Black Moor Goldfish Best Care Guide – a little eye with black scales

Goldfish have been kept as pets for an incredibly long time. Therefore, it is not at all surprising that thanks to the work of breeders in our time, we have a huge variety of breeds of goldfish, sometimes so different from the original forms that it is difficult to believe in their relationship. One of the trends in goldfish breeding is the production of forms with enlarged eyes, called telescopes. In our article we will tell you about the most popular variety of this breed with black scales.

General information

Black telescope (Black Moor Goldfish) – short-bodied breeding form of goldfish , a distinctive feature of which are protruding eyes and uniform black color of the scales. It is one of the hardiest and most popular breeds among Aquarius.

Despite the large size of the eyes, these underwater inhabitants are not distinguished by sharp eyesight. Also, fish often damage their eyes, so the correct selection of aquarium decorations and roommates is very important.

It is worth noting that bulging eyes are a persistent feature in black telescopes; when crossed with other goldfish, it usually persists.

Black telescopes are cold water fish and are not recommended to be kept in aquariums with temperatures above 23 ° C.

Appearance

The black telescope has an ovoid body with a well-visible rounded abdomen. On the sides of the head are a pair of large protruding eyes, practical spherical in shape. A pair of nostrils and a medium-sized mouth are clearly visible.

The fins of the black telescope are long, often veiled. The dorsal fin resembles a sail, the tail fin is forked.

Body color – velvety black top and sides. The abdomen is light – golden or copper. Individuals with the most black color are valued above all, but in order for the color of the fish to be preserved, they must be kept under certain conditions.

For example, if telescopes live in warm water, their black outfit will change to gray. Discoloration is also observed in older individuals and when kept in inappropriate conditions.

The maximum size of a black telescope is 20 cm, but at home it usually does not exceed 15 cm.

Habitat

The black telescope is a human-made selection form. In nature, such fish cannot be found. The goldfish is considered the ancestor of the goldfish, but telescopes are completely different from their large and slender natural ancestors.

The butterfly breed of goldfish is a type of telescope, and its main distinguishing feature is a forked tail fin, which, when viewed from above, resembles the spread wings of a butterfly.

These fish were obtained by Japanese breeders at the end of the 20th century. In keeping and feeding, they are completely identical to ordinary telescopes.

Care and maintenance

Black telescopes are not difficult to maintain, but they have certain specifics.

Before starting your telescope, be sure to think about the appropriate volume of the aquarium. On sale most often you can find fish 3-4 cm long, but this should not mislead you. One black telescope specimen should have at least 40 liters of water. Only in this case the fish will be able to grow to its maximum size.

And it will be easier to maintain balance in such an aquarium, because telescopes cannot be classified as “clean”. They eat a lot, dig up the soil, which in a small aquarium can lead to rapid water pollution. And this is a direct path to fish diseases. You can keep black telescopes one by one, but it is better to stay with a group of 3-5 individuals. True, in this case, an aquarium will be needed for 150-200 liters.

Sand or large pebbles are used as soil. It is best if they cannot fit the fish in the mouth. Cases of ingestion of soil particles with the subsequent death of a pet are known. Particular care should be taken to remove the decorations.

They should not have sharp edges, protruding parts. After all, it is about them that it is so easy to damage the delicate eyes of black telescopes. Large rounded stones, smooth grottoes, artificial silk plants are well suited. The swimming area should be as large as possible.

Aquarium plants, especially those with delicate leaves, are usually not planted with black telescopes. Goldfish are phytophages, so they will eat and dig up greens. The exception is rigid -leaved species – Anubias , Indian fern , Vallisneria .

Due to the rapid accumulation of waste, it is very important to provide powerful filtration in a black telescope aquarium. A combination of external and internal filter is ideal. However, a strong current will be useless, telescopes are unimportant swimmers.

Do not forget about active aeration, because oxygen is needed both for breathing of such large fish, and for the vital activity of beneficial bacteria that process waste of aquatic inhabitants.

Once a week, you need to change 20% of the water in the aquarium. Use Tetra Goldfish Aqua-Safe Conditioner to avoid sedimentation and keep your pets safe from hazardous compounds in tap water. It instantly makes fresh water suitable for fish life by removing chlorine and heavy metals from it. The dosage is 5 ml for every 10 liters of replacement water.

Compatibility

Given the vulnerability of the eyes of black telescopes and their optimum temperature, the ideal option for keeping is a species aquarium.

But if you wish, you can also choose a company for these fish. The best choice would be other short-bodied breeds – veil – tails , oranda , stargazers , water eyes . Planting active goldfish with black telescopes is strongly discouraged. The fact is that big-eyed fish, due to their slowness, will lose the competition for food and remain hungry.

Most tropical fish will be uncomfortable at temperatures close to 20 ° C, while other species (for example, barbs and some haracin fish) will not mind biting the eyes and fins of telescopes. Predators for sharing with black telescopes are also excluded for obvious reasons.

Feeding the telescope black

Feeding black telescopes at home is easy. They eat dry food very well. As a main food, it is best to choose a quality dry food for goldfish. For example, Tetra Goldfish Gold Japan has been specially formulated for breeding goldfish from Japan. The food in the form of mini sticks gradually sinks to the bottom. This is where the fish usually prefer to look for food. It is rich in plant components that are very important for the digestion of goldfish.

The basic food for all Tetra Goldfish is also well suited. It comes in several forms (flakes, chips, granules, sticks), among which it is easy to choose the one that pets like the most.

And for “dessert” you can offer the fish Tetra FreshDelica Daphnia – Daphnia in nutritious jelly. It will definitely suit your black telescopes.

The use of high quality ingredients in the production of Tetra feed ensures maximum digestibility and a reduction in fish waste, which allows the water to remain clean for a long time. The vitamins in the feed provide healthy immunity and longevity.

It is necessary to feed black telescopes several times a day with such a portion of food, which will be completely eaten in 2-3 minutes. It is recommended to arrange a fasting day once a week.

Reproduction and breeding

It will take several manufacturers to breed black telescopes at home. Sexual dimorphism in fish is not pronounced. Only before spawning, you can notice changes: in the female, the abdomen from the eggs is rounded, and in the male, white tubercles – tubercles – appear on the gill covers and on the head. Before breeding, opposite-sex fish are recommended to be seated in separate aquariums for 1-2 weeks and fed abundantly.

For spawning, you will need a spacious aquarium with a volume of 50 liters or more. It is necessary to install a small filter and aerator in it. A separator mesh is laid at the bottom, and bunches of small-leaved plants are placed on top. This will reduce the risk of the parents eating their own caviar.

One female and a couple of males are usually planted for spawning. Spawning is stimulated by an increase in temperature and a massive water change. The fertility of the female is curled on the age and condition of the fish and can range from 2 to 10 thousand eggs.

After the completion of the process, the producers should be deposited, and an antifungal agent should be added to the water, because many eggs are affected by the fungus and die.

Incubation lasts about 48 hours, then immobile larvae are born, which after 5-6 days pass to independent feeding.

Surprisingly, young black telescopes do not have bulging eyes, they begin to appear only six months after birth.
