Finally! Some cory eggs!

I've been trying to breed my corys for the past 9 months with no success. Went back to my college for alumni weekend this weekend aaaand came back to eggs. Yes! I'm keeping them in the same tank, but in one of those 3-way breeder container things. Do I need to attach the eggs to the walls of it, or is it OK to just let them hang out on the bottom?

Funny you should say that...I just finished scraping up a batch of cory eggs myself. I think they'll be ok laying on the bottom of the breeder. I can't say for sure but I believe you described one of the solid plastic types with vent holes in various places.

I use a net breeder with my idea that there's better circulation with the mesh. I've raised a few batches of them in the net breeder and have a small herd left even after giving away a bunch of them. I place moss from the shrimp tank in the breeder box so hopefully they'll get some stuff to munch on while they're growing up. I also feed them the Hikari First Bites.

What type of cories? Mine are just the plain bronzes, but they're a lot of fun.

I put my Cory sterbai eggs in an extra 5 gallon tank. It doesn't matter if they are on the bottom, walls or floating on plants. I have cherry shrimp in there too. The eggs are hard so they can't eat them but they still try. That keeps the eggs clean and they won't fungus. The eggs will hatch in about 4 days and they will live off their yolk sacks for the first 2 days. I feed mine micro worms and decap brine shrimp. I always do a 50% water change every day.

Resurrecting. I had no success with having the eggs hatch. They all got attacked by fungus, even though I tried to dose Pimafix. My corys just laid eggs again a few hours back, so I'm going to transfer them to a gallon water jug and try using malachite green and see what results I get with that. I have to go with malachite green instead of blue because the stores I went looking in didn't have anything with blue in it. The product I'll be using is your typical Ich medication (QuICK Cure in this case).

I also found an interesting article about malachite green and its fungicidal effects on fish/fish eggs after doing a quick Google search.
For those interested:

Bandit - they're albino corys. Most likely C. Aeneus (bought em at Petco last year). Any luck with your batch?

Indeed I did, I didn't scrape all that many out of the 75, just the ones I could reasonably reach. There's a small "herd" of cories in the breeder net now.

Be sure to have plenty of current around the eggs to help prevent fungus as well. I use a hang-on breeder that uses an air pump that has worked very well for me.
