Hi,

I bought a group of young congos and had trouble sexing them but it was because they all turned out to be female!! Aparantly females are more common than males at the LFS. How long have you had your group and how large are they?

That sounds like my situation lol.
I already had 2 males with the large fins, so i bought 4 more congos that where really young figuring id b unlucky not 2 get a couple more males. But now they are nearly 2 inches and no larger fins are showing on any!

Does any1 want any female congos for breeding? lol

You need females to break up the aggression otherwise they will constantly chase, fight and harrass each other

I didnt want an all male shoal just expected out of 5 i would get @ least 2 males, but it looks like they were all female.

Ohh I see, nightmare, I always make sure I watch them pick out males for me and check the bag too, it's hard when they are juvies but still possible to tell the difference under a good light as the males are slightly darker and stronger colours even from shop age

That is good to know I bought 4 small ones that I assumed were females But I notice one has quite a bit more color.I was wondering if it could be a young male.
