Sorry, I can only check back on a limited basis. I will work on getting a pic for the backside Tun, however I can tell you the skimmer requires at least 4 inches of clearance between the tank and wall to fit, and it does extend above and below the tank's (AGA 10) height specs. If you need specific numbers, any website that sells seaclones usually provides the product's dimensions, as does the AGA website for tank dimensions.
