Clown Goby Green

Also known as the Green Coral Goby or Citron Green Goby

The Clown Goby Green is a tiny and peaceful reef fish that brings a gentle pop of color and personality to any aquarium. Their bright green shade makes them easy to spot even though they spend most of their time perched on corals or resting on branches. They adapt well to smaller tanks, stay calm around tank mates, and are ideal for both beginners and experienced aquarists. In the wild, they live among coral branches in the Indo Pacific where they hide and feed in sheltered reef areas.

Habitat and Tank Requirements

Natural Habitat: Green Clown Gobies naturally live in shallow coral reefs in the Indo Pacific, especially in branching SPS corals where they stay protected and forage for small food particles.
Tank Environment: Provide plenty of rockwork and branching corals or artificial coral structures to make them feel safe. They prefer calm to moderate flow and do not need large swimming areas. Works well as a single fish or as a pair in larger tanks.

 Water Parameters:

• Temperature: 74–80°F (23–27°C)
•  Salinity: 1.023–1.025
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: Below 20 ppm
• Alkalinity: 8–12 dKH

Essential Equipment:

• Quality filtration for stable water conditions
• Moderate lighting
• Regular weekly or biweekly water changes

Diet and Feeding

Clown Goby Green are carnivorous and prefer small meaty foods that match their tiny mouths.

Recommended Foods:

• Pellets or micro granules for small marine fish
• Frozen mysis shrimp
• Frozen brine shrimp
• Copepods
• Enriched micro food
  

Feeding Schedule: Feed 1 to 2 times daily and give small portions they can finish quickly. Offering a variety of foods helps maintain energy, growth, and coloration.

Behavior and Compatibility

Temperament: Calm, shy, and gentle. They spend time perching on corals and rock surfaces. Territorial behavior may appear if multiple gobies are kept in a very small tank.

Tank Mates:

• Compatible with peaceful fish such as firefish, small wrasses, blennies, dartfish, royal grammas, and other nano fish
• Use caution with larger semi aggressive fish that may bully or outcompete them
• Avoid keeping with aggressive species or large predators

Breeding Potential

Green Clown Gobies can breed in home aquariums if provided a calm and stable environment. They lay eggs on coral branches or flat surfaces and the male guards them. The fry require very fine foods such as rotifers or specialized larvae diets to grow successfully.
