Garra salweenica is a species of ray-finned fish in the family Cyprinidae. It is characterized by its specialized oral disc, which allows it to adhere to substrates in fast-flowing waters. This species is part of the diverse Garra genus, known for its rheophilic adaptations.
Physical Characteristics
- Body shape
- elongated
- Coloration
- Generally brownish to grayish dorsally, fading to a lighter ventral surface. May exhibit subtle darker blotches or a lateral stripe depending on the individual and specific locality. Fins are typically translucent or slightly dusky.
- Scale type
- cycloid
- Mouth position
- inferior
- Distinctive features
- Well-developed oral disc on the ventral side of the head, used for adhesion to rocks., A pair of rostral barbels and a pair of maxillary barbels., Tuberculate snout in mature males, especially during breeding season.
- Dorsal fin
- Single dorsal fin, typically with 8-9 branched rays. Origin usually anterior to the pelvic fin origin.
- Tail fin
- Forked caudal fin.
- Pectoral fin
- Pectoral fins are horizontally oriented and often broad, aiding in maintaining position in strong currents.
- Distinctive fins
- Pelvic fins are also horizontally oriented and contribute to adhesion.
Identification Tips
Oral Disc
Look for the prominent, suctorial oral disc on the underside of the head, characteristic of the genus Garra.
Barbels
Observe the presence of two pairs of barbels (rostral and maxillary).
Body Shape and Coloration
Note the elongated body and brownish-gray coloration, often with subtle markings. The overall appearance is adapted for benthic life in flowing water.
Fin Placement
The dorsal fin origin is typically anterior to the pelvic fin origin, a key diagnostic feature within some Garra species.
Habitat
- Water type
- freshwater
- Depth
- Typically found in shallow to moderate depths of rivers and streams.
- Environment
- Fast-flowing, clear, and well-oxygenated rivers and streams with rocky or gravelly substrates. They prefer areas with strong currents where they can graze on periphyton.
- Geographic range
- Endemic to the Salween River basin in Southeast Asia, specifically found in Myanmar and Thailand.
Aquarium Information
- Care level: intermediate
- Temperament: peaceful
- Diet: omnivore
- Minimum tank size: 30 gallons
- Temperature: 22-26°C (72-79°F)
- pH level: 6.5-7.5

- Compatibility: Generally compatible with other peaceful, similarly sized fish. Avoid very aggressive or fin-nipping species. Best kept in groups of 5 or more.
- Special requirements: Requires highly oxygenated water with strong current. A substrate of smooth rocks and pebbles is ideal, mimicking its natural riverine habitat. Provide plenty of hiding spots and smooth surfaces for grazing. Good filtration is essential.
Wild Information
- Conservation status: least concern
- Seasonality: Breeding patterns are not well-documented, but likely tied to monsoon seasons and increased water flow in its natural habitat.
- Market price: Low
- Commercial importance: low
- Taste: Not commonly consumed
- Texture: Not commonly consumed
- Nutritional value: Unknown, not a food fish
Key Facts
River Specialistbehavior
Garra salweenica is highly adapted to life in fast-flowing rivers, using its specialized oral disc to cling to rocks and feed on algae.
Algae Grazerbehavior
Its primary diet consists of periphyton and biofilm scraped from submerged surfaces, playing an important role in riverine ecosystems.
Endemic to Salweeninteresting
This species is found exclusively within the Salween River basin, highlighting its specific habitat requirements and geographic isolation.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: not recommended
- Handling notes: No specific handling precautions are required beyond standard fish handling practices to minimize stress and injury to the fish. They are not venomous and do not possess sharp spines that pose a significant threat.
