Goldfish breeding help

Anyone have info on breeding goldfish/comets?

At what size is a goldfish ready to breed? I know the signs of maturity and the gill bumps and round belly. Will a 2-3 inch (-/+ 1 year old) goldfish breed?

Here's a pic of my comets I gave away. I hope to get new ones soon.



I entered this photo in the October 2009 contest.....


I really miss the buggers and want to get some fancy tailed goldfish or these comets and start breeding them. These were about 2.5inch in the pic but I gave them away in February this year when they where 3+inch.

I used to feed them on bits of cichlid pellets, bloodworms and earthworms alone! I made sure they where as healthy as seahorses!

I'm sure most users want to know how to select a breeding pair and how to eventually get them to spawn. I'm also sure that there is someone here who has successfully spawned and raised comet/goldfish fry.

Please help

Regards

hi
lupin is your best bet,send a PM and i'm sure you'll get a response.
i bred my commets in my garden pond,i found the female prefered the shallow shelf
where the pond weed was the thickest,and i would sit and watch the comotion,
she spawned,and many of the others would follow to eat the eggs,i was somtimes
able to detract the others while the pair spawned with food,i had fry survive which fed from the
algae from the edge of the pond,and as time went on,i'm sure with all the other goodies
that was in there they began to venture out for the flake and the pellets,many were eaten
buy the larger fish,but the wise ones stayed in the shallows.

wonder if this helps ?
good luck :)

when you set up a new tank,hide an extra
sponge or two behind some decor,that way you have
something seeded for you next filter.

Goldfish are sexually matured when they hit a year of age. Yes, 2-3" ones can spawn when they are sexually matured but it is also a definite sign they are absolutely stunted. Depending on the fancy variant you are dealing with, an average size should be at least 6-8 inches. Orandas, ranchus, lionheads, ryukins, fantails and moors/demekins are notably large at 12" average in length when kept in the right conditions. Singletails average 12-18 inches in length.

I placed my 1 male x oranda and 1 female x sarasa oranda in a breeding setup last night. I woke up this morning to find 30 - 50 eggs all over the tank with only 2 eggs on the spawning mop.

I had them at 28 deg Celsius and then put them in the breeding tank at the same temperature. I then set the heater to 22C and later switched the heater off completely. This was done in a period of 3 hours.

During this time I fed them bloodworms every hour until lights out. I woke up at 8am this morning to find the spawning mop at the other end of the tank. Not where I initially placed it. It took half an hour until I was happy with the chasing but then I added my fan tail male so he could add some interesting features to some of the fry.

He chased her around but she only threw out about 10 - 15 eggs. She still looks plump but after 1 hour, they just sit there looking for food. I removed all the fish and turned my HOB filter (with sponge on intake) and heater on (22deg).

I guess its a bit too late to start an infusoria culture.

Can I just feed them crushed flakes in water after their egg sacks are completely eaten?

I cant wait for them to hatch!It apparently takes 2 days or so....

out of the 50 eggs, I'm guessing that there will be about 25 fry born healthy.

Yay!!!

EDIT: Just placed the male and female back into the breeding tank. I'm not convinced that they are done spawning. She still is a bit plump and needs to lose some egg weight!

Yuck! No flakes for all goldfish. These are not nutritious for them.

Start with green floating algae which you can culture in a jar with a pinch of fish food placed under direct sunlight. You may try hatching baby brine shrimps, even shred homemade gel foods to pieces or suspend a bit of egg yolk from a hardboiled egg in a jar of water and squirt to the fry.

Hatching depends on temperature but average is normally 3 days. After they spawn, please do a water change as the infertile eggs quickly foul the water and can even kill your fish.

My goldfish fry hatched!

They are already free swimming?? I might not have noticed them in the tank because they are so tiny!

I squirted some egg yolk in the tank last night just to be sure they eat something.

How long must I wait before I move them to another tank and feed them a more solid food like mushed up blood worms?

Regards

A month or two will do. Goldfish fry are very sensitive to sudden changes so err on the side of caution and do small water changes daily by at least 10-15% a few minutes after feeding them the egg yolk. They must be fed in small servings several times a day. Provide them plants to munch microorganisms on and keep temp to at least 78 degrees Fahrenheit.

They are in a tank full of hornwort.

A few of the eggs are not hatched yet. I can see the little eyes but still in the egg stage.

I will do a water change now and feed straight after.It's so difficult because I never know if they are eating or not.

Thanks for the advice!
