Well, the shy female I refered to in earlier posts is dead. I found her tonight sticking to the filter intake. When I disposed of her, I couldn't help but notice that her tail fin was completely gone.
I have no proof, but I am wondering if the evidence is not stacking up against the mean female. Down to her and three males now.
I will get the black paper tomorrow after work. If I find another dead tetra tomorrow, she might join him.
Who am I kidding, I'll just give her back to Petco...I'm too much of a softie to kill a fish.
I swear I have the worst luck with Petco fish.
