From personal experience I can only relate about my own pair of Maroons and from what I've read on various forums over the past few years, mine are quite tolerant. I think it really boils down to the luck of the draw, not whether the fish you get are wild caught or tank bred. I also reckon their behaviour is influenced by whether they are juveniles or mature fish when introduced to your tank. Some will draw blood & never let you get anywhere near their territory. The only time my female goes ballistic is when she sees the toothbrush. Other than that, my hand & other tank inhabitants can loiter around quite close to the pair's territory, even when there's a clutch of eggs.
I purchased my first Maroon as a juvenile & added a second juvi only a few months later. No idea whether either of them was tank bred or wild. The pairing process was painful to watch & could have well gone bad, but I lucked out and they're now a spawning couple.
I see that yours are small. Any idea if they are a pair yet? If not, there could be some fighting soon as they establish who becomes the dominant female. Once that's decided, you'll find that the dominant fish will put on an amazing growth spurt. After mine got sorted out, the female doubled in size in a month. She's currently at least 3 times the size of the male.
