Alpha Females?

[DarkPride]

i have 7 females right now, 3 of witch are well acting like males, there just trying to clame leadership over the school i know that, though i have never seen females act like this, 1 of them wants to fight with anyone 1 is bigger then pretty much all my males and the last one is a not too big, and dose not start a fight per say, though she can and will kill very fast, she is much stronger and faster then the other females

any ideas why there like this, i have to keep them in a small breeding tank now after they killed another female, pretty sure for now im going to keep,

hell im pretty sure i might have to also give them the tank im cycling for 1 of my males]

o yea i forgot to say, there in a 30G tank
heated from 76 to 78 depending on room temp,
ph is normal
