The bottom of the aquarium should be gravel. The Telescope fish, like all Goldfish, produces a greater amount of waste than the rest of the fish, so we must have a good water filtration and the aquarium water must be renewed periodically. They are cold water fish, but that does not mean that we do not have a certain control over the temperature, which should be between 18✬ and 22✬, with a pH between 6 and 8. These fish tend to grow quite large, and also have a high life expectancy (10 to 15 years or more), so you can start with a minimum aquarium of 40 liters, although ideally a size of at least 80 liters would be better for a adult specimen and as we have more specimens, about 40 liters for each more specimen.įor example, if we want to have 4 fish, the size of the aquarium should be about 200 liters.

Within the Goldfish, it is one of the most rounded fish, it has a certain egg shape, it is plump and chubby.

In an aquarium, the Telescope fish does not usually exceed 13 centimeters, although in a pond (or a good-size aquarium) and with the right conditions, it can reach about 20 centimeters. It is believed that this Goldfish mutation has its origin in China (like almost everything that has to do with Carassius Auratus) around 1,700, when they began to be called Dragon Eye Goldfish or Dragonfish, although later they began to be raised in Japan, where they have been given the popular name of Demekin. The Telescope fish is also known as the Ojones fish, due to the main characteristic of its most striking morphology: its bulging eyes.Īs if we were talking about a bad joke, it turns out that they have pretty bad vision, so they are not good competitors for food.

The Telescope fish is a variation or mutation of the famous Goldfish, Carassius Auratus, Red fish, Goldfish … come on, the red carp that we see in hundreds of ponds, throughout the world. Common Name: Telescope Fish, Ojones Fish, Demekin, Dragon Eye Goldifish.
