Description
The White-backed Goby is a captivating marine fish recognized by its prominent white dorsal stripe and its unique symbiotic relationship with pistol shrimp. It typically resides in sandy or rubble areas, where it shares a burrow with its shrimp partner, acting as a vigilant lookout while the shrimp maintains their shared home. This peaceful species makes an excellent addition to a reef or fish-only-with-live-rock aquarium.
