Good day, colleagues. We continue acquaintance with representatives of the Cichl family and on the agenda we have several interesting representatives of this very extensive species.
First of all, let us consider tetrakantus tsikhlazomu, and then we will in the queue to disassemble all the other fish.
The first descriptions of this cichlasoma were recorded as early as 1831. Due to the current level of development of aquarium art, this fish has spread widely throughout the world, only now it has not been able to reach Europe on an industrial scale.
And yet, the bulk of these fish remained in their historic homeland.
On the territory of the Soviet Union, this fish was first brought to Moscow in 1989, and a few years later aquarists got their first offspring from it. To our great regret, we got traders, the lack of body shape of which was compensated by a bright and spectacular color.
There is a scattering of anthracite stains on a shiny pearl body along the body of the cichlasome, and the head resembles a ritual mask. Completes the composition of a large spot near the gill cover. The color of males is much brighter than that of females, the fins are pointed and females are much smaller than males.
The maximum body length of the fish is 25 centimeters, but more successful spawning were obtained in fish whose length did not exceed 12 centimeters.
The key problem in the breeding of this cychlasoma is the creation of a contact pair. Ideally, you should have a harem raised from fry, which makes it possible for the male to spawn in turns with several females.
In the case of the slightest hassles, females are better to be deposited from the males behind a transparent partition.
For successful breeding of cychlasmas tetrakantum you must have a spawning aquarium with a volume of 150 liters. Stimulation to spawning is fresh water, elevated water temperature up to 30 degrees and abundant three meals a day with live food. Spawning substrate can be polished stones or ceramic pots.
The standard fecundity of females rarely exceeds four hundred eggs. In the ideal case, parents should take care of their eggs and fry for 2 months, but this happens very rarely.
In the case of artificial incubation, the young fry are fed with microplankton one week after prokleva. By the month of life the brisk fry reach a length of up to 15 millimeters.
In fry and young fish, black vertical stripes are much brighter and clearer than in adult congeners. To avoid cannibalism among fish, they need to be sorted once a quarter.
Tetrakantus is quite demanding for the conditions of cichlasoma content. If the water in the aquarium is turbid and its temperature is below 22 degrees, the fish will quickly become covered with ulcers, which provoke the development of secondary infections (ichthyophritiosis and chylodonellosis). The fastest treatment is to use erycycline solution (25 milligrams per liter of water) and the disease will be neutralized within 5 days.
Under optimal conditions, the fish can live for up to 10 years.
This fish first appeared on the territory of the Russian Federation in 1991. Three random fry inexplicably fell into the group of yellow cychlosis Pasione.
The homeland of Torikht is the basins of the Mezcalapa and Tacotalpa rivers, which flow into the Atlantic Ocean. The hydrochemical conditions of the habitat of Toricht Geller are as follows:
- Overall stiffness 2 – 8;
- Carbonate hardness 4-7;
- Active medium reaction 7.2 – 7.8 pH;
- The water temperature is 23 – 26 degrees.
The young are painted in olive-gray tones with several transverse stripes. Adult fishes of a brownish-gray shade with a scattering of emeraldic points on the head, fins and body.
In the case of excitation, the number of bands increases to 8 pieces, but, as a rule, there are no more than 5 of them, and the fins turn orange.
Toricht Geller is famous for its meek temper and something like its behavior resembles a masked cichlase, which is known to us as Tsihlazoma Meek, but their throat fold is not red like Meeki, but orange with dark edges. The fish grows to 15 centimeters in length, but, as a rule, its standard dimensions range from 8 to 12 centimeters.
Torikht reaches sexual maturity at the age of one to one and a half. A fish can spawn both in a separate spawning pool and in a common aquarium, the main thing is that a couple of fish have at least 50 liters of water.
Spawning occurs on an open substrate with even grooves. The fecundity of females can range from 200-450 eggs. Masonry, as a rule, protects the male and female.
After spawning, about three days should pass in order for small embryos to be born, with which the female carefully looks after and carries them into the prepared pits in the substrate.
After 4-5 days, the youngsters begin to swim independently in the aquarium and eat. Starter feeds are rotifers, nauplii cyclops and artemia.
Two-month offspring, even under the condition of abundant and high-calorie feeding, do not reach two centimeters in length. A healthy moment for the young is the addition of methylene blue to the aquarium water, taking into account the proportion of 0.5 mg per liter of water. Adult Gellers can suffer from toxicosis, especially if they are fed with poor-quality pipe maker.
With good conditions, Torcht Geller can live up to six years.
