Thank you for the constructive comments.Yes,the head growth is what i'm trying to groom now.Do you have any tips how to improve it besides genetics.I have been feeding live red worms and ranchu lord pellets now.This fish has now gain in bulk in body mass but head still need major improvement.
It also is now kept in a 3 x 2 feet blue tub all by itself with a little water current for it to swim & exercise.
