Just a word of advice, get tiles darker than you want them to be because when placed in a fish tank, the color is much lighter than how what you anticipated. I wanted a more dark tan-color, but i ended up getting a beige-white looking floor. Also, make sure u get inside measurements of the tank, not the general external dimensions. The debris never stays on the floor as the powerheads always swifting it. Last but not least, anyone that is a noob like I am in construction, just make sure you score the tile up and down several times to get a fine a cut. Can't wait for my first water change
Most importantly, SHOW PICS!!!!!
