Crucian Telescope

The Telescope Goldfish, known scientifically as Carassius auratus auratus, is a freshwater fish species characterized by its unique and attractive body shape. This species is part of the Cyprinidae family and is very popular among aquarium enthusiasts due to its unusual appearance.

Origin and habitat
The Telescope Goldfish is native to East Asia, especially China and Japan. There, this fish is known as "Demekin" in Japan and "Jingye-yu" in China. Over time, it has been introduced to other parts of the world and has spread to Europe, North America, and even Australia.

These fish can be found easily in almost any type of freshwater, such as lakes, ponds, rivers, and even water basins. They usually prefer slow or stagnant waters that are not too deep and have abundant vegetation.

Physical description
The Telescope Goldfish stands out with a variety of unique physical characteristics. This fish has a rounded body shape and a bulging appearance that gives it a distinct look. However, the most impressive and unique aspect is its pair of large and protruding eyes, which are responsible for its name "telescope". These eyes are round and located on the sides of the head.

The color and texture of the Telescope Goldfish can vary, and these differences are due to the varieties and selective crossings that occur during their growth in captivity. There are variants with smooth scales or with wrinkled scales, and the color can change from gold to black and even white.

The size of the Telescope Goldfish can vary, but generally they reach a length of about 15-20 centimeters. There can also be larger specimens, but this requires optimal growth conditions and adequate feeding.

Behavior and care needs
The Telescope Goldfish is a calm and friendly fish that adapts very quickly to aquarium life. These fish can be fed with anything from fish pellets to aquatic plants and algae. It is important to provide them with a varied and balanced diet to ensure they receive all the necessary nutrients.

Due to their large and protruding eyes, the Telescope Goldfish may have some difficulties with orientation and feeding. Therefore, it is essential to provide them with a suitable aquarium environment that includes sufficient vegetation and hiding places. Additionally, the frequency of water changes should be high to maintain good water quality.

Reproduction
The Telescope Goldfish can reach sexual maturity at around 1-2 years of age. During the breeding period, the male and female begin to change their behavior and body color. Males become more aggressive and colorful, while females increase the size of their abdomen before laying eggs.

After the eggs are laid, they are fertilized by the male and then covered with a sticky mucous. The eggs remain attached to aquatic plants or other objects in the aquarium. After approximately 3-5 days, the eggs will hatch and the larvae will emerge.

Importance and environmental impact
The Telescope Goldfish is a popular fish in aquariums due to its unique appearance and ease of care. However, it is important to be responsible in managing these fish. Releasing Telescope Goldfish into natural environments can lead to ecological problems, as these fish can become invasive and disrupt the balance of native aquatic ecosystems.

In conclusion, the Telescope Goldfish is an interesting and attractive freshwater fish that has captured the attention of aquarium enthusiasts over the years. With its large eyes and round body, the Telescope Goldfish is certainly a sensational presence in any aquarium. However, it is important to ensure that we provide adequate care conditions for these fish and to be responsible in their management to reduce the impact on the surrounding environment.
