New Cory Eggs

[Barracuda518]

My cories laid some eggs today, and Im not sure which species it is. They laid them on the thermometer, so its easy to remove them. My question is, What do I do with them? I have a spare empty 10 gallon to put them it and an extra air stone. What do I need for the cory tank? Do I need a filter right off, heater, etc. I must hurry because they are in a tank with a bunch of other cories and 3 dojo loaches, and I know dojos love eggs. Ive had to run him off from them several times.

Thanks for the help in advance

Hi Barracuda518

The first thing to do is to get them out of the tank and into another with an airstone set up underneath them. You are lucky in that you can just pick the thermometer out and move it. Don't bother with gravel or sand; a bare bottom tank will be easier to keep clean when you are raising them.

I'd add a heater and keep the temperature around 95 degrees or a bit more, if your tank has been warmer than that. They won't need a filter or a cycled tank at this point, but be certain that the eggs are right in the flow of water from the airstone. They will hatch in about 4 days, so if you haven't given any thought before, now's the time to start thinking about what you will feed them.

If it was your C. aeneus, don't be surprised if they do it again in a week or two!

I got them out of the tank and in the 10 gallon. They are still on the thermometer because Im afraid to take them off. The air stone is directly under them. Im about to go get a heater, since I dont have one in there right now. What should I feed them? I found some more eggs on the back of the filter intake, but I think I will leave them there for now. The eggs are an off white color and I shined a flash light on them and saw little things in the eggs B)

EDIT: Thats 95 degrees F Right?

Hi Barracuda518

You can leave the eggs right on the thermometer and they will be fine. If you want, you can try moving the others too, and if you think they will be eaten by the other fish in the tank, at least they will have a chance.

To do it, wait at least 8 hours after they are spawned. They are very soft at first and the longer you can wait, the safer it is to move them. They will firm up a bit, but still be sticky after 8 hours and there is a possibility that you can gently stick them on the glass in the other tank near the airstone.

Take your finger and roll them off. Then move them to the other tank. It will help if you have a cup of tank water so that you can put your finger (with the eggs on it) into it during the transfer. This will keep them from being exposed to the air for more than the barest minimum of time.

Some people are better at this than others, so take your time and be gentle. You might have good results.

Yes, BTW, I do mean Fahrenheit. Sorry about that. )

You won't have to worry about feeding them for the first day, since they will still be absorbing their yolk sacs, but after that LiquiFry is a good starter food. Then, a few days later, microworms are a good addition, and I understand that baby brine shrimp are good too. The idea is to get them on a high protein diet to get them growing fast. Here's a link that will give you some more information about microworms. I ordered mine from them too. It's not too much work to get a culture going and for the price of a starter portion and a little oatmeal, you can feed many batches of fry.

The tank I pulled them from was 74-76 degrees F. How long do I keep it at 95 degrees F? That seems very warm to me. Guess im just new at this

Hi Barracuda518

OMG!!!! Did I really say 95 degrees?? I meant 75 degrees F. )

I'm really glad you said something.

The temperature of your tank is good for corys, but some people keep their C. aeneus at a lower temperature. I do and like to raise it a little for the eggs and fry. This causes the eggs to hatch a little more quickly and the fry to eat a bit more and grow a little faster than they would at a cooler temperature.

Congrats barracuda!
I am not much of a live food person ) so i have currently reared my first ever batch on liqufry after their first day, then 3 days later i have moved onto frozen BBS which they seem to really enjoy. They are growing well Goodluck with them
Not to hijack the thread or anything but i have a quick question for inchworm or other cory experts. How old do the fry have to be before i can move them onto flake food and pellets?, as long as i mash them up of course? Thanks Dan

Hi Siamese Fighter05

You can move them along to flake and other types of food as soon as they are willing to eat it. Don't even worry about crushing it up. It will soften in the water and, if they will eat it, they will probably be all over it. If not, it will be easier to remove if it is in big pieces.

If you try them on flake food, look for one that has a high protein content, at a good lfs. I use Ocean Nutrition brand Formula One, which has a 55% crude protein content. Hikari sinking wafers are good and so are Wardley's spirulina discs.

Once they are a few weeks old, I move them up to finely chopped blackworms. That always starts them growing up fast. With any frozen or live foods, it's necessary to watch that all are eaten or removed, but you will probably have little problem with that!

I thought that was a little high I checked it this morning and it was around 78. I was very suprised to find the eggs because I didnt do any of the things you do to get them to spawn, just normal water changes every week. Im glad that I have them and am glad to know I have a breeding pair or pairs in the tank. Couple more questions. When do I add the filter? Which filter do you recommend? What about sand? I know Im getting ahead of myself, I just want to be prepared. My C. aeneus are all still quite young and Im suprised to find eggs this soon.

Thanks for all the help, its good to have a cory expert to ask questions to

Thanks. Ask all the questions you want, Im new at this and learning too Ive seen a lot of people with cories on the board lately, which is really cool B)

Congrats to the Daddys!!! Good jobs.

 

[Kopix Nation]

Yea I was kind of woundering what kind of eggs could stand 95 degrees You would roast them at that temperature!!

Congrats to the Daddys!!! Good jobs.

Thanks, They hatched today and so far there are 7 swimming around. Im trying to figure out what to do now. Im new at this

 

[jollysue]

Wow! That was fast! What kind did you say the babies are?

Well, hopefully someone will come to hand hold soon, cause I don't know a thing. B) But good luck. You could review some threads, if you are looking for things to do. Use the search tool at the top.

I think getting some proper baby food is in order though.

Congrats barracuda!
For the first day they will absorb their yolksach so you wont need to feed them. On their second day i fed mine liqufry. I'm surprise you can see 9 on my first day i couldn't even spot one!, now there are at least 70!
Inchworm uses microworm as their first food i think so its up to you.
Once again Congrats and goodluck
Ps: Remeber to clean up all the hatched eggs

I think there are 11 of them now. All of the eggs hatched. They are very small. I think they were in the 55 gallon a while before I found them which is why they hatched so quickly. They are either C. aeneus or C. leucomelas. Im pretty sure they are C. aeneus. I didnt get a lot of eggs this time because the cories are still young, but Inchworm said they would spawn again in 2-3 weeks. I think im going to need a bigger tank if they keep this up

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?

Thanks
