It ranges. They generally grow their whole life. The oldest goldfish lived to be 49 and I believe it was about 3 feet....The house hold goldfish lives between 10-20 (20 means you did great!) years and get about a foot long. They seem small as babies but rapidly grow and need large tanks. Small tanks and bowls stunt their growth and causes many problems besides how big they get. So to answer your question, they get big.
Yes
they often fall or have a disturbing chase
Predatory fish and birds will kill heaps in the wild but most goldfish are killed by people who don't look after them properly.
go to the vet ASAP
They've not got muscles to keep them up straight. Its only the water which is holding them up and making them move.
to cure these problems, you should go to your local pet shop, tell them about the problem and the will give you special treatment
Goldfish are cold water fish while the others are tropical, so no they won't as depending on what type of tank you put them in, one group will die.

It's your shoe size in the United Kingdom.Because the United States uses the older, outdated imperial system, while the United Kingdom uses the modern, updated metric system, the measurements are different.UK and US shoe size comparisons:UK Size 2 = US Size 4.5UK Size 2.5 = US Size 5UK Size 3 = US Size 5.5UK Size 3.5 = US Size 6UK Size 4 = US Size 6.5UK Size 4.5 = US Size 7UK Size 5 = US Size 7.5UK Size 5.5 = US Size 8UK Size 6 = US Size 8.5UK Size 6.5 = US Size 9UK Size 7 = US Size 9.5UK Size 7.5 = US Size 10UK Size 8 = US Size 10.5
well im from the US and I'm a size 0 here and would be a size 4 in the UK. that means that: US Size 2 = UK Size 6 US Size 4 = UK Size 8 US Size 6 = UK Size 10 US Size 8 = UK Size 12 US Size 10 = UK Size 14 US Size 12 = UK Size 16 - so a UK size 8 would make you a us size 4! ~beelover
European shoe size for Men = size 40 UK size 7 European shoe size for Ladies = size 40.5 UK size 7
If by "Large" you mean sticking out like telescopes some varieties of goldfish do have that characteristic. If on the other hand it is due to some kind of swelling behind the eye then you have a bad water problem. That would also account for a whiteish film covering the eye(s). My advice is to do more and larger water changes and remember the basic rule of 1" of fish needs 1 gallon of water. If you are overstocked, your fish will continue to have health problems.
