I took some new pictures. I know little to nothing about sexing jags, but it seems like the lighter one is male (top 2 pix) and the darker one if female (bottom 2 pix). The lighter one is starting to get aggressive and, while it looks a lot nicer, I think I'm going to have to put it in its own tank or get rid of it. What do you guys think? My goal was to find a nice jag that was safe with the other fish I have. The darker one isn't the nicest one in terms of looks, but it's the nicest one in terms of personality and personality is more important than looks in this case.
