Picked up a pair of GBR's and was wondering if anyone else can confirm the sex of them. I did spend some time taking a look at both of them and think I have both a male and female. The supposed female holds the back of the tank and they both seem to get into a "fight" when they see each other. Not sure if it is now 2 males behaving that way.
There's one picture of the male and the rest female
