I currently have (3) 2.5-3" Jags in my 55 and I only want to keep one. The two smaller ones are darker and don't seem really aggressive, but don't really have their own territory, whereas the larger one (in the best shape) has it's little territory and defends it but doesn't really go after the other fish unless they get too close. Which one of these do you think I should keep looks-wise and what sex might they appear to be or is it too early to tell? I'm not sure why the smaller ones are so dark. I have never seen them lighten up, either. The first pic is jag #1 and the 2nd and 3rd pics are Jag #2 on the top and Jag #3 on bottom (the largest one). The last pic is #3.
