Passer angels are extremely terrtorial and have a hard time sharing a tank with other angels.As it growns it will want to be the only angel in the tank,you might want to re-consider having it or having the queen.If the passer was the smallest angel you would be fine.Trade him for a smaller one.
Well,removing him from the display might make it mellow down for a few days,the main issue is taht it's the bigger specimen thus it will harrass anything smaller than itself.
