I picked up 6 Boesemani's last night. I was very happy to see what I thought were 3 males and 3 females...though they are still small, about 1.5" so a little difficult to sex, I thought that is what I saw. Well very quickly after acclimation the look of them changed, and I now have 5 much more colorfish that for the most part all swim together, and one less colorful fish (certainly less indigo on her) that swim's often lower down by herself. Can this ratio possibly work? I don't want to take any back but I also am not going to have room for 4 more females.
