Telescope goldfish overview

The Moorish fish or dragon eyes are delicate and sensitive to light due to its enhancement; in some cases, it can catch visual diseases that can cause permanent blindness. In addition, you have to be very careful with the food you give them; this species has a rather small stomach, so it cannot digest them quickly.

Telescope goldfish require a balanced and varied diet to strengthen their entire body, as well as the elimination of any health problems or diseases in the digestive system that could develop serious alterations in the future. The most convenient thing is to give them special products in small portions but in greater numbers so that their digestion goes smoothly.

The telescope goldfish is a fish that is at a disadvantage when it comes to feeding in the company of other species, so it is important to throw the food at a short distance so that other fish cannot take it away. In order for females to reproduce eggs, it is necessary to find a larger aquarium to prevent other fish from hurting them.

Its main characteristic is due to the variety of eyes they have which are modified in the form of a telescope or Demekin, it also has a short, and round body with lines above that makes it striking.

Double fin count without taking into account the pectorals and the dorsal. For it to be able to swim the tail fin easily must be divided, the advantage of this species is that it can be obtained in a wide variety of colours thanks to the fact that it has been subjected to a fairly developed captive breeding.

Telescope goldfish lack low vitality as they are not very good at swimming, and they also have low visual restrictions that tend to affect over time. Through scientific studies, it has been proven that after three years of upbringing, degenerative discomforts begin to appear in sight, and in most cases, it causes blindness.

Despite these drawbacks, the telescope goldfish is still one of the favourites, which is why many people choose it. To produce more of these fish, a female and a male need to be brought together; then the visible eggs will remain attached to the plants until the laying is complete. They will be fed with daphnia, brine shrimp and dry food for their proper development.

Tips for breeding this fish

To keep the offspring of this genus in good condition, it is essential to give them a series of attention and care. Take note of the following recommendations:

Keep the aquarium away from light: due to the shape of its eyes, this fish cannot be in the light for long, so it is recommended to place the fish tank in a dark place. Otherwise, it can cause fungus in the eyes until causing blindness permanent.

Temperate water: for the young of this species to be saved while they grow, care must be taken with the water, due to their low vulnerability they are not able to resist sudden changes, so the idea is to fill the aquarium with warm water.

The behaviour of the telescope goldfish

The dragon eyes, Moorish fish, or telescope goldfish is characterized by being a very peculiar species within the aquarium world. Despite requiring special care due to its low vulnerability, it is represented as a calm genus with developed captivity. There are quality specimens with intense colours that expand towards the fins to be more striking. Most of the time he is still and appreciates the company of the person who is watching him from outside the aquarium. You can put some companions of the same species or other similar ones, but that is not the kind that swims fast, because the telescope goldfish swims slowly and the others can take its food by attacking it at the same time.

How a telescope goldfish behaves

Telescope goldfish belong to the omnivore family, so they tend to devour all the food that is provided to them. When it shares its natural habitat with other fish, it does not usually bother or attack them, so it is recommended not to incorporate other species of hot water since they can attack to warm up.

This species needs special care to survive and develop correctly. Therefore they require good quality of warm and clean water to avoid infections by pests or accumulated bacteria. In addition, the water must be in constant motion to help you swim alongside a mediated current that contributes to better visibility.

Recommendations to take care of them

For this type of genus to reproduce freely, it is necessary to opt for a larger aquarium with 60 to 80 litres of water. It is also important to fit a sponge filter that generates short currents. When the eggs are laid within the habitat, it is best to remove them and place them in another tank to not eat.

This species is usually very peaceful, but if you make sudden movements outside the aquarium, they can get stressed due to its low focus. To keep them in good condition for as long as possible, constantly check your eyes as they are prone to infections.

Aquariums for telescope goldfish

Fish tanks for telescope goldfish

Telescope goldfish have double wings. However, this does not mean that they can swim perfectly since, as we explained previously, it is difficult for them to swim due to their low visibility. To facilitate their development, it is recommended to opt for a large fish tank that is not overloaded with pointed objects. Ideally, place natural plants so that you can swim freely without tripping or hurting any part of your skin.

The aquarium must be cleaned frequently to avoid the accumulation of bacteria; in addition, the water temperature must be warm since the telescope goldfish does not resist living between 10 ° and 24 °. If left at temperatures higher than these, the fish can die in a few hours. An air or bubble pump can also be used for excellent oxygenation.

Aquarium accessories

Be very careful not to place a filter that generates intense water currents since it can suck the fish until it dies, and its care only requires the following:

The utmost care must be taken with the water placed on it as telescope goldfish do not resist significant temperature changes. The idea is to fill the aquarium with warm water in this way; you will not need to use a thermostat to regulate the temperature every time you change it.

A more natural habitat shouldn’t carry it with sharp or large objects, the telescope goldfish has poor vision and can collide with them. Neither should you put a too extensive filter to form strong currents of water since this species is not a very good swimmer. Otherwise, it can swallow it, ending its life.

Basic care you need

The best thing you can do to keep your fish healthy and develop correctly is to place natural plants inside the aquarium that may be able to control the nitrogen inside it. The advantage of using plants is that they are flexible, allow the fish to swim without any problem and do not cause damage when hitting them. As for food, the correct thing to do is to give them special products in small quantities due to their low digestive capacity.

It should be remembered that telescope goldfish are omnivorous, but it is better to give them a food that contains a high concentration of vegetables, or, failing that, that is totally vegetable. It should be noted that the more years they have, the less they consume.

The rich and varied diet is the key to their growth and reproduction. When they are fed with harmful products, they suffer health problems that focus on the swim bladder, which is the most vulnerable part of this type of fish.

When this species is alone, its appetite is minimal; the reason is evidenced in the little stimulated activity that it has and the lack of chemical secretions that is caused when it finds a mate to reproduce. Therefore, the diet is also related to the amount of fish that are around it.
