I have both acrylic and glass tanks (2 of each). The acrylic tanks are wonderful to be able to clean because they are so lightweight (even their 50 gallon) and the water is very clear. The downside is that they usually have a structural support at the top that can make it difficult to get equipment and decorations down to certain areas. They also scratch easy so you must use special scouring pads to to leave scratches. In the end, I still say the old-fashioned glass models are my favorite, just because they have a completely open top that allows you to place items anywhere you want to - but then again the sheer weight of them makes it impossible for a small person like myself to clean the glass models - can't really set it in the bathtub to clean it like you can the acryilc. So as yu look at different tanks and see a nic acrylic one, make sure you'll be able to live with any structural supports on top of the tank that will interfere with your plans. The lightness and clarity of an acrylic tank is certaintlu worth something.
