My crab Freddie loves this thing! I thought it just bubbled and caught fire, that's all. But this thing looks like some kind of whirlwind that picks Freddie up every time he steps inside! Since then he has tried and played 7 times today so I think he likes it. I wish it had a remote control for the LED but you can't choose the color. But the color changes smoothly, so everything is fine. My aquarium had an algae problem so I turned off the main light and left it on for now. It's bright enough to see but not too bright. I have a video for the brightness, the bubbles and to show Freddie shooting the bubbler. Me and I think Freddie loves it :] UPDATE: My tank is only 10 gallons so not very big. presumably low enough for the bubbler to shoot Freddy out of the tank. So now I've closed the hole in my lid. If you do this, make sure your lid doesn't have any holes, or the bubbler isn't next to a lid hole like mine does, or at least your tank is bigger than mine!
