Well I picked up 4 Platy and 3 cory today to finish out my 27 g tank. Everything seems to be going fine except that all three of my little guppies are picking on the smallest platy - a Mickey Mouse. I think it's a female. I should have researched male/female better and been sure of what I was getting, but I think I have one male and three females. However, I didn't think the guppies would bother platy. They are just harassing her to no end. Thoughts?
