I'm still getting the Xingu used to the tank and all, so Im just gonna leave the substrate be for now, then in a couple months Ill change it to something of more color. The fish likes the tank and has a favorite spot behind a big rock. Pics seem small taken with cell and most of the time if I get too close to the tank the fish moves to behind the rock. Better pics will come when the fish is more comfortable with humans approcahing the tank and staying out in the open which is why patience of pics isnt liked but needed.
