The red shoulders should last, but they are always getting bullied. I have one very nice male in the peacock colony though. Right now, I have 3 male ruby greens colored up and dang, the dominant has a very dark orange and black to it. He's my favorite and he always shows off. The 2 other males are also very nice too, but not as nice as the dominant. If they were separated, they should be just as nice too. I have to wait till my sister gets back from sac with the camera though. I'll try to get many pics.
