Etymology: mesopotamicus: Named after Mesopotamia (the land between the rivers), referring to the Tigris-Euphrates basin where the species is found.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 6.0 - ?. Subtropical; 15°C - 24°C (Ref. 83325)
Asia: southern Karkheh River basin of Iran and at Qarmat `Ali in Iraq at the northern part of Basrah on the Shatt al Arab, the confluence of the Tigris and Euphrates rivers.

Max length : 2.4 cm SL male/unsexed; (Ref. 83325); 2.9 cm SL (female)
Morphology | Morphometrics
soft rays: 10 - 12. Can be diagnosed by its pigmentation, meristics, and in multivariate morphometric and meristic space: males have clear margins to the unpaired fins, no bars on the caudal fin and have 10-15 clearly defined flank bars. Females possess irregular blotches or spots on the flank. Twelve of 14 meristic characters are significantly different for males and 9 of 13 meristic characters for females, although ranges overlap in all cases. Discriminant function analyses indicate that the variables with the best discriminating power are pectoral fin rays (13-15), scales to pelvic fin (5-7), postorbital length (16% HL) and caudal peduncle length in males; and pectoral fin rays (14-15), scales to pelvic fin (5-8), scales to dorsal fin (4-5), total scales (27-30) and predorsal length in females ( 23% SL) (Ref. 83325).
Found only in two localities in a 25 m wide river and a 30 m wide canal branching from that river. The river had muddy bottom and the principal plant materials were rushes and reeds while the canal had also muddy bottom but the principal plant materials were filamentous green algae (Ref. 83325).
