Micro Dragon Goby (Schismatogobius Ampluvinculus)

Micro Dragon Goby (Schismatogobius ampluvinculus) — The Miniature Dragon of the Stream Aquarium

The Micro Dragon Goby (Schismatogobius ampluvinculus) is a fascinating and rarely seen nano goby from the fast-flowing hill streams of Southeast Asia. With its boldly patterned body of mottled browns, creams, and blacks — reminiscent of dragon scales — and its distinctive flattened, streamlined profile, this diminutive goby is a captivating and unusual addition to the stream-style aquarium. Small in size but enormous in character, the Micro Dragon Goby is a true conversation piece for the discerning nano fish enthusiast.

A Dragon in Miniature

The Micro Dragon Goby is a master of camouflage and a creature of the substrate, using its modified pelvic fins to cling to rocks and gravel in fast-flowing currents. Its intricate, dragon-like patterning provides exceptional camouflage against natural stream substrates, while its bold, alert eyes and active foraging behaviour make it endlessly engaging to observe. Each fish is uniquely patterned, adding an element of individuality to every specimen.

Care Profile

• Scientific Name: Schismatogobius ampluvinculus
• Origin: Southeast Asia — Philippines and surrounding islands; fast-flowing, clear, oxygen-rich hill streams
• Size: Up to 3–4 cm
• Temperament: Peaceful toward other species; may be territorial toward conspecifics — provide ample hiding spots and visual breaks
• Diet: Carnivore — feeds on small invertebrates, micro worms, baby brine shrimp, and sinking micro foods; also grazes on biofilm
• Water Temperature: 22–26°C
• pH: 7.0–8.0 (prefers neutral to slightly alkaline, well-oxygenated water)
• Tank Size: Minimum 40L; strong filtration and high flow recommended to replicate natural stream conditions
• Note: Requires well-established tanks with mature substrate and hiding spots among rocks and pebbles; sensitive to poor water quality

Aquascape Compatibility

The Micro Dragon Goby thrives in stream-style aquariums with smooth river rocks, fine gravel, and vigorous water movement. It is best kept with peaceful, similarly sized stream-dwelling species that will not outcompete it for food — small danios, hillstream loaches, and other nano gobies make excellent tankmates. Its cryptic colouration and low-profile behaviour make it a fascinating and unobtrusive addition to any naturalistic stream biotope.

Ancient in appearance, captivating in behaviour — the Micro Dragon Goby is the miniature dragon your stream aquarium has been waiting for.
