Akantoftalmus Kühl (Pangio kuhlii) – a fish with a very unusual body structure and bright color was discovered by Valenciennes in 1846.
It has many names: Akantoftalmus Kyula, koljucheglaz, pangio Kyula, acantik-snake, acanthus.
Found on the vast territory of south-east Asia: the Indonesian islands of Sumatra, Kalimantan, Java, in Thailand, Singapore and Malaysia.
It lives in fresh water bodies, in slow-flowing rivers and streams with a soft, oozy bottom and a large layer of fallen leaves.
The shape of the body resembles an eel, slightly flattened at the sides. Eyes are covered with a thin protective leathery film, spikes forked at the ends are located under them.
Three pairs of whiskers designed to search for food. Fins small, dorsal displaced to tail.
Body color can be reddish or yellow-orange with wide dark stripes, the number of which ranges from 10 to 20 pieces. The belly is lighter.
The females Acantoftalmus Kuhl (Pangio kuhlii) reach a length of 12 cm in contrast to the males, whose size is approximately 2 cm smaller. In females, the abdomen is denser and greenish caviar is seen through it, while in males the second rays of the pectoral fins and pelvic fins are thickened.
For 6-7 acantoftalmusov need a capacity of 50 liters. It is better to keep the flock, and, the more fish, the better their individuality is manifested and the freer they feel.
For the aquarium is not so much the volume, but the area of the bottom. A lid is necessary, as they are able to jump out of the water when frightened.
Be sure to a large number of plants (preferably small-leaved) and shelters of driftwood, pipes, stones and caves.
Floating plants are necessary to create shaded areas, as the eye thigh prefers subdued lighting. Fishes in search of food burrow into the ground, so it should be soft: sand, very fine and smooth gravel, peat boiled crumb.
Temperature: 26-30 ° C;
Stiffness: 5-10 ° DH.
The fifth part of the water is replaced weekly. Filtration with aeration is powerful enough to ensure the purity of the water in the aquarium without creating strong vibrations.
The openings of the filter should be closed with a net so that the fond of climbing into various cracks and mink do not get inside and not die.
Acantoftalmusy are very peaceful fish and feel comfortable with many non-aggressive species: tetras, corridors, rassets, guppies, neons, discussions, gouras and danios. Suitable for shrimp aquariums.
Unacceptable content with goldfish and cichlids.
A surprising feature of Acantoftalmus is its reaction to pressure drops: the fish arrange a kind of “dancing” in the water column.
Omnivores. They prefer live food – koretra, bloodworms, tubimmer. Sinking dry food (chips, pellets, tablets) is also eaten with pleasure.
Favored by the gelled feed – crank, krill and shrimp. 20% of the diet should be of plant origin.
In nature, spawning at the püggio kühl occurs during the rainy season in shallow clear waters. Spawning fish at the surface, and vymetannaya caviar falls and glued to the leaves of plants.
In captivity, reproduction of these fish in most cases occurs only with the help of hormonal stimulation with choriogonin.
The bottom area of a spawning tank should be about 1000 cm2. The water level is 20 cm. We need floating plants: pistes, Thai fern, cryptocorynes.
The lighting is weak and diffused.
Parameters of water for reproduction: 26-28 ° C, dH 5-15, pH 6.5-7.
Requires aeration with filtration, and the substitution of 10% of water daily.
The spawning bottom is covered with a net and a female with 2-3 males is launched into it. The female spawns portions, 10-50 pieces. The total number of greenish eggs can reach up to 1000.
After spawning, the calf remaining in the female drains.
Incubation continues for a day, after another 5 fry swim. At the initial stage, they feed on living dust, microterms, ciliates, Artemia, rotifers, in the future you can add shredded tubule and cyclops.
Sexual maturity reaches the year.
When creating favorable conditions for fish, Akantoftalmus Kühl (Pangio kuhlii) can live in captivity for 5-10 years.
The Pangio genus is one of the most specific among the Viunovs and is widespread throughout South and Southeast Asia with a species diversity that is considered to be much larger than is currently recognized and described.
This genus has countless variations, both within and between populations, although most of them have the same basic pattern of dark saddle-shaped marks, usually wider on the dorsal surface, along the yellow-orange base color.
All kinds of Acantoftalmuses have sharp and moving under eye spines, which are usually hidden in a bag under the skin, but come out when the fish are stressed, for example, if they are removed from the water. Therefore, it is necessary not to forget this, since they can become entangled in the net of a net, and larger species can injure human skin.
