no they do not, they evolved to the point that with a simple look in the eye from an alpha male goldfish it can inpregnate not only female gold fish but the male gold fish too. this has been caused by centuries of evolution.
No,you need both male and females to have babbies even goldfish.
Usually a female goldfish mates with a male goldfish!
There is no difference
Well it depends. If your msle goldfish shows signs of being a predator. Remoe the fish immediately.
It's impossible to know without looking inside of them.
Well, when goldfish spawn they lay thousands upon thousands of eggs. The male goldfish then sprays a cloud of milt which fertilises the eggs. For a goldfish to only lay one egg which, somehow triggers a male goldfish to release a cloud of milt, is highly unlikely. Truthfully, it is the person breeding the goldfish who chooses how many fish they are willing to raise. Technically, they could choose to only keep 1 goldfish fry but realistically they would not be willing to throw away the lives of so many baby goldfish fry.
Some goldfish are male, while others are female.
Female goldfish are usually bigger than male goldfish.
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.
I think baby goldfish are called fry.
no
you look are the goldfish tal and the female has a bigger V than the male
If your goldfish is female and full of eggs, she may release them in the tank. If there is no male in the tank with her, she may very well simply reabsorb the eggs without ever releasing them at all.
