Ktenopoma Anzorg is a small freshwater tropical fish of the labyrinth family. The main background can be greenish, orange or brown, and most often is a combination of them. Body color also depends on the fish habitat. The tips of the dorsal and anal fin have a white edging, the caudal fin - from translucent brown to black. There are dark spots near the eyes. Males are larger and colored brighter than females, especially during spawning. The dorsal and anal fins of males are more developed and pointed at the ends. The body of the fish has a slightly flattened elongated shape up to 7-8 cm long. Six vertical brown or black stripes cross the body and pass through the anal and dorsal fins.
The natural habitats of the fish are slowly flowing rivers and streams in West Africa (Congo, Cameroon, Angola, Zaire), with soft, slightly acidic water and abundant vegetation. Fish hide near the bottom in thickets of aquatic plants near the coast, so they are difficult to find.
The fish feeds exclusively on insect larvae, small crustaceans, and fry of other fish. In aquarium conditions, they can be fed with bloodworms, brine shrimp, guppy fry, chopped earthworms. Food can be both frozen and live. Flake food fish eat poorly. A feature of the absorption of food is that the fish hides in darkened shelters and waits for the larva to swim closer to the reach zone. Then he actively attacks the larva and eats it. After feeding, the fish again go to shelter, where they calmly digest food.
Maintenance and care
Anzorg ctenopoma is characterized by secretive behavior, so it is well suited for quiet aquariums, gets along with similar small, inactive and bottom fish. In the aquarium there should be an artificial shelter - driftwood or cave. The fish does not adapt well to new conditions and can get used to a new aquarium for a long time, it is difficult to endure transportation. Aquarium lighting should not be bright; shaded areas are needed. pH of the water is in the range of 6.0-7.5, hardness is not more than 20 degrees. Water temperature - 20-26 degrees. The aquarium should have a filter, best of all, with a peat filler for acidifying water, and an aerator. Since the fish breathe not only dissolved in water, but also atmospheric air, which is typical for all types of labyrinths, the upper part of the aquarium should be closed to protect against drafts.
In large groups, Anzorg ctenopomas often lay eggs without creating any additional conditions. The onset of spawning can be determined by the bright, shiny color of the males. The male and female are planted in a separate small aquarium with plants, in which the fish build a nest of bubbles. The nest is usually attached to the underside of algae leaves. The temperature of the water must be maintained within 26-28 degrees, aeration - in small bubbles. The female can lay up to 600 eggs, after which she is removed from the spawning grounds, as the male perceives her as a threat to future offspring and exhibits aggressive behavior towards her. A male takes care of a nest with eggs. Weekly need to produce a water change of 20-30%. After 1-3 days, fry appear from the eggs. Hatching tiny fry are fed with nauplii (Artemia larvae), rotifers or infusoria 3-4 times daily. The male must be jailed, otherwise he can eat offspring.
After a couple of months, the fry grow to a centimeter in length. At the same time, adult coloring begins to appear in them.
