CoryFan said:Her gravid spots look black in pic 3, which means she is pregnant. They are visible from behind/beside a guppy. They are where the tail meets the torso, on the lower portion of the body.

CoryFan said:Interesting! That had been my experience. If you have a female who has always given birth following a "black spot" time, does that make it more reliable?
Is there any type of illness that would need to be watched for?
Thanks!
