Breeding Questions

[Dieses Madchen]

Hi SELINA,

When in their natural environment, corys swim by the hundreds, I have also had success with keeping just 2 or 3 of them in a tank. In some cases, especially when it comes to the more unusual ones, it's just not always possible to purchase larger groups.

What advice would you have for someone trying to breed cories? My albinos have spawned numerous times. I have saved many eggs, and they all get fuzzy. The one that actually hatched, the fry got a fungus...I would really like more cories (preferable my own homegrown) Any advice? (if you want, send me a PM , i dont want to hijack the photothread )

Hi Dieses Madchen,

Since your question is a whole problem in itself, I'll move it out of this topic and give it a thread of its own.

Briefly, a fuzzy egg usually means that it is either infertile or it has been damaged when it was moved. If it's infertile, it could well be because of the male(s). If you think this might be the problem, try adding some more of them.

To avoid egg damage, try setting up a breeding/grow out tank and letting the corys spawn in it. Then, just move the adults back out leaving the eggs undisturbed.

Corys usually spawn in big (or frequent small) batches. This is because so many of them will not make it to adulthood. The odds against any single one growing up are very great.

Cleanliness, plenty of good food, and frequent water changes are essential to raise cory fry.

I hope you have better luck with your future spawns.

Thank you for the information. The past few spawns unfortunatly happened right before i was leaving for work. Is the anything I chould be adding to the water to prevent fungus?

As for males, I have 4 males to three females, should I add more?

A good water flow with air helps to, to prevent fungul problems.

Greetings. There are many things that you can use to help prevent fungus on your Cory eggs.

1. Methylene Blue

2. Alder Cones

3. Indian Almond leaves.

4. Acraflavine.

Personally, for the most part, I have been using the Indian Almond leaves.

A Google search will supply you with information on all of these additives.

Additionally, as mentioned, polished water and strong current is the first line of defense against eggs developing fungus.

Cheers. - Frank
