you look at its bits
Goldfish of both sexes can be happily put together usually without any problems. During the breeding season male fish may chase the female but in general they are very peaceful.
no let it doing
If the fish is male it will be bright and colourful, if it is female it will be quite dull
you dont and you cant.
i want to know how to tell a gender of a goldfish please tell me write back which goldfish is a male and which is a female?
Female goldfish are usually bigger than male goldfish.
It's impossible to know without looking inside of them.
Some goldfish are male, while others are female.
You can certainly try, but most often the comet is not in it's prime until 3 to 4 years old so it may not be successful.
Well yes you need a male goldfish and a female goldfish to have babies but it takes allot of time to breed them.
Females have a protruding anus, while males don't.
they are probably spawning. check out this sight it helped me: http://www.aquariumfish.net/catalog_pages/goldfish_and_koi/breeding_goldfish.htm
