Breeding

[richchappy]

I have a cory that i think is full of eggs, and i have a few questions...
1) has anyone got a pic of a pregnant cory so i can compair
2) are all eggs that are laid? fetalised or not

3) how long before she lays them?

Here is a pic of Inchworm's Big Mama. But I doubt it does her justice when she is egged up. Big Mama is a C. aeneus/bronze Cory.

A fully developed mama Cory all egged up looks like she will burst! The male will swim around her and nuzzle her as she swims around looking for spots to deposit her eggs. The male/s will rub and be touching her as they swim around her, rubbing on her.

ye i am pretty sure my bronze cory is pregnant, i have 3 other corys in my tank, 1 more bronze and 2 albinos so does it mean one is male

The female C aeneus, both the albino and the bronze, are fat mamas and get very broad across the tummy and white tummies. The males are slim little guys. At maturity they are half the size--real little dandies. When they spawn they will do as I said. But if they are with other fish the eggs will have to be removed to survive. To stimulate spawning, feed with blood worm or some other meaty treat. They will respond as though times are lush. Do a large water change. Let the water be just slightly cooler, as though flood waters are filling their little river with fresh clean water and lots of food. As the water warms up they will likely spawn. But don't endanger your other fish by making too big a temp change.

Aeneus spawn readily and it won't take much for them to reward you.

alright thanks for the info, i will give it a try, is there a chance of a couple surviving if you leave it to nature as i have no breeding net, but one is on my xmas list

Mines getting there, and they're starting to do their dance. Do I have to condition them with live foods?

 

[jollysue]

They will love you for it! They probably need some extra protein. The good food also cues them to respond as if it is a good time to bring up a family.

I have 1 or 3 survive from a spawn of a hundred or more. After a few days I start to sprinkle a little fry powder in. A mature tank with some plants will have some other edibles floating around, and if there are no preditors a few may survive.
