Acanthobrama marmid, commonly known as the Basrah Minnow, is a cyprinid fish endemic to the Tigris-Euphrates river basin. It is characterized by its moderately compressed body, relatively large scales, and a distinctive dark lateral stripe. This species plays a significant ecological role in its native freshwater ecosystems.
Physical Characteristics
- Body shape
- compressed
- Coloration
- Silvery-grey to olive-brown on the back, fading to silvery-white on the belly. A prominent dark lateral stripe extends from the operculum to the caudal peduncle. Fins are typically translucent or slightly dusky.
- Scale type
- cycloid
- Mouth position
- subterminal
- Distinctive features
- Moderately compressed body, Relatively large, cycloid scales, Prominent dark lateral stripe, Small, subterminal mouth, Absence of barbels
- Dorsal fin
- Short, with 3 unbranched and 7-8 branched rays. Originates slightly behind the pelvic fin origin.
- Tail fin
- Deeply forked, with pointed lobes.
- Pectoral fin
- Relatively short, not reaching the pelvic fin origin.
- Distinctive fins
- Anal fin is moderately long, with 3 unbranched and 10-13 branched rays. Pelvic fins are small.
Identification Tips
Lateral Stripe
Look for the distinct dark lateral stripe running along the flank, which is a key identifying feature.
Scale Size
Observe the relatively large scales compared to many other minnow species in the region.
Fin Ray Counts
Accurate identification often requires counting fin rays, particularly for the dorsal (3 unbranched, 7-8 branched) and anal (3 unbranched, 10-13 branched) fins.
Mouth Position
Note the small, subterminal mouth, indicating its feeding habits.
Habitat
- Water type
- freshwater
- Depth
- Typically found in shallow to moderate depths, often near the bottom or in mid-water.
- Environment
- Inhabits slow to moderately flowing rivers, canals, and associated wetlands. Prefers areas with submerged vegetation, rocky substrates, or muddy bottoms. Tolerant of some turbidity.
- Geographic range
- Endemic to the Tigris-Euphrates river basin, including its tributaries and associated marshlands, primarily in Iraq, with some presence in adjacent areas of Iran, Syria, and Turkey.
Aquarium Information
- Care level: intermediate
- Temperament: peaceful
- Diet: omnivore
- Minimum tank size: 75 gallons (280 liters)
- Temperature: 68-77°F (20-25°C)
- pH level: 7.0-8.0
- Hardness: 10-20 dGH
- Compatibility: Generally compatible with other peaceful, similarly sized fish. Avoid highly aggressive or very small, delicate species.
- Special requirements: Requires a well-oxygenated tank with good filtration. Prefers a substrate of sand or fine gravel, with some rocks and driftwood for hiding places. Live plants are beneficial but should be robust enough to withstand occasional nibbling. Schooling species, so best kept in groups of 6 or more.
Wild Information
- Conservation status: least concern
- Seasonality: Spawning typically occurs in spring and early summer, influenced by water temperature and flow regimes.
- Market price: N/A (not typically sold commercially for food or aquarium trade outside its native range)
- Commercial importance: low
- Taste: Mild, somewhat earthy
- Texture: Flaky, with small bones
- Cooking methods: Frying, Grilling, Stewing
- Nutritional value: Good source of protein and omega-3 fatty acids, typical of freshwater fish.
Key Facts
Endemic to Mesopotamiainteresting
The Basrah Minnow is exclusively found in the ancient and historically significant Tigris-Euphrates river system.
Ecological Indicatorbehavior
Its presence and health can serve as an indicator of the overall ecological condition of its freshwater habitats.
Dietary Generalistbehavior
As an omnivore, it feeds on a variety of small invertebrates, algae, and detritus, contributing to nutrient cycling in its ecosystem.
Safety Information
Safe- Safety level: safe
- Venomous: No
- Edibility: edible
- Handling notes: No specific handling precautions are required beyond standard fish handling practices to minimize stress to the fish and prevent injury to the handler (e.g., avoiding sharp fins).

Rutilus frisii
Rutilus frisii typically has a more robust body, a terminal mouth, and lacks the prominent dark lateral stripe of Acanthobrama marmid. Scale counts and fin ray counts also differ.
Other Acanthobrama species
Various Acanthobrama spp.
Differentiation from other Acanthobrama species can be challenging and often requires detailed morphological analysis, including fin ray counts, lateral line scale counts, and body proportions. Acanthobrama marmid is distinguished by its specific combination of scale size, body depth, and fin ray counts.
