Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic; pH range: 8.0 - ? ; dH range: 10 - ?; non-migratory. Subtropical
Eurasia: endemic to and only native finfish of Azraq Oasis, Jordan, where it is presently in danger of extinction because of a recent lowering in water level.
