Got a sweet deal on a 125g tank today, $200 for the tank, a wood cabinet/stand and matching canopy, and tons of decorations as well as a Marineland 280 & 400, picking it up tomorrow! 
Only reason I got it is because I've always wanted Piranhas, and when I saw this guys tank: http://www.monsterfishkeepers.com/forums/showthread.php?t=412685 I fell in love with it.
Im trying to aim for that same type of natural look, and had a few questions. It doesn't look like his lights extend over the entire length of the tank, and numerous piranha setups Ive seen only have a light that covers about a third of the tank, kept in the middle. Is this what I should be looking for as well, or would it be better if I got something to go over the entire length of the tank?
Also, that threadstarters tank looks like it has blackwater extract or something in it, or maybe its just the black background that makes it look dark. Is it something thats absolutely necessary, or mostly aesthetic? I realize its to keep the pH low and acidic, but right now my tap is about 7.0 pH and very little hardness, wouldn't that suffice?
Also if you guys have any recommendations on what types of plants to get (should I/could I keep live plants in with pygo nats?), any websites that youve used for plants, or anything in general pertaining to the tank and the setup. Its my first piranha tank, so I would love all feedback!
