The Colon Goby (Coryphopterus dicrus) is a peaceful species that is reef-safe, admired for its slender body, translucent coloration with subtle patterns, small size, and active nature, often found darting near sandy bottoms or reef rubble. This goby’s unobtrusive yet engaging behavior makes it a charming addition to community aquariums.
Males typically grow slightly larger, may develop more intense markings, and can exhibit subtle territorial or courtship behaviors, while females and juveniles remain smaller with softer coloration and are less dominant.
They reach about 2–2.5 inches in length and should be housed in aquariums of at least 10 gallons, though larger tanks are ideal for groups or to better mimic their natural reef environment. Provide a fine sandbed, live rock for crevices and hiding spaces, and open swimming areas. A secure lid is necessary, as gobies are prone to jumping when startled.
Maintain stable water parameters: salinity around 1.020–1.025, temperature between 72–79°F, and pH between 8.1–8.4.
Their diet should consist of mysis shrimp, enriched brine shrimp, copepods, finely chopped meaty foods, and high-quality micro pellets. Frequent small feedings help ensure these small, active fish receive enough nutrition.
With proper care, the Colon Goby makes a standout addition to reef aquariums, offering peaceful temperament, natural beauty, and interesting darting behavior.
