New Cory Eggs

[Barracuda518]

Anyone know how to feed new born cory fry?

 

[Inchworm]

Yeah, I remember reading they dont need to be feed for the first 24 hours. How do you feed them the liquid fry? When did you add a filter? Right now they are in a bare bottom 10 gallon with an air stone.
I have the 10 gallon filled up almost to the top. Do I need to take some of the water out?

Hi Barracuda518

Congratulations!

To feed the LiquiFry, just add a few drops to the water and swish it around to dissolve it. It will sink to the bottom and sides of the tank where the fry will find it. Microorganisms will also begin to grow on the sides and they will eat them too.

As for taking a little water out, I usually move the air stone up so that the movement it causes stirs the top of the water but doesn't push them around. Because this causes some water to splash out of the tank, I keep the water level down by about an inch.

If you have a submersible heater in the tank, it will be no problem, but if it's a hang on back heater, watch that you don't lower the water enough to cause the heater to react to the temperature of the air.

What do you plan to feed them next?

Hey Inchworm,

I have the tank filled almost to the top. Its about 2" down from the normal water line. Is this ok? Im not sure what to feed them. I dont know if I can find live food anywhere. When do I need to ad a filter?

There are 13 fry now, they keep showing up. I think thats all of them, all the eggs are gone.

Hi Barracuda518

You did well for your first attempt! I'm sure you will be getting more eggs soon too.

Don't worry about adding a filter for 3 or 4 weeks, at the earliest. Until then you will be doing lots of water changes to keep the uneaten food under control and this will eliminate the need to have a cycled tank.

Right now you should think about getting a microworm culture started to feed them between now and the time they can eat chopped up worms and spirulina discs and Hikari wafers. If you don't have them, you will have to raise them on flakes, and this is not as nutritious as live food. As a result they will grow much more slowly and the risk of loss will be greater.

Here's the link where you can read about them and order them too. Or, you can find them for sale on AquaBid.

ok sounds good. The only thing im worried about is having too much water in the tank. I have probably 8 gallons in a 10 gallon tank. Is this ok? The fry are so small and they sit on the bottom on the tank around the edges in 2 groups. You can see thier little eyes and front fins as they swim. Very cool looking

Hi Barracuda518

That much water is fine. They are still just tiny babies and won't be very active for a few days, but wait and see how fast they grow once they start eating.

Inchworm,

I put some liquid fry in the tank and turned the light on. I found 3 more fry. That brings the total to 16. They keep coming out of no where

Do all your cories spawn like this? If so, I dont know how you can keep up with all of them

Goodluck raising them!
Try looking in the edges and corners for the fry, mine were hiding there non-stop for the first two days but then they just all sat on the floor zooming around every now and then.
Just a quick question for inchworm
Are there any other kind of worms or live food i could feed the fry as i can't get hold of blackworm anywhere here. livefoods readily available at my LFS are Daphina, Bloodworm and BS but they are all adult size are any of these good to use yet if i chopped them up?

Yeah, thats how mine are. They stay in groups around the edges and move every once and a while. I have one thats already exploring everything. It zooms all over the tank and up to the top and tries to jump out of the tank. B)

Hi Siamese Fighter05

Your fry are still pretty tiny to be trying to chop live food for them, but when they are ready, you might want to try giving them the bloodworms. I never tried daphnia or live bloodworms since they are not available where I live, but I understand that the brine shrimp lose much of their nutrition once they are adults.

Frozen bloodworms could be given too, and it's easy to shave tiny bits off the frozen block.

Once you start feeding them any of these, you might have to do more extensive water changes to keep the tank clean. Newly hatched brine shrimp and especially microworms have the advantage of staying alive for a time so the fry have a chance to eat them before they begin to deteriorate. Not so with food that is already dead when it enters the tank.

So, do I feed them the chopped up hikari wafers now or do I need to be feeding them the live stuff? Im a bit confused.

 

[Inchworm]

Hi Barracuda518

You won't have to feed them wafers until they are 3 or 4 weeks old. They will be quite a bit bigger then than they are now, and will be better able to eat them.

Microworms aren't actually worms. They are a kind of nematode that is very, very tiny. When you put them into the tank it looks like dust particles floating down. The advantage of feeding them to the fry is that, since they will stay alive for a time in the water, you can provide a constant supply of nutritious food for the babies. They will be able to eat whenever they want and as much as they want. Since their stomachs are so little at first, this insures that they will always be well fed and growing as fast as possible.

Inchworm,

Do Albino C. Aeneus fry have black eyes when they are born? All mine have black eyes. I know the bronze probably have black eyes when they are hatched, but im not sure about the Albino. If 2 bronze C. Aeneus spawn, do you get albinos or does it have to be 2 albino C. Aeneus that spawn to get albinos? Im hoping I have C. Leucomelas fry since they are harder to find around here. This cory thing has got me interested. I didnt realize how complex Corydoras are Lots to learn

 

[Inchworm]

Hi Barracuda518

It sounds to me like you have bronze cory fry. Chances are that only one female spawned, and unless the others have spawned before, it was the bronze. They tend to spawn readily and at a younger age than the albinos, at least in my experience.

The C. Leucomelas, especially if they have been wild caught, are going to be something of a challenge. You might want to do a search to see if they have been bred successfully in home aquariums. If so, please share the information with us.

 

[Barracuda518]

Inchworm,

I went to that link and learned how to grow the microworms. Where did you get your starter kit? I wonder if you can buy them at a LFS. Is this process messy? I guess ill give it a try if I can find a starter kit somewhere locally. Do I have enough time to grow some worms? I dont wont my fry to starve. Anything else I could feed them in the time being?

Thanks
