Sexing Corydoras hastatus.

Post by Papja »

Hi!

In species profile I can see that female of this species have brighter coloured eyes. http://www.planetcatfish.com/common/spe ... ies_id=324
It is just issue of the photo, or it can be really a point in sexing them?

I beleive its just the way the flash bounced off the eye- Best to do the usual cory sexing method after they have been well fed for a while, put all the specimens in a small bin with tank water and look at them from above. Males will be smaller when compared to the larger and plumper females.
I can stop keeping catfish whenever I want. I just don't think I'll ever want to do that...

Mine only started to show differences in sex once fed heavily on live foods. They all looked exactly alike, then with addition of live foods the ladies started to swell and started to produce eggs. Once mature, the ladies are round and fat. Males seem to stay slender and much smaller.
