Well to me it looks like a ZZMalau or Zhen Zhou X Kamalau. As far as grading it I am no expert or no judge. I could be nice and say its top grade but I will be honest. First I personally like the fish so this isn't my preference but anyway as far as a grade I would say slightly above low. I would imagine it is too young to tell for sure but usually high grade AAA fh will have a large, even, proportional head, full body pearling including around its head the thicker the better, color the brighter and more even the better, flowerline would have to be solid single, double, or triple row, and it would have to have an aggressive temperment. I like it however and it looks like some of the fish I just bred. Keep us updated as it grows and who knows maybe it will really blossom. As far as potential I think he has quite a bit for how big the fish is. Good luck.
