Sulphur Goby

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

• Alkalinity: 8–12 dKH

• Ammonia & Nitrite: 0 ppm

• Nitrate:< 10 ppm

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

Sulphur Gobies thrive in established aquariums with stable water conditions and suitable substrate for natural burrow-building and sand-sifting behavior.

Diet and Feeding

Sulphur Gobies are carnivorous and feed primarily on small invertebrates:

• 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, offering food on or near the substrate to encourage natural foraging

A varied diet ensures optimal health, vibrant coloration, and active behavior.

Temperament and Compatibility

Sulphur Gobies are peaceful, bottom-dwelling fish that coexist well with other non-aggressive species. They are often paired with pistol shrimp, creating a fascinating symbiotic relationship.

Tankmate Recommendations:

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

• Avoid: Large predatory or aggressive species

Providing deep sand and hiding places allows the goby to exhibit natural behaviors while minimizing stress.

Reef Compatibility

✅ Reef Safe

Sulphur Gobies are reef safe and do not harm corals or sessile invertebrates, making them ideal for reef aquariums.
