Dive sites in the Lembeh Straits can often be strewn with litter. While that sounds like a bad thing, on some occasions litter can create habitats for marine life. In this case an old Sprite bottle has become home to a fangblenny. After settling down in front of the bottle, I waited patiently for the fangblenny to pop its head out of the bottle to see what this new object was in front of it.
