They are nice looking fish when healthy, but not spectacularly coloured. I bought mine last time as a baby for $20. It grew an inch a month & in less than a year, it was approaching a foot long in a 100g 4' tank. I then set up a 6'6" fowlr 160g fowlr for it but it got sick & died during the transition period.
Here's an old pic of mine:
