Well, I received some pictures of the tank today. It is a sweet tank but there are 3 vertical support pieces on the front and back walls of the tank. These are perpendicular with the tank walls and look to be about 2-3" wide. I think these sticking out could cause problems for the rays as mine like to climb the front glass a lot. Plus, all the sides are coated with coraline algae. If the tank didn't have the vertical pieces, I would buy it in a heart beat as the price is right. I am going to look into a local acrylic tank manufacturer for a 6'x3' tank now.
