Bipartitus wrasse chasing reflection...normal behavior?

[SwampyBill]

My bipartitus wrasse chases her reflection in a corner of the tank. I've had her almost a year & this has only been going on the last few weeks. Both she & my maleagris leopard are fat, show no signs of ich or other disease, & eat like pigs. Is this normal behavior for wrasse or should I be concerned with some type of intestinal parasite causing this odd behavior? Is another round of Prazipro treatment in order? Or, could it just not have enough swimming room in 65gal tank?

Or might she be going through the change & becoming a male? Sorry for all the questions; I appreciate any & all feedback.

I had a harem of four for over a year, until one day the male and other females went berserk and bullied one into hiding, and I assume it is now dead. For being such wimpy fish they can definitely go aggressive. None of them have been reflection fighters though...

my potter's wrasse does that from time to time.............annoying, but no major issue as of yet. I guess if it's 24-7, I'd have to rework something.........
