Morish Idol or Banner Fish?

[daplatapus]

I had couple schooling banner fish in my tank for 8 months or so. Just providing a home for a friend while they moved and re-set up their tank. They are easy to keep. But they eat TONS and get quite big. They never really bothered any of my fish. From what I've experienced they need lots of room to swim. I wouldn't put them in anything smaller than a 6' tank with minimal rockscape.
