Aquarium fish, belonging to the order Perch, suborder Anabasovidnye, Labyrinth family, a distinctive feature, which is the presence of the gill maze - this is a chocolate ktenopoma. Thanks to the gill maze, the fish is able to breathe air. Inhabit the bays of large rivers, ponds and streams overgrown with plants in Africa.
An elongated and flattened laterally body with a high back in length reaches only 10 centimeters. On the head are large round eyes and an elongated mouth. The fish has a brown to reddish-brown color with a dark marble pattern, in young individuals it is especially pronounced. The caudal fin has a fan shape, it, like the other fins, is painted brown, along the edge there is a black border. Along the edges of the gill covers are teeth. A black spot is located on the side of the fish; it turns pale during the spawning period. The female, unlike the male, has a full abdomen and a lighter color. The male has an acute dorsal and anal fin.
Chocolate Ktenopoma has a peaceful and calm disposition, gets along well with fish of similar temperament and size.
Fish are absolutely not fastidious in food. Chocolate prefers to eat ktenopoma as a live food, which can be used as worms, bloodworms, larvae and small fish, daphnia, cyclops, artemia and a crust, whether fresh, frozen or dry, or as substitutes for it.
Maintenance and care
For the comfortable content of chocolate ktenopoma, an aquarium of a species or a total length of 80 centimeters is suitable. It should be decorated with thickets of both floating and planted in the ground, plants, snags, artificial grottoes made of stones. The fish should be provided with diffused lighting, systematic aeration and water filtration. Also, one-third of the volume of water should be replaced weekly. The temperature of the water in the aquarium should not be lower than the mark of 22 degrees and not exceed 25 degrees. Chocolate Ktenopoma prefers to stay in the middle layers of water. When a fish is transplanted with a net, it can catch on it with gill teeth, to help it free, you should immerse the net in water and wait until the xenopoma detaches. Since chocolate ktenopoma breathes air, swallowing its bubbles from the surface of the water, it is necessary to cover the aquarium from above to prevent overcooling of air, as some individuals can catch a cold.
The ability to have offspring in chocolate ktenopoma appears from a year to a year and a half. At this time, you should select a pair of heterosexual individuals and put them in a spawning length of 60 centimeters, separately from other fish. In a separate aquarium should be a variety of shelters and plants. To stimulate the beginning of spawning, you need to pour fresh water into the spawning and increase its temperature by several (2-3) degrees. At this time, producers should be fed live food, preferably fry of other live-bearing fish. During the throwing of eggs, mainly in the evening, the female xenopoma keeps closer to the ground, at a time she is able to produce up to two thousand transparent eggs that contain fat. They float to the surface of the water. After the female has completed her task, adult individuals should be jailed. During the day, eggs hatch, and after a couple of days the fry can already swim and eat. Rotifers, ciliates, and larvae (nauplii) of crustaceans hatching from eggs can serve as a starting food for fry. Fry prefer to stay away from bright light, hiding from it in the leaves of plants and shelters.
