Pink Spot 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, live rock for shelter, and crevices for retreat

Pink Spot Gobies thrive in established aquariums with stable water parameters and a substrate suitable for digging and natural burrow-building behavior.

Diet and Feeding

Pink Spot Gobies are carnivorous and feed primarily on small invertebrates:

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

• High-quality sinking pellets formulated for carnivorous marine fish

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

A varied diet promotes health, coloration, and active sand-sifting behavior.

Temperament and Compatibility

Pink Spot Gobies are peaceful, bottom-dwelling fish that coexist well with other non-aggressive species. They are often paired with pistol shrimp, forming a fascinating and mutually beneficial 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 ensures the goby can express natural behaviors and reduces stress.

Reef Compatibility

✅ Reef Safe

Pink Spot Gobies are reef safe and do not harm corals or sessile invertebrates, making them suitable for reef aquariums.

• Maximum Size: Up to 8 cm (3 inches)

• Lifespan: 3–5 years with proper care

• Difficulty Level: Moderate

• Natural Behavior: Peaceful, burrow-dweller, often forms symbiotic relationship with pistol shrimp
