Shortstripe Goby

The Shortstripe Goby is one of the smallest members of the Elacatinus cleaner goby complex, reaching a maximum length of just 1 inch. This diminutive Caribbean species is distinguished by a shortened yellow or white lateral stripe that does not extend the full length of the body, contrasting with the full-length stripes seen in related species like the Broadstripe Goby and Neon Goby. Its dark body provides a dramatic backdrop for this abbreviated marking, creating a distinctive and easily recognizable appearance.

Like other Elacatinus species, the Shortstripe Goby is a dedicated cleaner fish that establishes stations on sponges and coral heads where it services larger fish by removing ectoparasites and dead tissue. This behavior has evolved as a mutualistic relationship — the goby obtains nutrition while the client fish receive parasite removal. Even in the home aquarium, this cleaning instinct persists, and the Shortstripe Goby will actively attend to willing tankmates.

Captive-bred Shortstripe Gobies are available, and their tiny size makes them perfect candidates for even the smallest nano reef aquariums. A 10-gallon tank provides ample space for one or a pair. This species is completely reef-safe, utterly peaceful, and produces virtually no bioload. Its bold personality and fearless approach to much larger fish make it far more engaging to observe than its diminutive size might suggest.
