Dark Vertical Bars

Hi Everyone

I just wanted to ask:

A pair of neon swordtails i have just lately are showing 3 or 4 dark vertical bars on there sides, The female i'm pretty sure is pregnent due to an enlarged gravid spot and a slowly growing tummy. I'm thinking the bars are a "i'm ready to mate" sign , am i right or completely off the mark ?

Thanks

Fish vary in colour depending on their mood and condition. Although the bars do not mean they are ready to mate, it might mean they are in better (or worse) condition that before so have coloured up that little bit more, making the bars more noticeable.
