I almost everyday see puctata in our local market , hardly ever reach more than 30cm( common size 5-7") , most hardy fish in channa group , tropical so no special requirement , last year in october- November saw a pair with fries , male and female are not more than 5-6" or even smaller, I love their patterns ,I would say the fact they can grow up to 90cm (75 being more realistic) and therefore require a big tank while not displaying much color.
That on top of having contenders like Micropeltes, Maruloides and diplogramma in their size range, I can see why they are not too popular.
If they are sub-tropical, it's even worse because they require a special care that the other tropical ones of the same size do not.
Just my opinion as taste is different for most people.
It looks good though!
