Telescope Goldfish (Carassius auratus auratus)

Telescope Goldfish are very friendly and thrive in a community aquarium with other Goldfish. Not only do they make excellent community fish, but they are also super scavengers. However, these Goldfish are not recommended for beginner aquarists. This isn't because they lack general hardiness but because of their highly telescopic eyes. Unfortunately, their eyes can cause them to have poor vision, so they are not a good contender for food. Their eyes are also subject to infection and injury.

These Goldfish will flourish when housed with the other similarly handicapped fish such as the Black Moor and the less hardy Goldfish such as the Lionhead Goldfish, the Celestial Goldfish and the Bubble Eye Goldfish. However, Telescope Goldfish will not do well with fast, competitive tankmates when it comes to feeding.

These fish are very undemanding in terms of temperature and water quality, and they can do well in an aquarium or a pond if the environment is protected, well maintained, and their tankmates are not competitive.

A lot of people will have Goldfish in an aquarium with no heater or filtration. Still, the best thing for your fish would be to provide them with the same filtration, especially biological filtration, that other aquarium inhabitants enjoy. Also, it would be best if you were careful when netting these fish, as their eyes are easily damaged.

Telescope Goldfish are one of the more rounded fancy Goldfish. They are very similar to the Fantail Goldfish except for their slightly smaller size and telescoping eyes. Their bodies are short and stubby with an extensive head and a split caudal fin that is average in length and slightly forked. You can also find these Goldfish with long flowing fins and other tail fin styles such as broadtail, veil tail and butterfly tail.

The Telescope Goldfish is available in various colours in both metallic and nacreous scale types but rarely in a matte scale type. These variations include solids of blue, chocolate, red, white, calico and tri-coloured, as well as bi-coloured versions in red and white and black and white. The bi-coloured black and white version is known as the Panda Telescope Goldfish, with one unique chocolate version that has orange pompoms.

In the home aquarium, the Telescope Goldfish will readily accept most good quality dried foods such as granules, flakes and sinking pellets. These modern food products have been developed to provide all adequate nutrition to maintain your fish's health and dietary requirements.

Providing additional foodstuffs such as live, frozen, and freeze-dried meals such as bloodworm, daphnia, and tubifex once or twice a week will provide additional benefits to your fish's health and well-being but is not a must for this fish.

It should be noted that bloodworms should only be given as an occasional treat and should not be used as the staple diet as they are difficult for fish to digest and can potentially cause blockages.

This fish is an omnivore in the wild, meaning it will consume some vegetable matter. Although most modern fish foods take this into account and include them in their products, you can still supplement your fish's diet with blanched vegetables such as spinach, broccoli, and zucchini. Ensure you do not overfeed your fish and remove any leftovers the following day.

Sexual Dimorphism

It is very challenging to distinguish male from female Telescope Goldfish when they are young and not in the breeding period. However, the male is typically smaller and slimmer than the female, and when in breeding condition, the males have tubercles on their heads and gill covers, and the females will have thicker stomachs when carrying eggs.
