Pufferfish uses sand as its medium for incredible undersea art

Mysterious geometric "crop circles" - some as large as six feet in diameter 80 feet below the surface - were recently observed on the sandy seabeds of Amami Oshima in Southern Japan.

Pacific Sun Diuna T5 lighting system

All this light is controlled wirelessly via bluetooth with four to five independent channels.

Reef Aquascaping Inspiration

I'm in the process of setting up a new reef tank and went searching for aquascaping ideas, stumbling across the youtube channel by 'otpp225' from Taiwan. To be honest, I don't know anything about him. I don't know if these videos are of his aquariums, are his designs, or whether he's a hobbyist or a professional. What I do know is that these reef aquascapes are beautiful, unique, and inspiring.
