Hello! I just got four GBR. I got two at first, and asked for good looking ones (stupidly, instead of asking for a m/f). Then I thought I HAD a m/f, and went back for another two, and asked for a m/f. All same store and same tank. I believe I got a m/f the second time but the first were two males, so I think I have one female and three males. I that the one labeled # 3 in the pictures is a definite female. It’s hard to tell bc they are round belly and some are long finned. I’m HOPING I have two females and two males but I doubt it. I think numbers 1 2 and 4 are males. The confusing part is that 1, 2, and 4 all have little areas in my 64.8 gallon but the known female is chased out of all the areas and has nipped fins. # 1 has taken the right side, # 2 the middle left and # 4 the far left, both behind large wood. So it’s POSSIBLE 2 and 4 are a mated pair that hide together but they both really look male and I think I see them flare at each other often. Just not sure what happens behind the wood. And I don’t get how # 3, the known female, couldn’t find a mate with three males in the tank! I hope I have two females and two males (and that they pair up) so I don’t have to take any back but I don’t think I do. Again, they are round belly and some are long finned. The only thing I have to go in is that the one known female looks very different and the others look more alike. But then I wonder bc why wouldn’t one of three males pair with the female? How long does pairing up take? Please help!
