I would like to add some information!
First, this is a picture of my beautiful female after about 3-4 months in my tank:
The Info: these fish, at least in my experience with this female, can be closet-case aggressive. You wouldn't want to believe it, but I would add a female betta, and it would die on me for no seeming reason. All the time, the only fish that attacked them (visibly) was the krib. My veil angel's fins started to get nipped as well...Since it all seemed to point to her, I had to make the heart-wrenching (trust me, i loved that fish!) decision to remove her from the tank. While she was there 3 female bettas just "died" for no reason. Since then, I have kept 2 females without any troubles. No fins are being nipped. It seems as if most, if not all, of the aggression in the tank left with her
So, just a word of caution. If you introduce a "peaceful" krib into your tank and things begin to go haywire, take a closer look at the krib's behavior!
And to show what i'm talking about...here's a picture of one of my favorite betta's ever that she killed...who's in the background?!?!
