Well my female Fh has been doing some unusual stuff since i got my male Fh and i split the tank in half. i say unusual because she never did this before she has be pulling all the plants popping the top of the water and ramming the divider like she wants to get to the small male on the other side. Also what the male is next to the divider and she is she will flare up showing stress bars and all of her colors the male will flare up also
