My male flowerhorn and female purple rose queen seem to be hitting it off they moved all the rocks out of the middle of the tank and get aggressive if another fish moves in the area. I have 3 well-sized pikes in there another male purple rose queen, two small red devils, a med-sized turquiose jewel, a med uaru, and a large pleco in a 75. If they are breeding what should i move out of the tank so they can have babies?
