At the present time, aquarists know more than 10 species of fish from the genus Chanda. They are distinguished from ordinary fish by a completely transparent body, for which they were actually called solar perches.
Solar perch are home to brackish and freshwater bodies of Eastern Africa, South and South-East Asia.
Aquarists have already known about glass perch for a very long time, and interest in these fish does not fade. The great popularity of glass perch among foreign aquarists due to the transparent body, so that an inquisitive aquarist can examine the entire internal organs.
Under natural conditions, the fish grows no more than 7 centimeters in length, but in aquariums they are half the size.
In adult males, the body has a beautiful golden tide, and if the fish are fed with caratinoid feed, the color becomes generally orange-yellow, and the odd fins have a bright blue edging. Males – silver with a slight sandy tint.
The same color and young.
If you put a flock of fish in the amount of 10 – 12 pieces in a 100-liter aquarium, in which plants and bright light are densely planted, then you will have an unforgettable aquarium. However, you can fully appreciate the color of fish only in reflected light.
Young perch are trying to keep the pack, trying not to sail away from the dark stones. To heighten the effect, the ground in the aquarium should also be of a dark color.
The optimal substrate for the full disclosure of the color of this fish is coarse sand or the finest dark gravel.
The conditions of the sun perch are as follows:
- Water hardness 8 – 25 degrees;
- Active reaction environment 6.5 – 8.5 pH;
- Temperature 20 – 26 degrees (possible short-term increase to 30 degrees);
- High-quality filtration and aeration of the aquarium + weekly water changes for fresh.
You should always remember that glass perch loves old and clean water with a stable biological balance. Therefore, it is not recommended to allow abrupt changes in hydrochemical parameters of water. Substitution should be done in small portions and gradually.
Perch eat almost any kind of live food. In the diet should include bloodworm, cortex and various zooplankton organisms.
Sunny perch reaches sexual maturity at the age of 6 months. By the time of puberty, the flock gradually begins to “crumble.”
An overdressed male chooses a suitable place for himself (as a rule, a small-leaf bush, for example, a Japanese glare or a bunch of Javanese moss) and jealously guards him from annoying males. If a female who accidentally swims into the possession of a male, he immediately begins the marriage dances and invites her to the light.
It is better to engage in the breeding of glass perch in small aquariums, where it is necessary to place a shrub of a small-leaved plant, for example, a Guadalupe naiad or a moss crystal mass. If the problem with plants, you can put a bunch of fishing line.
To stimulate spawning, females and males need to be seated in different containers, gradually adding fresh water (settled out for a week) and raising the temperature to 28 degrees. In the previously prepared spawning several producers (one male and two or three females).
Females should have a swollen abdomen, and males are active with a bright color.
Fish spawn every day for 3 – 4 days, at the end of which the producers must be removed from the aquarium. In one sitting, females spawn up to 5 eggs, which are instantly fertilized by the male.
Fertilized eggs stick to the leaves of aquarium plants, or settle to the bottom of the aquarium. During the day, a couple of producers can spawn a large number of times.
The average fecundity of a glass perch female is up to 200 eggs, the maximum is 500 to 600 eggs.
In the process of spawning, producers need to be fed with live food, as this will safely affect the well-being of producers and significantly increase their activity. After a day, small larvae hatch from eggs, which after two days can already independently swim in the aquarium.
From this very moment the young need to start feeding. When feeding young stock, it is not possible to allow sudden changes in the water temperature in the spawning tank. Lowering the temperature leads to the fact that the fry become lethargic and inactive, they eat poorly, and may die as a result.
You must understand that a stable water temperature in a spawning aquarium is a fundamental factor in the success of rearing.
It is very important to observe the feeding regime and the quality of the food itself. Glass perch fry are quite voracious, so you should have plenty of food in stock.
In the aquarium it is necessary to organize a weak current so that the feed constantly moves around the aquarium. A gaggle of young perch will grab a passing by feed. Before starting to feed, you must sort the feed by size.
If the fry swallows very large prey, he may die. It is better to feed the fish in small portions of medium-sized feed.
When growing glass perch fry, it is recommended to organize a round-the-clock muffled light in an aquarium. The water level in the spawning should be no more than 20 centimeters. The first few weeks of glass perch life are the most important.
The best food during the first days of life is rotifers and live dust. Two weeks old fry can be transferred to the cyclops nauplii.
With a body length of 1 to 1.5 centimeters and an age of 2 months, perches are transferred to adult fish feed. With good and active growth, at the age of three months, the fish already have the first signs of sexual dimorphism. As neighbors for glass perch, you can select fish of similar sizes.
Fishes peace-loving and periodic skirmishes between males are harmless in nature, only in the rarest cases are there any slight damage to the fins.
In cases of malaise, overfeeding and the appearance of lethargy, the water in the aquarium with perches should be salted, gradually bringing the salt content in the aquarium to 6 ppm. In addition to the species of Chanda Ranga aquariums, other larger relatives are very often found. For example, in the collection of the Moscow Zoo for a long time lived Commerson perch living in freshwater bodies of northern Australia and East Africa.
The maximum body length of these fish is about 10 centimeters. Also there are glass from the island of Sumatra called Chanda wolfii, which is considered the largest (up to 20 centimeters in length) and yellow Chanda hails from Thailand and India.
If there are no fishes in the middle and bottom layers in your aquarium, settle a flock of glass perches into it and you will be happy.
