Species Carassius Auratus

As you can now probably tell, the Telescope Goldfish originated, like most species of Goldfish, from China. This species was developed through selective breeding methods in the 1700s and soon became a favorite among fans of freshwater aquascapes.

The Telescope Goldfish then became abundant in more natural areas due to its fast reproduction capabilities. Today, it can be found in still or slow-moving bodies of water that are protected by shade and have a moderate amount of vegetation in almost all areas of China.

The scientific name of this fish is Carassius Auratus, though it may sometimes be referred to as a Moor Goldfish, Demekin Goldfish, Dragoneyes Goldfish, or dragon eyed Goldfish by aquarists and local shop owners.

Telescope Goldfish Care

Now that you have gotten to know the Telescope Goldfish better, you can move on to learning about how to care for these big eye Goldfish. This fish is relatively easy to care for, but it may nonetheless seem like a daunting task for beginners who have never tried their hand at fishkeeping.

In this section, you will learn all about the Telescope Goldfish’s diet as well as tips and techniques you can apply to better care and provide for the newest member of your freshwater aquarium.

– Diet

Telescope goldfish the wide eyed wonder fish of freshwater aquascapesThe first thing you need to know about the Telescope Goldfish when it comes to its feeding preferences and routine is that it is an omnivore. In the wild, Telescope Goldfish look for insects and small, soft-shelled crustaceans that they can eat with ease. They might also be seen feeding on tender plant or vegetable matter that comes their way.

However, as a fishkeeper, it is part of your responsibility to provide your Telescope Goldfish with a balanced and nutritious diet; the best way to do this is to mimic how and what Mother Nature provides.

That said, you can feed your Telescope Goldfish a mix of fresh or frozen cut-up meaty foods, commercial pellets, and flakes, as well as a couple of servings of vegetables. Offer it food two to three times a day, and then observe their feeding behavior for a period of time.

If you notice that it is not finishing their food and it just contributes to the aquarium’s waste, lessen the number of times you provide them with meals. On the other hand, if you notice that your Telescope Goldfish is becoming thinner or seem to be less lively, consider increasing its food intake. 

– High Protien Diet

For protein-rich meals, you can offer your Telescope Goldfish bloodworms, brine shrimp, tubifex, and even Daphnia. Feed this kind of food three to four times a week. As for vegetables, you can provide your Telescope Goldfish with bite-sized pieces of lettuce, spinach, boiled potatoes, and crushed pumpkin.

Finally, be sure to choose high-quality commercial Goldfish pellets or flakes. This type of food will make up the bulk of your Telescope Goldfish’s diet, so it is best to invest in a brand that is organic or as preservative-free as possible. Feed your Telescope Goldfish with pellets or flakes up to three times daily.

– Water Parameters

Below is a table that contains the key parameters needed to build an ideal Telescope Goldfish habitat. Consider these parameters before you purchase a Telescope Goldfish of your own, especially if you plan to keep the new fish in a community tank with other freshwater species.

Temperature 65 to 72 degrees Fahrenheit
pH Level 7.0 to 8.4
Water Hardness 5 to 19 dGH
Light Level Moderate
Substrate Medium or large gravel

– Tank Setup

Aside from ensuring that your aquarium has the right parameters, you also need to think about how many Telescope Goldfish will fit comfortably in your current tank setup. The ideal Telescope Goldfish tank size is 30 gallons.

This should be enough to house two or three Telescope Goldfish and still provide them with enough space to move freely and explore. While this kind of fish is neither territorial nor aggressive, you still need to provide them with ample space to move around and grow.

– Add Live Plants to Your Aquascape

You can improve the quality of your aquascape by including live plants that will not only beautify their surroundings but provide your Telescope Goldfish with oxygenated and filtered water to live in. Some of the best live plants to include in a Telescope Goldfish tank include the Anubias, Java Fern, Amazon Sword, and the Cryptocoryne Wendtii.

Keep in mind that Telescope Goldfish have a reputation for being quite destructive, so it would only make sense to include live plants that are either tough or self-propagate too fast for your fish to eat through the population. Whether you have a small aquarium or a large community tank, you should at least look into including one or more species of live plants to provide your Telescope Goldfish with a more natural environment.

– Keep the Water Movement Low and Slow

On the topic of creating an environment that is similar to the Telescope Goldfish’s natural habitat, another thing you should do is to keep the water flow in your aquarium low and slow.

