dont worry, as long as hes out at night swimming and eating he will be fine. Mine had the same temperament for years until he reached 7" and started displaying beautufil colors (not always), and swam with lights on.
give him time, hiding places, a same sized buddy and feed live fish
oh, adding the proper salt near well oxygenated areas helps too
