Looks absolutely precious, can be placed well, you can either use the suction cups to secure it to the disk, or how I did it sink in gravel (of course, so that the lights still out light) and thus objects (wood, stones, crystals, decoration) beluchten. The lighting effects make themselves naturally is best in the dark, but they are also visible lit. I especially appreciate that you can control the light separately from the air, so you can even at night off the light, which the fish is good.
