Cory Eggs

[Siamese Fighter05]

I was just about to do the weekly water change for the rekord 60 and noticed some eggs. I can only imagine them to be the bronze cories because my one julii (maybe trilli) looks to young. I deffo have a female in the bronze and two males, as i used the method of a fatter one in the LFS. There are about 30 eggs behind the filter and 20 on the opposite side. They are 2'' from the surface. I would like to give them a go rearing but i dont have anything avaible to do it with atm. I have a 2gal platic bowl and the rekord 60 pump which i could face towards the eggs in the 2gal. No heater but my house is warm with the heating on all the time for cold winter. Can i remove them with a credit card into the 2gal. If so do i stick them onto the plastic or on the floor?
I will have no substrate and could do a 50% water change everyday? All the help i could get please inchworm and all you other cory lovers! They are a creamy clear colour if that makes sense, fungus or fertile? they both have water movement over them atm.
Thanks Dan

You need flowing water going over them or they will get fungus, also you can use methylene blue for the eggs, you can move them but you have to be very careful, good luck.

My albino cory eggs were a creamy colour. You cant really see them developing and I thought they were fungused but no
If you remove the eggs I don't think you have to necessarily stick them to anything. I rolled some off with my finger and put them in a net over the tank next to the pump. My favourite way of raising fry

Hi Siamese Fighter05

It does sound like they are cory eggs.

Corys eggs go through changes during the 3-4 days it takes them to hatch. Usually they will start out light and gradually darken, turning from a cream to some shade of brown. If they develop fungus, they will go white and appear fuzzy looking. There will be no doubt in your mind about what has happened. This will usually happen to a few of them and if they are near others, the best thing to do is leave them alone. It does not take long for them to hatch and they probably will before the fungus can spread. If they are fertile and have excellent water circulation over them, they probably will not get fungus. Any that might not have been fertilized will deteriorate and develop fungus. You should expect that there will be some and there is nothing you can do about it.

Other changes the eggs go through is from being soft and sticky to becoming firm. I have often heard that 8 hours after they are laid is the best time to move them, but in my experience the longer they have to firm up, the better chance they have of not being damaged. They are eggs, after all, and are very fragile.

If they have no chance in your tank, you might as well try to save them by moving them into your small bowl. I would suggest if you do want to breed and raise them, you might want to set up a breeding tank of 10 gallons or so and get started right away. If you are feeding them well, especially if their diet has live or frozen worms, you will probably see more eggs within a week or two.

Good luck!

Im going to rear the fry in this tank after all, Im going to get some fry food today. I need to do a water change badly but the eggs are so close to the surface.. can i do a water change and leave them out of the water a few minutes while i put fresh water in? If not what can i do, tank has gone 1week without the change now. I will add another filter for the 22gal for the temporary extra fish.

Hi Siamese Fighter05

It's important that you keep the eggs wet at all times. If they are 2" below the surface, that gives you plenty of room to work. You can take out the water to just above them and that will give you enough room to get in and remove everything, just leaving a bare tank with the airstones and heater running.

I will add another filter for the 22gal for the temporary extra fish.

You can just move the filter that you are running on this tank to your other one. The fry won't need a cycled tank at first.

When you are finished, you can fill it back up. Once they have hatched you can proceed with doing small water changes every day. This helps rid the tank of uneaten food, their waste products, and it helps them grow. In a few weeks you can put in an air driven sponge filter to begin cultivating beneficial bacteria, and by the time they need a cycled tank it will be ready.

Well... How do i put this
Today i have emptied all the water and scraped the eggs off and flushed them down the toilet Sorry but im not prepared for them yet. I am going down the LFS now to go pick up a pump, airstone some foods to condition my cories and try again being fully prepared so i can bring the fry up to the best of my ability. I emptied all the water out and removed the excess sand i couldnt get out yesterday. The tank has been cleaned ive added some fresh declhorinated water to the tank a heater and a pump. It completey bare now. I just need a bit of help on how to prepare the tank if anyone could help? I have some fake plants that i can clump together one end to give the parents some hiding places while i condition. I think that it is everything?
I wil add the fish and their filter tonight when everything has had time to stabilize a little. Ill start condintiong them tomorrow for a week or two on bloodworm and brineshrimp. Anything else i could use. Ill look for blackworms but ive never seen anydown the LFS. Im sure i will have success this time round being fully prepared. Thanks for all your help via PM's inchworm, it will be helpful this time around and im sure i will be harrasing you again soon. Thanks everyone else and keep the help coming! it's more than welcome
Thanks Dan
Off down the LFS now to pick up the bits and bobs.

I hope the poor things dont hatch now they have been flushed!!! I was in the same situation. I fed half off the eggs to the fish as a tasty snack. Bringing up the babies in the same tank too.

Hi Siamese Fighter05

IMHO, you did the right thing and need not feel even a bit bad about it. The next batch will be that much better off for it.

As for them hatching after they have been flushed, Lynz781, that will never happen. Eggs are fragile things and easily destroyed. I'm sure that happened immediately.

Hmmmm my cory eggs were pretty tough. I wonder what makes them stick like that.
