Yeap, need a pic.....If it's just a low grade flowerhorn...then you coulda just grabbed a trimac for about 40-50% cheaper.
But it really depends if YOU like the fish.....at 11" the fish is pretty developed and looks awesome whether the grade....if ya like it, it's worth it! But then again if he bought it for $180, it must be a pretty nice Flowerhorn then!
Is it pearly? Hump? Thick body? Any red? How's the flowerline?
