I found this Whip Coral Goby whilst doing a night dive at the 'Hafa Dai Wreck' whilst in Palau. If you look closely you can see the inside of the goby. They can be incredibly hard to photograph sometimes, due to being so small and skittish.
Also, is there any photographers having problems with losing quality when uploading photos?
