Goldfish breeding?
« on: September 19, 2010, 07:39:43 PM »

Okay all I am wondering if any of you here have had successful goldfish breeding strategies; what works, what doesn't, what's myth, what's legitimate. I am thinking about possibly breeding them next spring - any advise or comments?

I haven't seriously tried breeding goldies myself, but I do know a lot about it in theory Smiley

There are several different ways to breed goldfish, for example you could hand breed them, but that takes experience or you may hurt the female and give her "cracked" ovaries (in the lack of a better word). So for you, I'd suggest trying to spawn them in your pond! Smiley Introduce a pair in the warmer part of the spring, before the summer heat, the change in temperature might trigger spawning behavior. Feed them a lot of live foods whenever you can, and hope for the best Cheesy After you've noticed eggs being laid, it might be good to take the parents away from the pond and let the fry develop in peace. The parents might otherwise eat all the eggs.

Another way would be setting up a breeding tank, just be sure that the filtration is gentle, a simple sponge filter will do, you could even put it together yourself! Smiley An airstone will be needed too, the circulation in the tank needs to be good, otherwise the eggs might catch fungus. You could easily make a spawning mop for that purpose! Take some green yarn and wrap it around a book, then cut off one end and tie the other. It should look much like a mop c: Tie some cork to the tied end so that it'll float on it's own! The goldfish need to be prepared with live foods and warmer temperatures again, and then introduce a pair into the tank Smiley They should lay eggs on the mop at some point, so take away both the fish when you're certain that the eggs have been fertilized Cheesy

Goldfish lay their eggs at the break of dawn usually, so it's good to be waking up earlier for a few days to be sure that you'll catch the eggs before they get eaten Smiley If you want to, you could keep the female separated for a couple of days after they've laid eggs so that she can rest up. Remember to feed the fry the first time after the yolk sac has been absorbed! Before that, they don't even have mouths, so it'd be a waste to try to feed them with anything c:

That's pretty much it, hope you'll get some goldfish babies! Cheesy

Thank you for all the details! I had always wondered. I'm just wondering what to do if my goldies spawn outdoors next spring. So you can put yarn in the tank for spawning mops? Should you boil it or something first to destroy any nastyness?

It should be enough just washing it under warm, running water Smiley But if you want to, you could boil it d: Guess it won't make that much of a difference Smiley

Goldfish don't really need much help in breeding/spawning but raising the fry can be a challenge.
They need to be fed quite often on powder or liquid fry food or live microscopic foods the first few weeks.
The only time I have raised babies successfully was in my larger pond outdoors in the spring.
Nossie is right that to spawn and raise babies you would need some gentle filtration like a sponge filter, otherwise the new fry will get sucked up by a stronger filter and blown around the tank by the stronger aeration. Smiley
