Healthy Cory Eggs

Hi Timmy

Have your panda's layed you some eggs?? If so, congrats.

Here is a pic of eggs, freshly laid from my bronze cories, just before we rehomed them. I got quite a few fry from those eggs, having scraped them off just after taking the pic. The small white bits are sand, she lay on the bottom before finally laying on the glass.

Hope this helps.

;)
 
Yeah, that helps thanks.

Well, not sure if it's the Panda's, Bronze, Peppered or Albino! I put them all in a breeding tank and let them have a free-for-all!
Thing is, on some of the eggs - ones have little black dots in the middle, ones have little white dots and some don't have any dot's at all! I've currently got two air-stones on the eggs and will be removing the adults tonight. Also, got my brine shrimp hatching by tommorow.

Congratulations on the eggs!

The ones with the little black dots are fertile and that is the fry starting to grow. The ones with little white dots and the ones that are just white are probably not fertile. Keep an eye on them because if they are not fertile, then they will fungus and that can spread to the other eggs. Fertile eggs will turn a yellowish brown color too as they develop. You need to get the adults out ASAP, especially the peppered cories, if you want to save the eggs. Im suprised they have lasted this long.

Good Luck :good:
 
Well, I think they have survived because i've had two airstones directly below the eggs, so the adults couldn't get near them because of the flow! I've just taken the adults out and prepared my little nursery! I've also taken the filter out for the time being (will be run in seperate tank until fry are older).
I think the eggs were laid yesterday afternoon sometime, so when should they hatch? Should I turn the airstone off soon to stop the new-borns being launched around the tank in the flow? How big are the fry when their born (easy to spot??) Would it make sense that there are about 40 eggs and only a few have black dots? So many questions... lol!

Thanks for your help.

The fry will take 3-4 days to hatch. The airstone will need to stay in the tank to provide oxygen for the fry, since you have removed the filter. Remember to do daily water changes and keep the tank clean. If they are the only thing in the tank, then you might be able to see them. If the tank is barebottomed (which is better for the fry at first because its easier to keep clean) then you will be able to see them a lot easier. Its not uncommon for a lot of the eggs to not be fertile, espeically if there arent very many males in the tank to fertilze them.
 
Well, there was a total of 9 Corydoras in there in total (of various breeds) - so i'm hoping for plenty of males... not too many eggs though considering the amount of Corydoras in there!

The tank has a sand substrate (with 1 or 2 patchs of fine, flat gravel), a couple of fake plants and a few live plants and also a piece of slate (plenty of cover in the tank meaning i'll have to look hard to see them!) (doesn't help with a convex glass - damm designers!)
I'll leave them for a couple of days them (gives the brine shrimp a chance to hatch properly). I'll keep the airstone running in there then and will do water changes everyday until their big enough for the filter to go back in. The fry must be tiny to fit into one of those eggs!

Thanks again - fingers crossed!
 
I'm getting fungus on some of the eggs, but I can't remove the affected eggs because there in the healthy egg patch! - Hope that makes sense! There are still quite a few eggs with a black spot in them which is good and they should hatch any time soon - i'm hoping by tommorow night (they laid thursday night/friday morning).

Most of the eggs are covered in fungus today even though there's been an airstone running on them :(

EDIT - Water Quality perfect by the way.

Sorry to hear that. Thats why I was telling you its very important to remove the unfertlized eggs. That fungus will spread to the other eggs very quickly. Dont worry about it, Im sure they will spawn again for you soon and this time you will be better prepared.
 
timmystood said:
Yeah but there wasn't anyway for me to remove the fungus eggs. They were all mixed together.

After about 8 hours, the eggs firm up enough to where you can move them. You still to be very careful though. I understand about not being able to move them. Next time, you might just want to risk it, because once that fungus starts, its hard to stop it.
 
Like he said, it is easier to control the hatching environment if you move the eggs.
I move the eggs first thing in the morning when I get the eggs from my Panda Corys. They lay eggs at the night before and it is hard enough to move in the morning. And put them in the smaller container with airtube(airstone) and let it float on the one of the tank so temperature is right. Also this prevent from other fish eat the eggs. I almost never use the fungacide since the agitation from the air bubbles discourage the fungus to form on the eggs but you could since the eggs in the container.
Since Panda is small spawner, I usually get less than 20 at a time. So it make more sense to move the eggs. But if your Cory is big spawner and get 100's of eggs, move other fish to another tank maybe easier. Of course, it is up to you. Good luck and happy egg hunting. :good:
