Can't tell what this awesome retic is?

Hi there, I have a nice awesome looking reticulated python that I purchase at the San Diego reptile show 1 1/2 ago. Still I have no idea what he can be. I feed him a jumbo rat every 7 days for the past year and I haven't seen him grow as much, i got him at 5ft and now he's 7ft. so I'm think he could be a dwarf? He also has a wicked granite pattern running from his neck down half way threw his body and also resembles a platty? There are times where he glows kinda lime green. Maybe you guys can help me out with having to find out what this awesome retic is. Thanks for looking