Telescope Goldfish become stressed when they are placed in aquariums that have a strong water current. They can easily get sick or refuse to feed if they feel harassed in their enclosure. Adjust your water filter accordingly to accommodate your Telescope Goldfish’s water flow preference.

– Keep the Tank and Water Clean

Telescope Goldish, like other members of its species, are notorious for rapidly dirtying aquarium water. This is tied to the fact that they are voracious eaters, so they produce a lot of organic waste as well. Furthermore, Telescope Goldfish that are under constant stress may release more waste than their healthier, happier counterparts. Stressed fish are often the result of being housed in cramped quarters or with unsuitable tankmates.

If you have a small aquarium, you will need to perform minor water changes on a weekly basis to ensure that your Telescope Goldfish have fresh, clean water. In addition, you should also make it a habit to manually remove any debris or waste that you might observe floating around your tank.

You can do this at night time or late in the afternoon after you have fed your Telescope Goldfish. Getting into the habit of keeping a clean tank and high-quality water will pay off later as your Telescope Goldfish will certainly enjoy a longer, healthier life.

– Lifespan

Note that the average Telescope Goldfish may have a short life of only five years, or else enjoy a completely full life that lasts more than two decades. This will largely depend on the quality of food it receives as well as the consistent cleanliness of its immediate environment. There are other factors that contribute to lengthening or shortening the Telescope Goldfish lifespan which you will learn about in the other sections.

While the Telescope Goldfish is definitely one of the hardier freshwater species known to the fishkeeping community, it can still have a difficult time adjusting to poorly built tanks or become prone to illness because of a nutrient-deficient diet.

In order to maximize the lifespan of your Telescope Goldfish, you need to learn the ins and outs of caring for it properly. One of the key factors that affect the Telescope Goldfish’s lifespan is the amount of space it is given to grow and live in.

If you plan to keep your Telescope Goldfish with other freshwater fish, be sure to provide it with a lot of space to move around in. Remember: a Telescope Goldfish raised in cramped quarters is an unhappy fish, and an unhappy fish is most often a sickly one.

– Common Diseases

Although the Telescope Goldfish is one of the easiest freshwater fish to care for, it is not immune to health issues such as bloat, constipation, parasitic infections, and physical deformities due to accidents or underlying illnesses.

As such, it is imperative that you address any abnormal behavior or symptoms of sickness as soon as you notice them. Below are some of the common health issues that you might encounter with your Telescope Goldfish and how to resolve them.

– Eye Infections

If you notice that your Telescope Goldfish has a cloudy eye or has a cotton-like growth over one or both of its eyes, it probably has a bacterial or fungal infection. Both of these types of infections are caused by poor water conditions. You can address this issue by isolating the affected Telescope Goldfish immediately and mixing anti-fungal or anti-bacterial drops in its tank water. Such medications may be bought at your local fish store.

– Dropsy

The Telescope Goldfish is also prone to a health condition called Dropsy; this involves some measure of kidney failure so that the fish’s body is unable to process fluids properly and its body becomes bloated. Dropsy can lead to the death of your Telescope Goldfish if it is not treated immediately.

If you spot a Telescope Goldfish with an early stage of Dropsy, you do not have to isolate it from the main aquarium. Instead, provide that fish with high-quality food and encourage it to eat regularly; you may also mix supplements in the tank water to bolster the Telescope Goldfish’s immune system.

If your Telescope Goldfish has a more severe case of Dropsy, however, you may need to consult your local fish experts for the proper medication and administration.

– Parasitic Infections

Worms, lice, and flukes are just some of the parasites that might latch on to your Telescope Goldfish if you do care for it well. These parasites thrive in dirty and poorly-oxygenated water. They are usually introduced into the aquarium via low-quality food and fish that were not quarantined prior to joining the tank. To prevent this common health condition, you should make it a point to keep your aquarium clean and well-filtered at all times.

On the other hand, if you notice that your Telescope Goldfish already has worms, live, or flukes on its face, gills, or fins, then you need to treat the aquarium water immediately with a parasite-appropriate solution. Treat the entire aquarium instead of isolating the affected fish to prevent your other tank inhabitants from becoming the next parasite host. You can purchase parasite solutions at most local fish stores or at an aquarium supplies shop.

