with those chest like that it mean they are pretty old fish, so the price is ok.
If that is true about the chest area, then your saying 1 year of age is old? I have a buddy that bought 2 flowerhorns from petco... I was told they were old(in which they weren't) and that they didn't come from petco(in which they did).
