Blue Gourami's

[Bonnie]

I have 2 BG's and they've been in the tank since the beginning(2 years). I'm pretty sure I have 2 females, the dorsal fins are alongated back and rounded not pointy. Can they come into breeding mode
even though there isn't a male. They went from being silvery blue to dark blue striped, and just plain acting weird. One is hiding in the petricolas cave(pvc elbow) and the other is haning out in a corner, which is not like them. And they're running away when I approach the tank which is also not like them, they eat from my hand usually. They do look beautiful, just acting strange for them.
