Common name: Shrimp Gobies

Tomiyamichthys is a genus of gobies known for their symbiotic relationships with pistol shrimps. These small, bottom-dwelling fish are popular in the reefkeeping hobby for their intriguing behaviors and compatibility with other peaceful tank inhabitants. They often pair with shrimps, which construct and maintain a shared burrow, while the goby serves as a lookout for predators. Their peaceful nature and small size make them suitable for most reef aquariums, where they add both activity and interest.
