Peaceful and friendly appearance, compatible with other fish of similar size and temperament. Larger species should be avoided. Optimal Clown killifish tank mates are from small tetras, neons, other Killifish, carp, other viviparous. They prefer to stay in a group, a flock of 8-10 individuals is welcome, in that group they show richer colors, and are not so shy in the presence of other species.
Males treat females very rough, so two females with one male should be placed on spawning grounds and make sure that there are shelters where the females can hide. Spawning takes place over several weeks and several eggs are laid daily on the plants. Juveniles are usually hatched in 8-18 days. 1-2 days before the expected hatching, the eggs should be placed in another vessel or on another spawning ground. At the same time, they replace the male; the females continue to spawn. Such a transplant can take place until the end of spawning (the next spawning period begins in a few weeks). in the spawning area, the producers have to be fed mainly with mosquito larvae. Sometimes breeders are kept separate and placed every 2-3 weeks for 2-3 days in the spawning area; in this case, they must not be fed in the spawning area.
Clown killifish (Epiplatys)
The genus contains 15 species of fish that are kept in aquariums. Under natural conditions, they live in stagnant and slow-flowing waters and even dry out temporary reservoirs of tropical regions of Africa.
Representatives of the genera Aphyosemion and Epiplatys most of the time in the upper strata and Nothobranchius in the middle and below. They lurk in the thicket and hurries quickly to the ceiling.
The structure of the fish is closely linked to the conditions of their life in nature. Externally, they are somewhat similar to the usual pike, for which they got their name. The body of the fish is strongly elongated, the dorsal fin is carried far back. The head is flat and forms a line with the front of the back. The Big Mouth is turned up. Men are brighter than women.
It is best to feed the pike with live food, dry food can be used as additional and in small quantities. Such fish as epiplatys prefer small live food in the upper layers of the water and refuse dry food. In nature, most of the diet of the African Pike consists of insects. This can also be taken into account during feeding.
Breeding Clown killifish is relatively simple. It should be taken into account that the incubation period of eggs in some species lasts from several weeks to several months.
Pike female lay eggs on various substrates lying on the water surface. For example, epiplatys prefer the roots of floating plants, and aphids can lay eggs both on the surface of floating plants as well as plants in the water column. Nothobranchius only spawns in the soil.
Clown killifish can be bred in two ways. The first is when the pair are left in a common aquarium with other clown killifish tank mates. Clown killifish are fed abundantly with a variety of foods, while at the same time monitoring the purity of the water. Water is gradually softened to the desired value (depending on the species). For most types of pH=5,8-6,5. You can install poor ventilation. Water temperatures for spawning killifish equal to 22-25°C, for aphyosemion-22-25°C. under such conditions, fish spawn regularly. The substrate with caviar is either taken for incubation in a separate vessel or waited for the fry to hatch in a common aquarium and then transplanted into the growing volume.
The second method is that a “nest” of the producers is laid on spawn – the females and males are kept separate beforehand, they are fed abundantly. The water in the spawning area should be the same as in the first case. On the surface of the water, there are floating plants, for example, riccia, and in the water column-several bundles of branches of Myriophyllum.
As a rule, spawning begins immediately after the planting of the producers. If the fish have been planted in the evening, they can be taken from the spawning ground the next day in the evening to remain separate until the next landing for spawning.
After 4-5 days, spawning is repeated and so-up to five times. Then the fish may rest for about two weeks, after which the spawning cycle can be repeated.
Depending on the temperature incubation time in clown killifish lasts 8-10 days and aphyosemion-12-20 days. Fry are fed with “dust” when the food grows, it is enlarged.
Aquarium for clown killfish
Clown killifish lives in stagnant or slow-flowing waters, and some-in temporary, drying reservoirs, so the best aquarium for them is a tank with a large water surface, a small water level (the length is two to three times as high and the width is equal to or slightly more than the height). Due to their small size and undemanding oxygen content in the water, these fish can be satisfied with small, low aquariums. It is desirable to keep each type of fish in a separate vessel. In a general aquarium, the diversity of Clown killifish tank mates should be limited to one genus.
The soil is ordinary gravel, preferably dark tones, on this background, the fish look spectacular. It is good to use fine gravel and put a thin layer of boiled peat on top. Lighting should be light and diffuse.
Clown killifish like “old” water and react negatively to the addition of freshwater and strong aeration. Stiffness does not matter much. Acidity should be kept to a minimum. This is achieved by ordinary boiling and settling of water for several days.
The temperature regime is of great importance. The optimal water temperature for keeping Clown killifish is 21-25°C.
In such an aquarium, you need to plant more plants: Watermilfoils, Cryptocoryne, Java moss, Thai fern, Najas, riccia, and other floating plants. The underwater interior is a good addition to a small well-cooked Willow driftwood.
