Comet Crucian

The comet goldfish is a popular fish in the rivers and lakes of Central and Eastern Europe. With its distinctive shape and attractive color, this fish has become a common presence in aquariums and a fascinating subject for animal lovers. In this article, we will explore the unique characteristics of the comet goldfish, its natural habitat, behavior, and care needs.

The comet goldfish, also known as "poisson rouge" (red fish) in French, is a freshwater fish that belongs to the family Cyprinidae. While it belongs to the same family as the common goldfish, the comet goldfish is characterized by its elongated, comet-like shape. It has a slim, tapered body that narrows towards the tail. One of the most recognized features of this fish are its long, filament-like fins, which move gracefully and give it a unique appearance.

The comet goldfish is native to China, where it was first bred and multiplied during the Tang Dynasty in the 9th century. It was brought to Europe in the 17th century and quickly became popular in the rivers and lakes of the region. Today, the comet goldfish is found in a variety of colors, from red and white to gold and black.

In its natural habitat, the comet goldfish prefers warm and clean water. It is often found in slow-moving rivers and lakes with abundant vegetation. This fish is known for its ability to survive in a wide range of conditions, but it thrives best in water with a temperature between 20 and 25 degrees Celsius.

The behavior of the comet goldfish is energetic and lively. It is a social species and is recommended to be kept in groups of at least three fish. However, in its aquarium, the comet goldfish can be aggressive and may attack smaller fish species. To avoid disputes between different species, it is important to select compatible species or keep only a few comet goldfish in the same aquarium.

As for food, the comet goldfish is an omnivore and feeds on a varied range of foods. In its natural habitat, it feeds on insect larvae, crustaceans, and algae. In the aquarium, it is recommended to feed it with specialized fish food and plant-based food such as spirulina flakes and finely chopped vegetables.

In terms of care and maintenance, it is important to provide the comet goldfish with a spacious and sufficiently large tank to move freely. It is also essential to ensure efficient water filtration, as these fish produce a large amount of waste.

In conclusion, the comet goldfish is a fascinating and attractive fish, appreciated both in aquariums and in its natural habitat. With its distinctive comet-like shape and long, graceful fins, this fish adds beauty and interest to any aquarium. With proper care and suitable living conditions, the comet goldfish can live a long and healthy life.










Later Mulertt became a caarsi breeder and author of books on goldfish. This was the first to place the comet crucian on the market to be bred and cared for.

Sarasa comet crucian carp characterized by red and white coloration that resembles Koi fish. It is also a very hardy species. Although originally from China, the word "sarasa" is of Japanese origin.

The single-tail Tancho is similar to the comet's silver-coloured crucian, but has silver body and fins and a red spot on its head

Feeding The Comet Crucian

One of the biggest problems you raise caring for crucian carp is the fact that they make a lot of mess, which can cause the concentration of ammonia in the aquarium to increase.

Goldfish would always eat but their stomach is much smaller than the cravings they have, for them it fits very well z icala: eyes are two and mouth is one.

That's why try to give them as much food as they actually need. Make them one serving, but it is preferable to feed them several times a day from this serving. Special flaky food for goldfish is a sufficient basic diet.

But it would be good to supplement it with spinach or boiled salad and live food such as shellfish, artemia or tubifex worms. To emphasize: give them small amounts at each meal. Due to the fact that they produce so much debris, be very careful about the quality of the water.

If the water in the pool becomes cloudy, you will have to change a quarter or more of the amount of water in the aquarium, such a change should be made weekly.

Give them less food. If they are fed floating goldfish tablets, care should be taken to soak them in water to swell. Otherwise the fish will swallow them dry and the tablets will swell in their stomachs. The belly of the fish will fill with air causing the development of swim bladder disease and the fish will float either on its side or with its belly up.

Goldfish will quickly learn that you are the one who feeds them and will come to the glass of the aquarium when you enter the room. They are fast swimmers and it is a pleasure to watch them.

Features Comet Crucian

For two goldfish it takes at least 75 liters of water. This aquarium might seem too big when the fish are small, but they grow quickly. The water must be chlorine-free. For this, it would be best to buy a chemical dechlorinator that you can buy from any specialty store.

A good filtration system is also needed to filter the water mechanically and biologically, and an air pump is also recommended to help the water circulate.

The heater is not needed if the temperature in the room remains within the limits of 18-24 degrees Celsius. These fish can also endure cold water, as long as the water temperature does not change suddenly in a very short period of time. If you put stones in the aquarium, which is not necessarily necessary, you must be careful to clean the debris fallen among the stones. For this you can use a vacuum cleaner connected to an air pump.

