I am one of the most common and smallest fish on the reef. I live in sandy areas with a snapping shrimp. I stand guard over our burrow all day long. When shrimp-gobies reproduce, the females lay the eggs, but the males watch over the eggs until they hatch.
I am a watchman, always on guard. I live in a very close, or symbiotic, relationship with certain snapping shrimp. The snapping shrimp will make our home, a small burrow, in the sand. I protect the burrow so that other species don't steal it, and I also protect the snapping shrimp from its predators. We both benefit from hanging out together, so it is a mutualistic relationship.
I love to eat microscopic animals called zooplankton, but I will also snack on tiny shrimps and crabs. I only eat other animals, so I am a carnivore.
Reefs are in danger, and that means so is my home!
