If you also have a male in the tank, it is very likely that she is at the beginning of pregnancy. Keep watching her and the black spot should be getting bigger and she should be getting rounder. This is a live-bearing fish, so make sure there are a lot of plants somewhere in the tank, so the babies can hide from the parents, as they will eat them.
