fertile cory eggs?

[smart]

ok i got home today from work looked at my tank to see approx 300 cory eggs on the glass and plants :woohoo:, i'm assume laid by my bronze corys. only think is never having bred corys myself i'm just not sure if they are fertile, after reading up abit i dont think they are as the centers seem too white :dk:. can someone confirm for me

many thanks

They look to be duds mate, its a shame

cheers steve, looks like a learning curve for me and the corys

yeah im affraid theyre dudds. unless they are freshly laid, and may turn darker. yeah cory eggs turn darker, to almast black when ready to hatch. goodluck mate

was it their first go? often more luck with second attemps.

its their first attempt that i know of, i moved them from my main community tank a week ago. never seen any eggs but its possible they got eaten. although their behavior would indicate they are alot happier in this tank to breed

How many you got Martin?

 

[Irene0100]

they often breed the day after a cool water change.
so watch for the mating ritual the day after your next big change.

i have 3, 1 female, 2 males

i have tried the big w/c a few time before when they were in my main tank, but as i said they seem to be alot happier in this tank and i had done a big w/c at the weekend. so now i know they are ready i'll leave it a while and try again :thumbup:

i'll be knocking up a egg tumbler of sorts so i can be abit more prepared for it for when they succeed

best ratio mate. i rasied my fry in a big lunchbox, floating in the tank. they look like tiny tadpoles when first born. then take shape after some days - weeks.

thanks jack, i've had some experience due to friends that have bred corys. i've got a spare small tank to keep any fry for when the time comes as there is no way i'm breaking down the tank to catch them :lol:

 

[Irene0100]

I dont think you need tumbler for cory eggs (unless very gentle, I just put in normal fry saver net and put net where there is some water movement from filter outflow.)
I remove eggs from glass within hours of laying by gently rolling onto finger tip.

 

[weisel]

or use a stanley blade sideways so u dont break any of the eggs, obviously u can only use this on the glass. if u remember how i used to do mine then u wont loss any.

thanks irene and scott. I've made an egg tumbler and using dud eggs to test how gentle it is. I have an idea about removing the eggs from the glass.
Scott be on standby :lol::lol:

I'm sure you'll have better luck next time, I've heard someone call infertile eggs with the white centre as having the 'arc of doom' which is a good way of telling the bad ones. Shouldn't be long before they spawn again.

Cheers

I use the finger method too. the eggs are surprisingly tough and if they are sticky enough they will stick to your fingers while you roll them off the glass. i have tried the blade method also but was a little heavy handed with it and cut a few eggs in half

 

[smart]

i was going to have a go removing the dud eggs when i got home today, have a practice. but they are all gone now. i think the female removed/ate them, last night when the lights went out there was alot of activity with her. i asume that she was checking them but removed as she knew they were duds

 

[danielryan]

can you leave the eggs in the tank? i only have bronze corys and a few neons in this tank.

would they get eaten?

 

[JackGillett]

Hungry cories will go looking or eggs, especially if they know where they are..
my pandas love to lay them of anubias nana leaves, but only the small ones. i have a coconut cave covered in java moss with an anubias strapped on top. i use my nails to pick the leaf of so the eggs stay clean and off the ground in the fry saver. one thing to note.. in my experience eggs not stuck to something struggle to hatch. the fry hatch tail first, then the head. when removed from an object, when they hatch they struggle to get the egg shell off their heads, like a dog with a bucket Although quite comical, this can prove fatal. My biggest tip of breeding cories, NEVER remove the eggs from what its stuck to. :clap: happy hatching and goodluck

I've had plenty of luck rolling the eggs off the glass/leaves and then I stick them to the side of a container singularly so if one goes bad it doesn't damage the others. My female sterbai will eat eggs as fast as she's laid them, and while other corys may ignore eggs they are far too tempting for most tank mates to leave alone so I do tend to remove any eggs.
