Red Margin Shrimp Goby

The Red Margin Shrimp Goby is a delicate and attractive species named for the distinctive red margins that edge its dorsal and anal fins. The body is predominantly white to pale gray with subtle markings, creating an elegant contrast with the vibrant red fin edges. This small species reaches a maximum size of about 3 inches, making it well-suited for nano and small reef aquariums.

Like its Amblyeleotris relatives, the Red Margin Shrimp Goby forms a mutualistic symbiotic relationship with pistol shrimp. The goby provides vigilant surveillance from the burrow entrance while the shrimp excavates and maintains their shared home. Maintaining physical contact through the shrimp's antennae on the goby's tail, the pair communicates danger signals that trigger a rapid retreat into the safety of the burrow. This remarkable interspecies partnership is endlessly fascinating to observe.

The Red Margin Shrimp Goby is a hardy and easy-to-care-for species that makes an excellent choice for beginners. It requires a minimum tank of only 10 gallons with a sand substrate for burrowing. The species is completely reef-safe and poses no threat to corals or invertebrates. It readily accepts frozen and prepared foods and adapts quickly to aquarium life. A tight-fitting lid is essential, as like most gobies, this species can and will jump if startled.
