I'm having a problem with aggressive male mollies in our tank. To cut a lot by story short, we started with 2 mollies and now have 12 females and 8 males. So they've been upgraded to a 240L tank.
Everyone is in the same tank, with a divider to separate them. The males are aware that females are there, so I do wonder if that could be causing it. I've considered making another divider to increase the gap between them. Most of the male mollies go for the biggest one, particularly at feeding time. I'd put it down to the tank size previously but their behaviour hasn't changed with the upgrade sadly. He is also their only target (there is a swordtail and neon tetras). I've included a gif clip
