My maroon is about 5" long right now. She's a great fish. I also have a perc that I don't have much of an affinity for (in spite of the rave reviews most people give about their personality).
Some things that they say about the maroons are that they are notoriously agressive/nasty fish (she's never shown signs of that) and they tend to dig up the sand bed when they mature (mine definitely does this, local reefer couldn't take it any more in his 30 and had to get rid of her so now I have her in a 120). She's actually bit me a couple of times. Not so much that it hurt or anything, more like hey get out of my space. Just enough to make me jump. I love her and wouldn't trade her for the world though. Tons of personality. The perc I could take or leave, FWIW
though I think I'm in the minority there. He was the male in a mated pair and I lost the Fem early on. He just never got over it.
Good luck deciding!
