Akantoftalmus Sumatranus comes from small bodies of water in Southeast Asia and from the islands of the Sunda Archipelago. Like other representatives of this genus, the fish is characterized by a flattened body resembling a snake.
In the corners of the mouth there are three pairs of whiskers about 5 millimeters long.
The maximum size of this akantoftalmusa is 12 centimeters. Males have a more slender body than females. For the maintenance of this fish will require a medium-sized aquarium with diffused light and a large number of different shelters, where the fish will hide during the day.
Presence in the aquarium small-leaved plants (Javanese moss, Blix, Guadalupe Naiad, Moss Christmas), which will create dense thickets in the bank. Parameters of aquarium water should be as follows:
- Active reaction 6.5 – 6.8 pH;
- Water hardness 10 – 12 degrees;
- Temperature 25 – 27 degrees Celsius.
As neighbors for these fish, it is desirable to select medium-sized, peaceful fish, for example, rhodostomuses, nanostomuses, red neons, guppies, minors, ornatus. Why exactly haratsinovye?
The fact is that the representatives of this family prefer to keep mainly in the middle and upper layers, which is welcomed when keeping acanthophthalmus.
Acantoftalmus sumatranus is most active in the evening and at night, closer to dusk a small fish wakes up and it goes in search of something edible. It is in the evening that fish should be fed. As observations have shown, if a decrease in atmospheric pressure occurs, acanthophthalmos begin to show anxiety.
In order for hydrobionts not to leave their home, the tank must be tightly closed with a lid or cover glass.
In aquariums, where the stable biological balance of acantophthalmos can suddenly spawn. However, in order to get offspring guaranteed, it is better to use the proven method described by the Moscow aquarist L. Gudkov.
For spawning, a pair of producers aged from 1 year is selected. Females abdomen should be slightly enlarged, it will serve as a signal to the aquarist that caviar filling has begun. For breeding 3 – 5 individuals, you need a spawning aquarium, in which the bottom area will be about 1000 centimeters square.
With an increase in the number of fish, the volumes of the aquarium should increase accordingly.
Aquarium water in spawning should have a slightly acid reaction and a temperature of 26 – 28 degrees. The height of the water column in spawning should not exceed 25 centimeters.
The presence of aquarium soil is not a prerequisite, but the separator grid will have to be established. To manufacturers began to spawn, the fish need to make an injection of gonadotropic drug, taking into account the proportion of 100 – 150 IU per fish.
Since acantophthalmos are very mobile fish, and the body is covered with special mucus, you can hardly hold them in your hands without causing injury to the fish. Accordingly, before the injections, the fish must be transplanted into another container with a volume of up to 5 liters and drip a couple of drops of novocaine into the water.
Thanks to this step, the fish will fall into a stupor, and you can easily make all the necessary procedures without harming the fish.
When finished with the injections, the fish can be transplanted back to the spawning tank. After 8 hours, the males begin to actively chase females.
The male presses against the female and so they will swim near the bottom of the aquarium. And when they rise to the surface, the female will shoot a portion of caviar.
Unlike caring cichlids, negligent parents immediately begin to eat their calf, which will catch their eye.
After some time, the spawning process is repeated again. One sumacranus acantophthalmos female can sweep up to 800 eggs. However, as a rule, the female does not sweep the whole spawn completely.
Accordingly, so that the fish do not hurt, the remaining eggs should be drained. In order to avoid caviar suffering from saprolegniosis, it is necessary to add a fungicide preparation to the water. After a day and a half, the larvae begin to hatch from the eggs.
Four days after spawning, the fry are already able to swim and eat on their own.
From the first days after hatching the fry react badly to bright light in the aquarium. Accordingly, in order for the fry to feel calm, a pair of flower pots should be placed in the aquarium with youngsters, which will serve as shelter for the entire younger generation.
It is better to use “live dust” as starting feed for fry of acantophthalmos.
Young animals will develop fairly quickly and at the age of two weeks, the first pigment spots begin to appear throughout the body. Around this period of life, the auxiliary gill apparatus atrophies. By the month of life, the fry will have a body length of about 2 centimeters, after which they can be converted to a larger type of food – chopped shredder, cyclop.
Acantophthalmus sumatranus reaches sexual maturity at the age of one.
