Hi
We are interested in breeding our goldfish. We got them around three months ago.
The two fantails and the two moors were aprox. 1 1/2 inches from their fish lips to the tips of their tail fins. They are all aprox double in size now. We also have a shubukin that is aprox. 4 inches. Is there a way to estimate aprox age by size? Can we try breeding this spring? How long after the males show their little bumps is it before spawning will begin? Do you seperate them once you see the bumps?
Sorry for so many little questions, but I've been reading everything I can get my hands on and these are some basic questions that I am still left with. Anybody?
Thanks

Only way for sure is to study a scale under a microscope.

little bumps?? do u mean the ones on there gills, if it is, u can see them without a microscope(if there a boy of corse) and no, u do not seperat the goldfish untill they lay eggs Also, i dont really know how long after they get them, they will start breeding(mine always have them but they get bigger when it comes near breeding time) plus i have no clue on how to tell there age (sorry) I hope this has help u B)
