Neon Goby

The Neon Goby is a brilliant little saltwater fish that is highly prized by reef aquarists for its stunning electric blue stripe running from head to tail over a black body. Native to the Caribbean and Florida waters, these diminutive fish are not only beautiful but also serve as cleaner fish in the aquarium, removing parasites from other fish. They are one of the most reef-safe fish available and will not bother corals or invertebrates. Neon Gobies are active and constantly on the move, perching on rocks and coral branches while waiting for cleaning clients or hunting for small food items. They are relatively hardy for a marine fish and can be a good choice for aquarists transitioning from freshwater to saltwater. Their cleaning services, brilliant coloration, and peaceful nature make them an excellent addition to nano reef tanks and larger reef aquariums alike.

Care Requirements

Tank Setup

Neon Gobies thrive in nano reef tanks of 10-20 gallons or larger reef systems. Provide live rock with caves and crevices for shelter and perching spots. They appreciate water flow but not strong currents. A mature tank with established biological filtration is essential. They are completely reef-safe and can be kept with all types of corals.

Water Quality

• Temperature: 72-78°F (22-26°C)
• pH: 8.1-8.4
• Water Hardness: Hard, dKH 8-12
• Ammonia/Nitrite: 0 ppm
• Nitrate: <10 ppm

Feeding

These carnivores accept a variety of small meaty foods. Offer mysis shrimp, brine shrimp, and finely chopped seafood. They will also graze on parasites from other fish as part of their cleaning behavior. Feed small amounts twice daily. Target feeding helps ensure they receive adequate nutrition.

Behavior & Compatibility

Neon Gobies are peaceful and can be kept singly or in pairs. They may set up cleaning stations where other fish come to have parasites removed. They are compatible with virtually all reef-safe fish and invertebrates. Their small size means they should not be housed with large predatory fish that might eat them.

Tips for Success

• One of the best starter marine fish for those new to saltwater
• Provide live rock with hiding spots and perching areas
• They may spawn in the aquarium if conditions are right
• Can be kept in pairs; ensure adequate space for territories
• Their cleaning behavior benefits other fish in the tank
• Regular feeding is important as they have high metabolisms
• Completely reef-safe; will not harm corals or invertebrates
