This photo is taken when I visited Sydney Aquarium in 2011. From the first time, It looks like a combination of blue and yellow lights, naturally, a bit mysterious.With me it feel like blue and yellow is dancing in a night festival. This is created by the reflex of the fishes in weak light. The interesting is that it can't be seen in normal eyes, but only can be caught by cameras with long exposure and small aperture ( less light). I realised beautiful in life is not only in my eyes, it can be hidden anywhere, under any normal things and still waiting to be discovered.