Tank Mates

Choosing the best neighbors for your Telescope Goldfish is easy once you understand some general pairing rules. Telescope Goldfish are neither aggressive nor territorial, hence,  you should always pair them with fish that have a similar personality. However, you also need to keep your Telescope Goldfish away from tiny fish that they might confuse for food.

– Ideal Tank Mates

Some of the best fish to keep with your Telescope Goldfish include large Catfish, lazy Loaches, and peaceful Plecostomus. Most of these fish will tolerate your Telescope Goldfish’s inquisitive behavior and voracious appetite. Additionally, these fish generally occupy the lower level of an aquarium, making room for your Telescope Goldfish to freely occupy the middle layer of the tank.

First, there is the Calico Telescope Goldfish which is so-named because of its beautifully mottled orange, black, and white body. This fish has a delicate, almost transparent set of fins that enhances its appearance whenever it moves about in the tank. Despite its unique appearance, however, the Calico Telescope is not known for its longevity as many fishkeepers have noted that its lifespan stretches from 3 to 5 years only.

Then, there is also the Butterfly Telescope Goldfish which is one of the most expensive types of Goldfish known to the aquarium community. It has a darker coloration than the Calico Telescope as well as fins that resemble a butterfly’s wings.

If you want to combine different types of Goldfish in a single aquarium, you may certainly do so provided that you group them according to their behavior and personality: active and agile Goldfish should not be housed together with slow or shy Goldfish.

– Tank Mates To Avoid

On the other hand, avoid pairing your Telescope Goldfish with small snails, shrimp, and small fish such as Minnows. These neighbors will only tempt your Telescope Goldfish to treat them as a delicious snack. You should also avoid housing your Telescope Goldfish with large and overly aggressive fish such as Cichlids and Oscars.

Cichlids and Oscars are large fish that are known for their highly aggressive temperament. They will not make your Telescope Goldfish feel welcome or safe. Your Telescope Goldfish will also likely put out too much bioload for your Cichlids and Oscars to stay healthy. These fish are not compatible with each other and are better off housed in different aquariums altogether.

Another fish to avoid pairing with your Telescope Goldfish is the notorious Peacock Bass. The Peacock Bass, like Cichlids and Oscars, has a strong and aggressive nature. They will probably tolerate your Telescope Goldfish for a short period of time before deciding to hunt them down or else harass them relentlessly.

Breeding

The Telescope Goldfish can be bred easily in a home aquarium if you keep a few guidelines and tips in mind. Before you commit to breeding your Telescope Goldfish, you will need to identify at least one male and one female to pair with each other.

Telescope Goldfish become sexually mature at around 12 to 14 months. The males develop white, pimple-like stubs near their gills and the females grow a deeper, rounder body to accommodate future eggs.

– Pre Breeding Care

Prepare the necessary equipment for breeding your Telescope Goldfish; this includes the main aquarium, a breeding tank, a sponge filter, a heater, and some live plants. Introduce your pair of Telescope Goldfish in a breeding tank that has been thoroughly cleaned and properly cycled. Then, increase the water temperature to around 74 degrees Fahrenheit.

You can offer your Telescope Goldfish breeding pair protein-rich food as well, to further encourage them to spawn.

Your paired Telescope Goldfish should begin to exhibit spawning behavior after spending 48 to 72 hours in the breeding tank. The female Telescope Goldfish will seek out a suitable plant or surface on which to lay her eggs. Shortly afterward, the male Telescope Goldfish will seek out the eggs to fertilize them.

– Post Breeding Care

You should remove the parent Telescope Goldfish once fertilization has occurred; reintroduce them back to the main aquarium. This will prevent the adults from eating their own eggs. You can then support the Telescope Goldfish fry by providing them with infusoria once they have become free-swimming fish. You can also feed your Telescope Goldfish fry with crushed fry pellets or flakes once after three to five days.

Expect that some of your Telescope Goldfish won’t make it past their juvenile stage. Only the strongest and healthiest fry will grow large and old enough to be transferred to the main aquarium or to a different enclosure entirely.

Telescope goldfishBe sure to acclimate your juvenile Telescope Goldfish before transferring them to the main tank or to a new enclosure. Gently introduce them to their new home and be sure to keep an eye on them for a few days to ascertain that they are adapting well and are capable of overcoming the stress that comes with changing aquariums.
