Lion head crucian

The Tench (Tinca tinca) is a freshwater fish species found in flowing waters and lakes in Central and Eastern Europe. Its name comes from its distinctive appearance, as it has an impressive dorsal fin, similar to a lion's mane. This fish is part of the Cyprinidae family and is one of the most well-known fish species in Europe.

The Tench has a cylindrical body, covered with large and solid scales. Adult fish can reach a length of up to 50 centimeters and weigh approximately 2 kilograms. Its color varies depending on the habitat in which it lives, ranging from brown, green, to gray, with shades of silver.

The natural habitat of the Tench includes rivers with moderate flowing water and sandy bottoms, but it can also be found in calm lakes and small ponds. It is an omnivorous species, feeding on aquatic plants such as algae and freshwater plants, as well as invertebrates, including insect larvae and crustaceans.

The breeding period of the Tench occurs during spring and summer, when the water becomes warmer. During this period, the fish lays its eggs in aquatic plants, where they will develop until they hatch. The Tench can live up to 12-15 years, depending on environmental conditions and food availability.

As a species, the Tench is appreciated by anglers for its fighting ability during sport fishing. It is also considered a delicious fish and is frequently prepared in traditional cuisine in the area.

However, in recent decades, the population of Tench has significantly declined in some parts of Europe, due to habitat degradation, pollution, and overfishing. In order to protect this species, conservation measures have been implemented, including the limitation and regulation of commercial and sport fishing. Measures have also been taken to conserve its natural habitat and reduce freshwater pollution.

To restore the population of Tench to healthy levels, it is important for governments and communities to continue supporting conservation efforts and promoting public education about the importance of protecting this beautiful freshwater fish.

In addition to its distinctive appearance and ecological significance, the Tench also plays a significant role in the context of cultural heritage protection. This fish has been fished and consumed for generations in rural communities in Europe, often being associated with culinary traditions and specific recreational activities in the area. By protecting this animal, we can contribute not only to the conservation of biodiversity but also to the promotion of cultural values and traditions of human communities.

In conclusion, the Tench is a freshwater fish species with a distinctive appearance, represented by its dorsal fin resembling that of a lion. This fish is widespread in flowing waters and lakes in Central and Eastern Europe and has significant ecological and cultural importance. However, in order to protect this species, appropriate conservation measures need to be taken and communities and governments need to be involved in protecting its natural habitat.

Facts

Origin

It was introduced to Japan from China in the 17th and 18th centuries. The Japanese produced specimens with a modified tail and smaller head size.

It is also known as Lionhead.

Feeding Lion Head crucian carp

It can be fed both dry food and live food. Pay attention to how much food you give him because he can get fat.

Food in large quantities in the aquarium is harmful to fish.

Features of the lion's head

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.

Lion head crucian is sensitive to low water temperatures. Due to their slow movement it is not recommended to be kept with fast fish such as Comet crucian.

If it is grown in an aquarium, it is recommended to have a large aquarium with good filtration. They are social fish so other types of non-aggressive fish are recommended.

It can grow up to 15cm long. They are usually available in orange, red, white, red and white, blue, black, white and black, black and red, naturan and chocolate color.

Breeding Lion Head crucian

The reproduction of Lionhead crucian carp is similar to that of Golden crucian carp.

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.
