Hi wiccanfishlover

Your C. paleatus eggs and fry shouldn't give you that much trouble. They are quite flexible about their water temperature and conditions. Let's try to figure out what's wrong.

It would help if you tell me a little about your fish and the tank you plan to raise them in. What temperature do you keep it at? Is there sand or gravel or does the tank have a bare bottom? Are you doing anything to change the pH of the water?

I hope this batch hatches and does well for you, but if it doesn't. perhaps we can help you prepare for next time.

well i have them in a 1 gallon for now so they can reach the surface to breathe there is only about 2 inches of water in there with them........bare bottom...... room temperature wich is probably near 70...i added prime because my water contains alot of ammonia,added 2 drops of watersafe and left the ph alone because it came out of my tap at about 6.4 they have allmost all hatched last count was 25 still more to go. Im not even sure when i should feed them......They just hatched this afternoon ANY help you can give me would be wonderfull. there isnt a heater or filter in the tank with them because theres just too little water for it at the moment once they can get up better i will be moving them to my 20 gallon fry tank wich now just has 2 diff species of killi fry in it. Hope this helps if you need more info you can e-mail me @ [email protected]

Hi wiccanfishlover

I'm glad you responded so quickly. There are a few suggestions I can make that might help.

First, they don't need to reach the top to breathe, but they do need oxygen. If you can gradually fill the tank with clean, dechlorinated tap water, it would be a good start. If you can get an airstone just under the surface of the water, and adjust it to just move a little water, that would help too.

Another thing cory fry need is lots of water changes and that will be a big job with such a small tank. They are OK for now, but be prepared; they grow quickly. The biggest problem with cory fry is that they are in danger of bacterial infections. This can be caused by uneaten food, so the more water in the tank, and the more water changes you do, the better their chances of survival are.

Did you mean there is ammonia in your tap water? Or are you using water from your tank? This is not a good thing at all. Please try to find a source of water that is more pure.

If they have hatched in pH 6.4, that will be fine. It's almost always best not to fool around with the pH. A temperature of 70 is fine too, but once they get into a bigger tank, a little warmer temperature will speed up their metabolism and they will eat more and grow faster,

Don't worry about feeding them for at least 24 hours because they are absorbing their yolk sacs and will just be sitting still for a while. Cory fry are slow growers, so don't be in a hurry to move them in with other fish, even though they are small too. For their first few days you might want to give them LiquiFry or something similar. A better food, but one which will take a couple of weeks to culture, is microworms. All fry love them, so it you raise many, it would be worth the effort. If you put your location in your profile, I'll give you a link where you can order them since they are not available at lfs.

Is your tank bare bottomed, or do you have sand or gravel in it?

There are a few members who are raising cory fry right now, so if you look through some of the recent threads in this section of the forum, you will get a lot of information about how they are doing it, and I'm sure they will be posting here to help you too,

Best of luck with your babies!

It is one I started a while back when I got my first batch of eggs and Inchworm walked me through it.

Good Luck
