Hi I am looking into building a really shallow 48"x48"x12" high tank, which is about a 120 gallon tank that will be used to raise stingray pups. My question is how hard would it be to make this? Which is better for this: glass or acrylic? What is the minimum glass (or acrylic) thickness that you would recommend? And lastly where should I buy the glass from? thanks in advance
