Eggs!

[Amunet]

I just went to feed my fish and I spotted a bunch of eggs on one of the plant leaves. I'm about to go back and check for more, but what should I do? Do corys lay eggs if they're not fertalized?

I'm gonna snip off the leaf that the eggs are on and temp put them into a breeders net.
We have a 5 gallon I need to clean out, but what should I do to prepare it for hopefully some fry? Should the temp be at anything special? Should I leave the filter on?
How long will it take for the eggs to hatch?
I only have liquifry food and that powder first bites stuff... will this be ok? Or should I start trying to get that infurwhatever stuff you get from lettuce leaves?

Here is a pic I took of the leaf after I snipped it off and put it into the net...

I was doing a water change and noticed 2 more leaves that had eggs on them. I snipped one of those off (the one with the most eggs) and left the other which has no more eggs on it now since my betta spotted them.
I'm pretty sure they weren't there before though and not sure if corys lay their eggs when they get full like my danios do... so do you think these new ones would be fertalized?

Hi Amunet,

Congraturation for the eggs. Yeah, they sure look like cory eggs. And judgeing from your tank occupants, I'll take it you have Sterbais. Or do you have another kind of cory in the tank? Also how old is the fish or how long do you have them.

Here is the good link you can read and learn few things about hatching and raising cory frys.

Although it is not always a good batch of eggs(hatch rate can be low) for first batch or 2. As long as you have male and female, some eggs will be fertlized. It may not be this batch but it will. Sometime the male is not matured enough but as the time goes on the hatch rate should improve.
And yes, they do lay some eggs if there are no male and she can't hold eggs any longer. They call it throw off the eggs. I believe the female does it so she won't be eggbound. So there is a possibility that the eggs are not fertlized but judging from the color, it looks good eggs. And if there are a male, it is really uunlikely that he didn't try to fertlize the eggs.
Anyway, keep it seperate from other fish, it is up to you to use some fungucide but it can be tough to use when you are using breeding net. You could use airstone if you have any sothe water circulate and discourage the fungus. Or you could use some container like tupperware and put some fungucide and airstone.
They usually hatch in 3~5 days. It depends on the temperature which cory's egg.,etc.
The article should answer most of your question.

Place your net near the filter outflow so the eggs get some aeration. If they were fertilized they should hatch in 3-5 days. Not sure about the tank. Some sand in the bottom and a sponge filter should work. I don't think you need to totally fill it. I fed mine first bites and had few problems. I put a little tank water in a plastic cup added some first bites; swirled it around some and slowly poured it into the net.

Thanks you 2!
Gonna read that link in just a moment.

We have 2 sterbai and 2 bronze green corys.

I'm pretty sure the 2 sterbai are males, and we have a male and female green, but I'm really not sure.
We've had them all for a few months now and this is the first time we've gotten eggs which is why I'm freaking out a bit b/c I'd love to have baby corys! heh


So right now the leaves are in a breeders net, do you think it would be best if I left it in there until hopefully they hatch and then move them to the 5 gal?
For treating fungus.. would that Jungle Labs Fungus Clear tablets work?
I just put the net into an area where the water flow is better so I'm hoping fungus won't be a problem.

OO this is so exciting! Think I might get another breeders net for the other leaf so if I do get fry it won't be so crowded.

I have another question.... How will I know if the eggs are still ok? I mean besides the obvious (if they hatch or not).
Is there a sign before they should hatch if the eggs are still good or not?

 

[NEONCORY]

Yeah, I was thinking they were not laid in usual Sterbai fashion. That make more sense that they came from the Bronze Corys.
It seems Bronze lay eggs in concentrated area than Sterbai does.

Anyway, good eggs usually color up(get darker but stay pretty clear and you maybe able to see the eyes when it get near the time to hatch. Although it is depends on the species, it vary the degree of darkness). And bad eggs is usually get either fuzzy(if fungus get to it) or more milky white(opaque instead of clearer color).
After a few batch of eggs, you'll know which eggs are good. And you'll know which bad eggs you should remove. I still am not good at throwing eggs because of some hope of hatching but it usually they don't hatch after a week.(of course, it depends on the temperature and species but...they usually don't if you kept them in 75F or so).

 

[Amunet]

Well this batch of eggs are bad. They've gone fuzzy. I'll know how to take care of them when it happens again though so I'm not too bummed about it I'll be more prepared next time it happens

Thanks so much everyone for all of the info!

you can tell right from the get go that they were not fertile by the white dot within the eggs. fertile eggs do not have this dot and are more of a tan color. you can usually see the embryo in the eggs when they are fertile right from the start
