So after you all pointed out that my problem with the aggressive females was probably the tank size, I purchased a 10gal today, along with a couple more silk plants for hiding! Hopefully this round goes better!!!!
Here's the tank:
Here's my CT girl, Medusa (the flash caught her green really well, but in person, depending on the light and the angle, she can be either green, blue, or purply/pink
Here's my other crowntail female, sadly she's without a name...as are the rest of the girls in this post, so if guys want to help feel welcome :)
And here are the battle scars on the others
I gave all of the girls salt baths before putting them in the new tank, so hopefully nothing bad developes from their wounds
