She looks completely female to me. Her ventral side starts out round and slopes upward towards her tail, characteristic of females. The dorsal is also positioned far back towards her tail, again indicative of a female. Sure she is flaring in pic2, but certain females just do.
Her super long finnage and sharp coloration is just misleading. If you rotate that first picture and look at it in black and white and cover up some of her finnage, her female shape becomes a lot more obvious.
The flaring in picture 2 also covers up her female body shape. The bright white scales make her look flat like a male, but her actual greyish body extends lower (behind her gill flaps).
