ORANDA: The Oranda is a highly favored fish with many beautiful qualities, and is compatible with other fancy varieties of goldfish. Like many other fancy goldfish varieties, prolonged periods of cold are not advisable for the Oranda. They must not be kept below 55 degrees fahrenheit for long periods of time. The Oranda is one of the larger fancy goldfish varieties growing up to 7 - 8 inches and live for upto 10-12 years. (The maximum as per record book is 20 years)
TELESCOPE: Because their protruding eyes cause poor vision, telescopes should ideally be kept with other fancy goldfish with impaired vision: bubble-eyes, celestial eye, or other telescopes. Sharp gravel and ornaments can damage their eyes, and should not be used. Telescopes are also more susceptible to a condition called "cloudy eye", a bacterial infection resulting from damage or scratching of the cornea.
Like all fancy varieties of goldfish, telescopes require a minimum of 10 gallons of water per fish, with a minimum ideal tank size of at least 55 gallons, and a lot of filtration. As a fish grows, it is sometimes necessary to expand this rule to 3 gallons per inch of fish-body. Tank water must be changed weekly in sufficient amounts to keep nitrate levels below 4ppm. A well kept telescope will grow to 8 - 10 inches in body length and shall live upto 15-20 years. (The maximum as per record book is 32 years)
