As a fish watching guide, we are trained to find small stuff as well. The question is how far our eyes can reach to these "Small Stuff". 5 centimeter or 3 centimeter? Maybe? But the stuffs below are even less than 1.5 centimeter. Believe its or not?
Macro lover always like to search for very small fish. It is one of the challenge. Challenge your own eyes. Once you get to find very small fish, you will feel satisfy. And sometime you will feel proud of yourself.
