Pregnant albino corydoras

[mrplaty]

i have three albino corydoras. is there any way of telling if they are pregnant?

how do you tell what sex they are?

what do you have to do when they have laid their eggs?

cheers

You say pregnant, but you know they lay eggs.

Better way to say it: laden with eggs.

You look at the from the top (or when they swim at midlevel across the glass).

The females are wider and the males, slimmer. There might be size differences but that might be misconstrued due to ages...

how do you tell what sex they are?

Females are the rounder and fatter, as Tempestuousfury said, some species show difference in the pelvic fins. The females have rounder, oval shaped fins and the males spear shaped. Males also usually have longer pectoral fin spines than the females.

Hope that helped

The correct way to say it is gravid

Any suggestions on how to breed this type of catfish? And if so, are their certain times of year they spawn, and do they require certain changes in water? This saves me from having to make a Topic..

Hi AllusiveLife

Albino and Bronze C. aeneus corys are easy to breed and will spawn pretty much whenever they want to once they are mature. In their natural habitat, our fall and winter is their spring and summer, so now is the time they are spawning.

Here's a link that has information about the type of breeding setup I use, and some other general information about them:

Once they are mature, they will start laying eggs on the glass. While you might not be prepared for the first batch, another will soon follow, and it will be larger than the first. This often happens after a big water change, especially if the added water was cooler than normal. While this will not harm corys, other fish in a community tank could get ich if the water is too chilled. It's better that you move them into their own tank first.

Often, after conditioning them well on live blackworms for a week or two, I'll just do a good water change in the early evening, and unplug the heater overnight. In the morning I plug it back in and gradually increase the temperature. If they are ready to spawn, they will do it within a few days.

It's best to have one female to two males, if possible, but it's not necessary. With two males you are likely to get a higher proportion of fertilized eggs though.

It's good seeing you post again. Good luck spawning them. There are few things more fun than watching a tankful of baby corys growing up!
