So I have a breeding pair of corys in the 5.5. I was getting ready to clean one of the 40 long tanks and what do I see? Momma cory carrying eggs between her pectoral fins. Wow. Moved her to the 5.5. Pretty cool, but I wonder if there is something that is triggering this? Two tanks, same time breeding? Interesting.

Edit: Question--once the eggs are deposited by the female, are they already fertilized?

cory's breed in good conditions, so thats a good sign!

im just wondering, cory's lay eggs on broad leaf plants like java fern (what my albinos did), so are you sure yours doesnt have fungus?

No fungus, very sure. They are laying the eggs not just on the broad leaf plants but also on the heater and some other plastic plants I have in there.

Edit: Just re-read your post. Are you asking about fungus in/on the eggs or in the tank? Both?

Oh, definitely not an illness. The eggs are clearly visible between her pectoral fins. I just checked on her again and they are now deposited on the glass. VERY cool. Of course my wife has the camera today so there is no way to capture this! ARRRGGHHH!!! :c11:

Thanks for all of the positive encouragement! This is very exciting, I've never bred egg layers before. I hope I am able to rear at least some of them to adulthood!

I am such a geek. Going back and forth between college football, AC, and changing out water in the tanks. All excited because my fish laid eggs. So this is what my life has become. (heavy sigh but with a BIG smile).

Very cool. Will the other corys eat the eggs?

Congrats on the eggs!

My cory's have been doing the same thing. She carries them till she finds a suitable place then deposits them. They are all over the tank! I don't want to interupt them by cleaning the tank but i will anyways cause it is due to be cleaned.

I have no idea, guess we'll find out together! I'll keep them very, very well fed just in case.

how long does it take for the eggs to hatch?? couple of days??

3-5 days is what I am reading online from multiple site. Apparently the eggs start out white and get darker as they develop. That is consistent with what I am seeing here.

yeah the darker spot would be the fish.....it is amazing how fast fish can develope and it takes like almost a year for a human to reproduce. lol.

This is a lot of fun. I SO want my wife to come home with the darn camera! I could have had pics of the female cory carrying the eggs between her pectoral fins!

o well.....well i don't have a camera either to take pics of my betta eggs....stupid camera is broken. Also...i wish that i could have a male and female cory...right now i only have one (i am getting some more) and well i want a mixture..male and female.

They will pair off and breed in good conditions. The females are physically larger than are the males.

well then i must have a female because s/he is pretty fat and big.....so i am just guessing...lol. :P

What exactly do your eggs look like right now??

About half the size of a standard BB. Perfectly round. The original eggs are gray-ish, the new ones are pearl white.

Yes the cory's will eat their eggs. Mine have eaten every batch so far. I think it is cause they are new to the egg laying seen!! I hate to go into the tank to remove the eggs as they are laying cause i dont wanna make them stop laying.

During breeding, the males will exhibit a mating dance, touching the female's dorsal. If the female is receptive, the male will vibrate the body to initate spawning.... The female then sucks the sperm out into her mouth from the male's genital pore. At this point the female ejects a batch of eggs which is uniquely held between her ventral fins. And after finding a suitable site, she then spits out the sperm onto the site and attaches the eggs, at which time fertilisation occurs.

This is repeated and may lay up to 200 eggs.... Hatching takes place about 3 days later and may be fed about 3 - 5 days after hatching....
