Red Dragonet

Red Dragonet (Synchiropus stellatus / Synchiropus spp.)

 

The Red Dragonet, also known as the Red Scooter Dragonet or Red Starry Dragonet, is a striking and highly sought-after marine fish admired for its vibrant red, orange, and maroon coloration accented by intricate blue and white markings. These bottom-dwelling dragonets are constantly on the move, gracefully gliding across live rock and sand in search of tiny crustaceans. Their peaceful nature and unique appearance make them a favorite among experienced reef aquarists looking to add both beauty and interesting behavior to their aquarium.

Behavior & Role in a Reef Tank

Red Dragonets are peaceful, slow-moving fish that spend nearly all of their time exploring the rockwork and substrate in search of copepods, amphipods, and other tiny microfauna. Their unique "walking" movement, using their large pectoral fins, gives them a fascinating appearance unlike most reef fish.

They are excellent additions to mature reef aquariums with abundant live rock and established pod populations. Unlike many active swimmers, Red Dragonets remain close to the substrate and rarely bother corals or other invertebrates.

 

Compatibility & Caution

Red Dragonets are completely reef safe and generally ignore corals, shrimp, snails, and other reef inhabitants. They do best with other peaceful fish and should not be housed with aggressive or highly competitive feeders that may outcompete them during feeding.

One of the biggest challenges with this species is ensuring they receive adequate nutrition. Many specimens rely heavily on naturally occurring copepods, making mature aquariums essential. Captive-bred individuals often adapt more readily to frozen foods and prepared diets.

Avoid keeping multiple dragonets together unless you have a very large aquarium or a confirmed compatible pair, as males may become territorial toward one another.

 

Care Level

Moderate to Advanced

Recommended Water Parameters:

• Temperature: 24–26°C (75–79°F)
• Salinity: 1.024–1.026
• pH: 8.1–8.4
• Ammonia/Nitrite: 0 ppm
• Nitrate: Below 20 ppm (preferably under 10 ppm)

 

Diet:

• Copepods (primary natural food)
• Amphipods
• Live enriched brine shrimp
• Live blackworms (occasionally)
• Frozen Cyclops
• Frozen mysis shrimp (many captive-bred individuals accept these)
• Finely chopped frozen seafood
• High-quality small sinking prepared foods (for trained specimens)

A mature aquarium of at least 50 gallons with abundant live rock is strongly recommended to sustain a healthy pod population.

 

Tank Mates

Ideal companions include:

• Clownfish
• Gobies
• Firefish
• Cardinalfish
• Blennies
• Fairy Wrasses
• Flasher Wrasses
• Reef-safe Angelfish
• Peaceful Tangs

Avoid:

• Large aggressive Wrasses
• Dottybacks
• Triggers
• Puffers
• Hawkfish that may prey on pods
• Fast, aggressive feeders that monopolize food

 

Fun Fact

Unlike most fish, Red Dragonets are covered with a protective mucus coating instead of traditional scales. This natural slime layer helps protect them from parasites and skin infections, making them one of the more unique fish found in the marine aquarium hobby.
