Hi. Heres another question I want to cover today. My three platies are constantly chasing each other. My male platy is chasing my oher female platy pearl, the 3 month old platy Kara is chasing hyper and pearl is chasing Kara. It's like aggressive chaos in the 10 gallon tank. I'm so glad they aren't aggressive toward the cories nor Gary. Can some help lower down the agression?
