Koala scalar: maintenance and care
Koi angelfish is a fairly common and beloved by many aquarium fish, which is distinguished by its bright and attractive appearance. It lives in the rivers of South America, but is often found in the Amazon and Orinoco, in bodies of calm water.
A scalar with such an unusual name “red devil” is one of two varieties of another breeding species - red scalar. The latter is also the result of selection of koi scalar (red-headed), by conducting a selection on the presence of red fish in the color. But all the varieties of this aquarium fish began with three natural forms.
The red-headed koi scalar has a red pigment in its genes, which the breeders “concentrated” by the selection method and received the “red devil”, which accumulated a large amount of pigment.
This red angelfish has a second name - “red phantom”. In some places, there are no scales on the body of the fish, which gives rise to unique visual effects.
The terrible name does not reflect the nature of these magnificent fish: they are completely peaceful and calm under good conditions.
A bright red color is not peculiar to the appearance of a scalar; breeders have a great desire to make the color of this scalar as intense as possible red.
In order for the red devil scalar to have a beautiful bright red hue, it is very important to ensure that it is properly fed.
The main condition for the selection of feed is the content of the right amount of coratinoids in food. Crustaceans (cyclops) and fortified feeds (flakes) are the main sources of carotene.
Eating scalar these foods helps to enhance the natural color of their scales. Red scalar has a special background color, which must be strengthened as the fish grows older, and maintained in the adult state.
Considering the need for coratinoids, we can say that the red angelfish aquarium fish is very demanding on food. If the breeder has a desire and goal to maintain the color intensity of fish scales, it is necessary from childhood to provide these fish with special feeds.
Staining of red scalars occurs gradually, and only at the time of puberty (age one year) does it reach maximum brightness. But if you do not pay enough attention to the diet of your pets, then the fish fade and lose their attractiveness.
Aquarium Scalar Care
This type of koi is quite large. In a large tank, its length can reach 15 cm and its height 25 cm. The body of the koi scalar is laterally compressed, and the fins are very elongated and pointed. The ventral fins of the scalar are thin and long, and the rays of the caudal fin above and below are much longer than the others. The color of this species of fish is very bright: black, milk and silver spots stand out against the main yellow background, and the back has a reddish tint.
Koja sklyarii do not require special maintenance. They will feel great if:
- the tank for the aquarium wakes up about 70 liters (for two fish);
- 8-15 percent hardness (running, standing water is fine);
- a neutral or slightly acidic environment is better;
- good filtration and aeration of the aquarium will be installed;
- high water temperature (25-30 degrees);
- a large amount of greenery, in which the sklyari can hide.
Koi scalar compatibility with other fish is pretty good. These are the calmest and least aggressive fish. However, it is worth remembering that scalars feel best next to individuals of their own species, and their lifestyle is pack-like, which explains why that they feel most comfortable when their number in the aquarium is more than eight. They can treat other fish with fear and constantly run away and hide from them. Therefore, the best neighbors for them will be species of fish, approximately the same size and lifestyle with them. For example, various species of bottom fish or gourami.
Conditions of detention
Minimum aquarium volume: 115 liters;
Temperature: 23-28 ° C;
Carbonate hardness KH: 1-5.
In an aquarium with koi scalars, there should be soft, slightly acidic water and plenty of living aquarium plants. You can use stones and driftwood as decorations, but leave a place for swimming.
Koi scalar is fed a variety of feeds, both high quality dry flakes and live and frozen diverse feeds. Feeding should be several times a day.
Water changes should be at least 20% once a week, but to maintain the best health, you can make changes up to 50% of the volume of the aquarium.
