is egg-burying (bottom-spawning) killifish originated from the Argentine.
It grows up to one to one and a half inches (1 1/2 inches). ponds that dry up in the dry season is where this type of killifish live, and this killifish like buries their eggs in the mud at the bottom of the pond. In the aquarium for proper healthy and good care, killifish needs 1 1/2 layers of peat, and a temperature of about 70 F,
and also needed soft water. This type of killifish eggs needs incubating in just-moist peat for not more than 16 weeks.
American Flagfish (JordanellaFloridae)
This fish comes from Florida and Central America where it lives in ponds and wetlands. The male reaches about 3 inches in length and the female is somewhat shorter. It is sometimes an invasive fish. Females are usually more fluffy than males and are more fun than coloured males with surface ulcers. The male colour resembles the American flag in a very good example of this fish, hence the common name. The bottom of the fish tank will lay eggs in bunches of peat fibre. The eggs hatch in five to ten days.
Annual Killifish
In the natural environment, annual killifish keep his life permanently in stagnant water that dries up every year and killifish.
As a result, these fish adapt to increasing and reaching sexual maturity very quickly, usually within a few weeks. They lay their eggs in peat algae and when the water comes back they stop.
In aquarium environments, they will need sand from a small breeding pond or a peat algae substrate where they can bury their eggs.
READ ALSO: What Do Jellyfish Eat
Water and parents should be removed after laying eggs and keep the substrate warm and moist for about 3 months.
After this period, water can be added again and the fry should be hatched.
Annual killifish in aquariums are up to 2 years old.
Non-annual Killifish
The natural habitat of non-annual killifish does not dry out. Boil the eggs in water for a very short time.
They will need many more empty tanks. Some breeders prefer to include plants with slender leaves; However, removing eggs from plants can be difficult.
If you choose to include plants, you may want parents to remove them as soon as possible after they have laid their eggs to prevent them from eating.
Non-annual keys have a longer lifespan and grow much slower than annual keys.

Clown Killifish Complete Guide
This little kelpfish boasts incredible colour, especially among men and it’s great for nano or implanted aquariums!
The Clown Killifish (Epileptis annulatus) is a very colourful and peaceful fish, the small size of which makes it perfect for nano or implanted aquariums. Localized in West Africa due to land waterlogging and slow-flowing currents, this fish is suitable for aquariums with very low water flow or with a proper maintenance program, no water flow is excellent
Clown killifish occupy almost exclusively the upper level of the water column. It is not afraid to jump, so it should be kept in an aquarium with an id/hood / alert or at least a significantly reduced water level. It won’t eat or bother plants and it will appreciate the cover, especially with floating plants.
The Killifish Clown may be compatible with other calm species of fish and invertebrates that thrive in low water currents, but only if these species do not compete with the Killifish Clown for food. Also, other species of fish can eat most of the fried killifish clowns during seed germination, so other species of tank mates are not recommended if breeding is desired. Although many killifish are paired, the killifish clown is seen successfully and shows the best colour images in groups.
Clown killifish are not as versatile as other aquarium fish in terms of eating habits. It is a micro predator and it feeds on water. He may ignore floating dry foods, but these foods are not the ideal food despite being adopted by the Killifish Clown. Appropriately sized frozen foods such as Tubifex, Daphnia, and Artemia will generally be accepted, and blood worms may also be used if cut to a manageable size. Live food is the absolute best food for the Killifish clown and he will gladly take the fruit flies and take live samples of the mentioned frozen food.

Killifish Tank Setup
A 20-gallon tank is suitable for regular killifish; If you go for a larger species, you can adjust the size of your tank accordingly.
Most kilos are long, shallow tanks with very little to no water movement. Your aquarium should have lots of living plants, mostly floating plants.
Suitable plants include cryptocurrencies. This is because they work well with low light levels.
The tank may be empty in the ground but most people prefer to cover it with dark gravel. If you choose to use pebbles, you should choose one that will not harden the water.

