Aquarium Requirements

• Minimum Tank Size: 30 gallons (115 litres)

• Temperature: 24–27°C (75–81°F)

• pH: 8.1–8.4

• Specific Gravity (Salinity): 1.020–1.025

• Aquascape: Provide a deep sandy substrate (3–5 inches) for burrowing, along with live rock and crevices for hiding and shelter

Suntail Gobies thrive in established aquariums with stable water parameters and ample space for natural digging and burrow-building behavior.

Diet and Feeding

Suntail Gobies are carnivorous and feed primarily on small meaty foods:

• Frozen or live foods such as mysis shrimp, brine shrimp, and finely chopped seafood

• Sinking micro-pellets formulated for carnivorous marine fish

• Feed 2–3 times daily, placing food near the substrate to encourage natural foraging

A varied diet supports health, vibrant coloration, and active behavior.

Temperament and Compatibility

Suntail Gobies are peaceful, bottom-dwelling fish that coexist well with other non-aggressive species. Their symbiotic relationship with pistol shrimp adds an interesting dynamic to the aquarium.

Tankmate Recommendations:

• Suitable: Clownfish, small gobies, blennies, firefish, and other peaceful reef species

• Avoid: Large predatory or aggressive fish

Providing deep sand and hiding places allows the goby to display natural behaviors and reduces stress.
