What's the price. Looks alright, doesn't look like he will get large hump if you care for it, pearls are good but none on the head, flowerline isn't so strong.
The problem with FH's and other similar fish is that they can be very tricky to sex unless ya get a good view of the vent. If the vent is bigger then the anus it's female but if it's the same size or smaller it's male. If the guy left a number I'd ask him to take a good clear pic of the vent and anus, like this, to confirm if it's male or not.
