Red Spotted Goby

The Red Spotted Goby is a small freshwater fish with red spotting, an expressive resting posture, and interesting territorial displays. It spends much of its time close to the substrate, moving between stones and shelters rather than schooling in open water.

Fish details

• Scientific name: Rhinogobius rubromaculatus
• Size offered: Contact us for the current size
• Adult size: Up to approximately 5–6 cm, with variation between populations
• Origin: Taiwan
• Water type: Freshwater
• Temperament: Territorial with similar bottom dwellers; may suit a carefully chosen community

Recommended aquarium conditions

• Aquarium: 20 US gallons long or larger, with several separated territories
• Temperature: 18–24°C (64–75°F)
• pH: 6.0–8.0
• Water movement: Good oxygenation and moderate circulation, with calm sheltered areas

Use smooth stones, sand or fine gravel, and small caves to create a network of retreats. Break up sightlines across the bottom so fish can move out of one another's view. Keep the aquarium mature, covered, and clean; constant harsh flow across every resting spot is unnecessary.

Diet and feeding

Provide small live or frozen invertebrate foods, such as daphnia, brine shrimp, and appropriately sized bloodworms. Prepared foods may be accepted but should not be assumed. Place food close enough for the goby to find it before faster fish take everything.

Compatibility and care

Suitable upper-water companions are peaceful fish with overlapping temperature needs. Avoid large predators, pushy bottom dwellers, and overcrowding. Small shrimp or fry may become prey. Give each goby access to cover and separate individuals if one is repeatedly excluded from food or shelter. Spot size and color intensity vary naturally; clean water, adequate feeding, and low-stress housing matter more than matching a photograph.
