I got four completely boring new fish today!
I had a white skirt tetra, so I wanted to complete the school and got the rest black skirts.
For what it's worth, the white skirt isn't dyed. I couldn't ever support that.
But they all seemed to be schooling along great. The white skirt is the only female, and she's a bit bossy, but overall it seems they like each other. Even my serpae was welcome to the group, which surprised me.
