Well a couple of hours ago while i was observing my fish tank i noticed my male platy chasing my female platy that i just bought and put in the tank! He was moving the fin (i think anal fin) towards her area where the poop comes out and it kept hitting her there!! Is this a sign of platy mating!! I remember when my swordtails mated that my male swordtail swam backwards and poked his tail in her belly area!!! *DRUMMER*
