Do I Have This Right?

[Dieses Madchen]

I have been reading a lot on here about peoples cories and I have been trying to use that information to sex mine. I think I have 3 males and 1 female as 3 are significantly slimmer, and on is really round and a little darker in color than the others (i do not know if the color matters) Here are the pics of two of them, one is the one I think is female, the other is the one I think would be male.

Possible female:

possible male:

Am I correct?

Hard to tell from the pics,without seing side by side...

have a look here shows a video of my 3 albinos breeding and you can see the size difference between the 2 females & 1 male

I think I have 3 males 1 female. One of mine is definitely noticably rounder than the rest. 3 of mine are really skinny like your male. And then i have one that is pretty chunky.

Sounds good

Mine were triggered by putting them into a separate tank initially, they did go back to the main tank after and carried on
