Well yes you need a male goldfish and a female goldfish to have babies but it takes allot of time to breed them.
Your goldfish isn't pregnant, its just becoming full of unfertilized eggs. Truthfully you shouldn't worry about it, unless you have a male around who is ready to spawn, the female will just lay her unfertilized eggs and then eat them.
Female goldfish are usually bigger than male goldfish.
Goldfish do not get pregnant, but rather they produce eggs. If there is no male around, most often the female will reabsorb the eggs and never actually release any.A female goldfish may get much rounder when full of eggs, but this can be difficult to tell if you have a Ryukin or a Fantail as their body shape is quite round.
my fish also does that. Is your fish a male or female? If it is a female it is probably pregnant. Hope that helps!
Some goldfish are male, while others are female.
Usually a female goldfish mates with a male goldfish!
Fancy goldfish can be male or female.
goldfish start out with female and then turn into male!!!!!!
Female goldfish are slightly bigger than males
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!
yes
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?