The comet crucian can be distinguished from the common Comet crucian by its unique, long and deeply forked tail. Under optimal conditions the tails can grow up to 12cm long.

The comet crucian is much more active than most other goldfish breeds. It is not uncommon to see a stylish comet crucian or why not, a playful and lively comet crucian.

Due to the nature of this fish and the ease with which it is cared for it is especially recommended for ponds and outdoor pools. They are often kept with Koi fish outdoors.

The comet crucian has a lifespan of 7 to 14 and can live longer in optimal conditions.

Breeding Crucian Comet

The reproduction of the comet crucian is similar to that of the Golden crucian.

Although considered very easy, the reproduction of Golden crucian carp still presents an inconvenience: the difficulty with which we differentiate the sexes of fish. Reproduction is similar for all varieties of Goldfish.

The first step to successful breeding is to make sure you have at least one viable breeding pair, although the ideal is to have 2 males for each female. Goldfish reach sexual maturity only at the age of 1 year, and sexual dimorphism is nonexistent in fish smaller than 8cm. In adulthood, females have a noticeably larger abdomen than males. Males develop small white tubercles on the gills and pectoral fins during breeding.

Some females will also develop such tubercles, but never as many as males. It is ideal to feed the fish with a variety of foods and in sufficient quantity to ensure that you will benefit from viable and healthy offspring.

Also, to stimulate reproductive activity, feed the fish with live food (for 2 months before spawning), keep the aquarium water clean and well oxygenated, at a temperature of 20grc. If you have the opportunity, it is very good to keep separate females from males until the mating season (spring), this procedure favors reproduction.

The spawning aquarium must be at least 100l (depending on how many breeding pairs you will use), filled with water with a maximum height of 30-40cm for the eggs to be deposited quickly. Stale and well-filtered water must be mixed with water from the spawning aquarium. If necessary, use a small heater to keep the water temperature at 20grC and a filter adjusted to the lowest flow rate.

The filter should not create drafts because the Fry are very sensitive. It is advisable to add a few groups of plants with dense leaves (Cabomba, Elodea), they will give the female the opportunity to take refuge from the male.

On the bottom of the aquarium, about 3cm high, you will need to place a frame with net that enters the aquarium fixed (without leaving spaces where the fish can insert their heads or bodies). The frame must be made of stainless steel or brass wire, and the mesh must have meshes of about 4-5mm.

The net will let the eggs pass and settle on the bottom of the aquarium, thus preventing the parents from eating them. You can also use a specially designed nylon mop on which the eggs will stick. Parents will immediately eat the eggs if they are not protected, so nylon mesh or mop is needed.

The aquarium will have to be ideally positioned in such a way that the first rays of the rising sun fall on it.

If you notice that the male is chasing the female and punching her with his snout in the abdomen, it means that it is time to prepare for reproduction. The Ideal is to use several fish, usually respecting the proportion of one female to two males. Fish should be introduced from the evening in the spawning aquarium.

Golden Crucians start spawning very early in the morning. Thus, the male will frantically " run " the female around the plants until it exhausts her, at which point the female will lay eggs that will be fertilized immediately with the male's milk. If the fish did not spawn, you can leave them in the aquarium until the next day to give them the opportunity to spawn. A female can produce from several hundred to about 1000 eggs.

Golden crucian eggs are sticky and will immediately adhere to the plants, the nylon mop or the bottom of the aquarium. They have the appearance of small transparent or brass spheres, with diameters of about 3mm and can be hardly noticeable on the bottom of the aquarium. If the female has laid eggs she will have a much thinner abdomen. After spawning immediately withdraw the parents from the spawning aquarium.

After 48-72 hours from spawning will emerge larvae that will catch plants and aquarium glass and will remain there for 1-4 days. When the fry begin to swim freely they will have to be fed (never before!) with naupli of Artemia, microworms or hard-boiled egg yolk.

If you use egg yolk, do not offer it in large quantities because it alters water very easily. Feed them about 4 times a day. All this time you will have to keep the aquarium very clean, remove the debris left behind parents and maintain the temperature at values of 21-22grc.

It is good to remove with a pipette sterile or rotten eggs so as not to infect healthy eggs. Compromised eggs look either like white, misty or black spheres. You can add a few drops of methylene blue to the water to avoid the development of fungi. The filter must be kept at very low flow rate.

After about 2 weeks the Fry will start to look like fish. After 4 weeks begin to change about 10% of the water in the aquarium. About 1 month after swimming freely the fry can be fed with fine flakes, and after about 3 months (when they measure about 3-4cm in length) they will begin to change their color. However, it may take more than 1 year for goldfish to develop their final color.
