Thanks guys, he seems to have more color everyday. So the original whiteness must have just been stress from shipping.
Still no aggression, although he does follow some of the cichlids around whenever he catches the scent of food around feeding time, but he hasn't actually gone after anyone just yet. I'm going to call the place I got him from and see if he was on live food before I got him, because he's still really hesitant with dry food. He'll eat 1-2 pellets a day, and it takes forever before he even considers eating them
