It depends on what kind of goldfish; normally, you just have to wait to see who lays the eggs to find out the sex of your fish.
Like goldfish

They look like they are tired but they aren't :)
They are a fancy goldfish (Carassius auratus). They were bred to have scales that look like pearls.
a female goldfish
YES
If you mean like a Siamese fighting fish or beta fish they are like.. size of a ordinary goldfish I think and can be many colors but the fins are long and wavy it's a very elegant fish but still has the intend to kill another fish. But these are only the males. The females brownish maybe goldish. Not as flowy on the fins and looks for like a goldfish. ;)
Shubunkin is just a fancy name given to a specifically coloured Goldfish. Breeding one with a Golden coloured goldfish will result in about 33% that look like a Shubunkin and 33% that look like a Golden coloured goldfish and 33% that look like a mixture of the two. The above results would only be accurate if the breeder fish are properly line bred and their lineage is guaranteed. Otherwise you could get anything from coloured goldfish to uncoloured goldfish and a mixture of any kind of goldfish including Comets, Fantails and Veiltails.
junk
Like a gilbert that's what i named mine!
males have pouches while females don't. the pouches are for carrying the female's eggs.
No. They stay gray their entire life.
