Moving GSM to a bigger tank, can it be less aggressive?

[CzarQwerty]

I bought a gold-striped maroon clown fish at a LFS a few years ago without knowing what I was getting myself into. She is currently in a 20 gallon tank and of course thinks she rules to place.
I'm setting up a 75 gallon tank and I am worried that the GSM will continue to be aggressive to any new tank members I might add to the new tank.
Does anyone have any thoughts or experience with this?
I really like my GSM but I am worried that she'll torture anything I add to the new tank.

I think you will see a change when you place her in the 75. Her territory basically covers the whole 20gl tank, so anything you add must pass her inspection. In the 75, she will still claim a territory, but it shouldn't be the whole tank.

Just something I've noticed with my maroon. She is very calm and gets along well with everyone as long as I feed her every day. If I skip a couple of days, she gets vicious.

If she's being hosted by something, I think she also might be contained a bit, since IME maroons don't tend to wander far from their hosts. You might consider getting a captive-cloned BTA for her when your tank is settled in (6 months or so).
