I'm curious, what is your tank's pecking order like?
In my tank, the list goes like this:
1. Dwarf Gourami(male) - nobody messes with him and he isn't afraid of anyone in the tank
2. Dalmatian Molly(female) - she's actually not agressive, but because of her size, noone picks on her other than the gourami
3. Red Velvet Swordtail(male) - he usually targets the platies(especially the orange one), but always leaves the other two alone
4. Orange Platy(male) - he's really afraid of the swordtail and gourami, not so much the molly, but sometimes goes after the other platy
4. Tri-colour Platy(male) - he's at the bottom because he doesn't pick on anybody, is a little chunky, a little laidback, and usually yields to the others
