i was having a close look at my angels tonight. when viewed directly front on there appears to be a subtle but noticeable difference in body thickness.
i am fairly confident that my marbel angel is the female, partly as she seemed to be showing a breeding tube the other day after they had laid eggs plus when i look at her front on her lower body is fuller than the black and silver males. a bit like the difference u get in male and female corys when viewed from above. in my angels the male tapers away from mid body to tail where as the female seems to be almost as full and as rounded in her lower body as she does the top.
here is a rough drawing showing what i mean ...
