no let it doing
Usually it's because the male wants the breed with the female so he chases the female around the tank! So unless you want little fry (baby goldfish) in your tank you should separate them!
The male and female goldfish may be separated for up to a month. During this time, they should both be fed a high quality fish food to prepare them for breeding and to help the female lay healthy eggs. White eggs is a sign of infection, a common malady in goldfish eggs.
they are probably spawning. check out this sight it helped me: http://www.aquariumfish.net/catalog_pages/goldfish_and_koi/breeding_goldfish.htm
a goldfish that is Female
Dont worry about female or male, they may have babies but it does not effect them dying! Just leave them where they are act as normal, by cleaning out the tank! and feeding them.
No
Female goldfish are usually bigger than male goldfish.
Like goldfish
Usually a female goldfish mates with a male goldfish!
Female goldfish are slightly bigger than males
the goldfish that is being chased might be a female goldfish where as the others are male goldfish, so the female one gets battered around the tank and the fins and tail might shred it is a good idea to separate the single fish so it wont be attacked. i know this cause my Goldfish do the same XD Look for white dots on the cheek of fish that r chasing the other one. if it does have white dots its a Male hope that helped :)
goldfish start out with female and then turn into male!!!!!!
