Goldfish can live a very long time provided that you take proper care of them.
One goldfish needs a 20 gallon aquarium with a filter on it's own, and then it's another 10 gallons for every additional goldfish you want to add (so 3 goldfish means at minimum a 40 gallon aquarium).
Along with regular weekly maintenance that includes changing at least 50% of the water, goldfish can live for a very long time.
An Oranda goldfish can have a life span of 10 years if treated right
Orandas commonly get to 10 inches but can grow larger than that.
I believe Cleo was supposed to be an Oranda goldfish. she was large, social, had beautiful flowing fins that matched the oranda almost perfectly, and she had a bigger head and chubby cheek. Her body was also rounded like the Oranda. She liked to be touched. Orandas also like physical contact. you can look up an Oranda goldfish. She was a goldfish for sure but if I'm going to pin point what type, I'd say by personality and physical appearance that she was an Oranda. They're the most social of all the goldfis.
No. The Oranda goldfish will not die simply from depositing eggs. There must be an underlaying health issue.
Wild Goldfish are found in the Yangtze river, but are very different from the domesticated goldfish. In the wild, goldfish can grow up to five feet long, and are reputed to live for hundreds of years.
I know Tasmania has some very strange rules and regulations banning plant materials but I don't think they have banned fancy goldfish yet. Check with a local pet shop they should be right up to date.
A fully grown goldfish can weigh up 10lbs (4.5kg) but that is rare. However, it's not unrealistic for a goldfish to be 5lbs (2.25kg)
Any breed of Goldfish can eat it but onlygoldfish.A female goldfish can lay many thousands of eggs every springtime for up to and over 40 years or so. She can also grow to over 20 inches long in this time.
Yes, the rate at which a goldfish grows, and its overall size, is often partially determined by its environment. This is why pond goldfish are considerably larger than aquarium goldfish, and why goldfish that are cramped-up in bowls stay relatively small. If you want your goldfish to grow into large healthy fish you'll buy them a large aquarium or pond to live in.
For househeld goldfish, they generally live 6-8 years
The average number of eggs layed by goldfish during spawning season is about 5,000. Since goldfish are domestic animals it is entirely up to the goldfish to decide how many of those eggs/fry grow into adult goldfish. Most professional goldfish breeds will choose about 50-100 of the best looking fry to grow into adult fish.
A telescope eye goldfish is in the fancy goldfish type, and most fancy golddfish get up to a foot long (with proper care).
The fish needs better living conditions, more water changes and possibly better food. In order for them to be fit and healthy, fancy goldfish need a well set up, planted, filtered, properly lit, "balanced aquarium". You need to set up for the future with goldfish. If you assume the fish will grow to around 10 inches long, that single fish will need a minimum of 10 gallons of water to live in. Allowing for approximately 1 inch at the top without water (tanks are never filled to the brim) and the couple of inches of gravel at the bottom for the plants to grow in, that single Oranda will need at least a 13 gallon tank. It will also need at least 50% of its water replaced each week. If you have 2 goldfish then you would have to double the tank size. As far as diet is concerned, commercial goldfish foods are usually OK but if you really want your fish to be 'glowing' with health you will include some live food such as 'Earth worms' at least once weekly.
