Magnus Goby

The Magnus Goby is a small and attractively marked shrimp goby characterized by its white to cream body adorned with orange spots and vertical bars. The combination of warm orange markings against a pale background creates an eye-catching appearance that makes this species a delightful addition to nano and small reef aquariums. Reaching a maximum size of only 3.5 inches, the Magnus Goby is perfectly suited for smaller tank setups.

Like other Amblyeleotris species, the Magnus Goby forms a symbiotic relationship with pistol shrimp of the genus Alpheus. The goby perches attentively at the burrow entrance, its large eyes scanning for potential threats, while maintaining physical contact with the shrimp through gentle fin touches. When danger is detected, the goby flicks its tail to alert the shrimp, and both retreat into the burrow. This behavioral partnership is one of the most fascinating aspects of keeping this species.

The Magnus Goby is an excellent choice for beginner aquarists. It is hardy, peaceful, reef-safe, and adapts quickly to captive foods. A 10-gallon aquarium is sufficient for a single specimen or a goby-shrimp pair, though a larger tank provides more stability. A sand substrate of at least 1-2 inches and some rubble are essential for burrowing. This species readily accepts frozen mysis shrimp, enriched brine shrimp, and quality sinking pellets.
