Hello! Everyone
I am back again after I haven't been here for a little while because of school and work at the same time that make me too busy. I really NEED HELP. I have been bred some Corydoras Duplicareus WILD and some Corydoras Sterbai WILD after I did post and asked someone for help a couple months ago. I got some fries from Cory Duplicareus WILD and Cory Sterbai WILD from hatching, but I have some BIG PROBLEMS again about foods when I feed them. I don't really want to loose any of them anymore. I have been bred fries after they have been hatched from eggs. I feed them morning and night everyday with some tiny and some very small bottom foods to fries, and they are growing very fast. I am really happy when I see them keep growing bigger and bigger everyday, but ONE IMPORTANT THING IS THEY KEEP DYING AND DYING EVERYDAY LITTLE BY LITTLE WHEN I CHANGE SOME WATER. At first time, I thought because of me. I am still new for breeding all Corydoras, but I did figure out a month ago, and I don't really want to let all my fries keep dying and dying every single day anymore, so I REALLY NEED HELP VERY MUCH. My fries have been died every single day because of all the bottom fish foods that I feed them. My fish foods have fungus, so fries eat foods that have fungus that make them die. I know it is hard to explain, and my English is not perfect, but I am trying to explain to make everyone understand. Ok! all my fries foods have fungus after I feed fries. I don't put too much foods as well, but it might have some left over after they cannot finish eating. And, they become fungus, and fries eat them, so they've been dead becuase of this after since. I don't know what I have to do, so I post in here for HELP. I think that it might be about of my soft water, and I also put some black water that have some vitamins for them or something else. Is anyone know about this? I am trying to stop growing fungus on my fish foods after I put foods in the water to feed them. This case has never happened to me before because I also breed some cichlids, and I feed cichlids fries the same way as Corydoras fries. And, this fungus on the fish foods never grow up in my cichlids fries tanks, but it happens to my Corydoras fries tanks everyday. PLEASE! HELP. I REALLY NEED HELP. I hope everyone understand my English, but if not. I will explain again the next post more clear.
Oh! first time when I put cory fries in a small tank with sponge filter, and leave barely bottom with nothing only sponge filter in the tank, and fungus grow up on my fries foods, and 've made my cory fries have been dead every single day. And, I heard from somewhere that if I put some sand on the bottom of the tank, it will help stop growing fungus on the fries foods, but it still happen. Can someone help? Thank you very much. I used the same way with my cichlids fries when I feed them, but have never had any fungus on the foods, but it happens to my cory fries, so I don't really know what I have to do.

If I understand your question... which I should because of the repetition , then all you have to do is add an anti fungal to the water. Methylene blue should do the trick. I never had the problem with my paleatus. Remove the uneaten food and add methylene blue and your fry should be fine. Oh yeah... add an air stone so that there is sufficient water movement. Water movement will keep the fungus from forming on eggs, fry, or food.
Good luck

Firstly you are feeding to much food at a time.

First.
I would put a very thin layer of fine play pit sand on the bottom of the fry tank.

Second.
Make a water change of about 30% every day, preferably before a feeding.

Third.
Add a mature sponge filter to the tank it there is not one already. (Fry will graze on the surface).

Forth.
Only feed as much food as the fry can consume in ten minutes.

Fifth.
If you have not already got any, get yourself some Micro worm, or better still "Banana worm". This will give you a constant supply of live foods for your fry.

Hope this helps

Definitely sounds like you are over feeding prepared foods and the uneaten foods quickly fungus as well as pollute the fry tanks' water.

My personal experience with Corydoras duplicareous is that they are not the easiest of Corydoras to raise and losses can be high even with good care.

Neither Corydoras duplicareous or Corydoras sterbai are comparable to raising Corydoras paleatus. C. paleatus are difficult to kill no matter what you do. The same can not be said of duplicareous and sterbai larvae. I raised about 1000 C. sterbai last year but that was only a fraction of the number of eggs I started out with.

I know that apisto... I bought 6 young sterbai a few weeks ago and I'll probably buy 6 more. I'll see how hard they are when it comes time for them to spawn.

I don't mean to hijack the thread but, what are banana eels? This is the first time I've heard the term and am curious about where they fit in the worm hierarchy in terms of size, ease of propagation, etc.
