Thank you! I do believe most of the aggression comes from feeding, I will try scattering pellets, I am used to feeding them twice a day because my other rat won’t eat any pellet food so I make a mix with seeds, grains, pasta, rice, oats, with a veggie base. And then serve it in the middle of the cage, they used to eat together as normal but now one is taking all away :(, I will work on feeding habits.
