So i added a 3rd wheel, to my 2 parrots, actually saved it from unspected petco people. anyway that was about a week ago and sometimes its still mean, pretty mean. not all the time but when it happens he chases only the other 2 parrots around the tank, not just to there hiding places but in there places then he bullies them out. I really like this parrot's look but i figured his bullying would stop soon. The others dont do anything. since the bullied parrots are pushed into hiding that also starts a fight with one of my parrots and DG. his rule is the plants and he has no problem going against a fish 3 times his size...