If you are wondering what things you should not put in your tank, you can read this article.
Do not use pebbles if you wish to keep the breeders below, but you can use peat (unless it contains fertilizer or additives).
You should also provide a hiding place for your keys; It can be on floating plants, rocks or wooden roots.
Killifish Tank Conditions
The water condition of your aquarium depends entirely on the species of killifish that will live in it.
The water temperature is 72-75 ° F for most of the killifish, you can use a regular aquarium heater if you only have one tank, however, more serious killifish keepers who have room can heat the whole house instead of filling the tank.
The pH balance in each killifish tank is different because each killifish has a different choice. For example, some acids come from soft water and others live in hard alkaline water.
Water hardness of 120–160 ppm is appropriate for most kilos, water hardness is not so much a critique for achieving a good pH balance, although some species require soft water (better for breeding) or hard (for example, nootobranchias).
Light again depends on the species; Most kills are used for protection from direct sunlight and therefore prefer low light tanks.
Most killifish require little or no water movement
As for filtration, if you choose a smaller tank, you’ll probably need to use a filter (unless you’re ready to make small, frequent water changes).

Smaller tanks are easier to pollute than larger ones because waste accumulates faster.
A filter will break down toxins and the most common type to use in a small tank is a filter box with a filter sponge or filter wool.
If you have a large aquarium, you can use the bottom of the gravel filters
Water Requirements for Killifish
Although much killifish originate from fresh, acidic water, captive-bred strains that have adapted to local water conditions are increasingly common. Prior to purchase, it is advisable to carefully research the killifish to find out under what water conditions the fish was raised. The preferred water conditions vary by species, but most kills work well at pH 6.0 to 7.0, 7 ° to 10 total (120 ppm to 160 ppm) and total hardness in temperature between ° ° 75 to 75 degrees Fahrenheit.
Keepers don’t use filters (they change a lot of water!) But back snags or sponge filters are recommended for the average hobbyist. Use an aquarium heater to maintain an appropriate temperature, maintain optimal filtration, and perform 10% or 25% weekly water changes every two weeks using an aquarium water changer. Aquin or siphon gravel vacuum. Be sure to treat the tap water with aquatic water conditioner before filling your aquarium.
Are killifish schooling fish?
Naturally, killifish fish are not fish schools and do not exhibit any kind of school behaviour. However, starting with a pair is always a good idea. Also, it is up to you to decide whether to keep these fish in a group or not. Killifish will be comfortable with both options as long as you have a huge tank.
Killifish are mostly calm and shy fish although they are muscular, they usually do not show aggression towards other tank mates and are good community fish under certain conditions.
Although male assassins occasionally turn into provinces and begin to defend their place. If you keep two males in a small aquarium of the same species, the dominant males will probably try to drive out the other males. It can probably cause injury or even death for the weakest person.

Women, on the other hand, are particularly shy and do not show aggressive behaviour towards other fish. Although they are not as bright and colourful as the male fish, they will do well with others. Another advantage of having girls is that they produce more fish through breeding, which is why most people buy killifish in the first place.
Killifish Compatibility with Other Fish
Due to their calm nature, these fish can easily be kept with fish of the same size and choice of water. Still, there are a few things you need to make sure before mixing kills with other fish.
First, make sure the other tank mates aren’t too big. Since most species are small to kill, it will be a difficult time for them to defend themselves against invasive fish larger than them. Therefore, it is important to place them with other shy fish so that there is no fear or aggression.
Other than that, it’s essential that all your fish like the same water situation. Since killifish are primarily freshwater fish, they are comfortable with other freshwater fish of similar nature and size.

Can killifish live with bettas fish?
I want it to be very clear from the start. No, two betta fish should not live together.
If you think that two beta fish are identical in terms of environmental requirements and food, they will live better together. This is not true, especially when it comes to two male beta fish.
Betta fish are very regional. In addition to the two male betta fish fighting and the end of injuring each other, the mere fact that they share the same space will put tremendous pressure on them. And a stressed beta is more likely to fight their stress.
Unlike its male friends, the female beta can stay together in the same tank. A tank of multiple female beta fish is called a beta fish sorority tank and they are beautiful.
However, they are still aggressive and regional. So even when it is possible it is difficult and requires a lot of effort and attention of the owner
So if you are not an experienced fish farmer, I do not recommend having a beta fish sorority tank first.

On the other hand, non-annual fish are related to the common river that does not dry up. Therefore, they survive in annual killifish for 3 to 4 years. Thus, in aquariums, non-annual fish can live up to about 5 years.
Should you keep killifish in pairs or groups?
You can keep both pairs or groups. One pair of killifish may be ideal for beginners because they can reproduce too much. If you choose a group, you need to maintain a ratio of 2 females for each male.
