I am a girl
Biff, I can tell you that in my experience with horses, their cousins, males tend to be hermits and the females tend to be the extroverted types. My guys usually hang out in their "man cave." Could it be that one is a male and the other a female?

It's totally possible Catherine. I have no idea how to sex them. The blue striped is so small (only about 2 inches long) and I read that that species tends to be hiders.
The yellow multibanded is about 6 inches long, and when I have seen those in other people's tanks, they have always been out and about.
So it could be gender, or it could be differences in the species. Or it could be personalities too.
