3-D backgrounds by Penn-Plax do more than improve the look of your tank. Their holographic images shift when viewed from different agles, just as they would in real space. This adds a sense of depth to the background, making your tank appear larger than it really is! These backgrounds come pre-cut to several common tank dimensions but can easily be trimmed to fit any tank.
