Comments: Occur in lowland water bodies, with little current (Ref. 26100).  Inhabit streams with clear water and enter subterranean karstic waters during winter or droughts.  Spawn in shallower parts of streams where females probably lay 2-3 portions of eggs.  Threatened due to pollution, habitat destruction and introduction of exotic species;  limited data suggest that its decline in the last 10 years is likely to continue due to water abstraction and introductions of exotic species (Ref. 59043).
