SWEET he looks Great i LOVE those dark colors on him!! and yes you keep that water clean and feed him tons of shrimp and insects (in addition to his pellet of course) then he will get MONSTER status in no time! i would def fast him for a couple days until he starts to eat pellets as that will provide the most complete diet for him (as im sure you already know lol) but some can be more stubborn than others lol
