Habitat Comments:No specific life history information is available for this sub-species. Basic life history requirements are assumed to be similar to other tui chub which inhabit isolated pond and spring outflow systems. Railroad Valley tui chub occupy a variety of habitats ranging from Twin Springs Slough which incorporates both a flowing stream system and a small reservoir, to isolated artesian well and spring outflow systems in central Railroad Valley. The Owens tui chub, which inhabits similar small isolated desert habitats, prefers pool habitats with low current velocities and dense aquatic vegetation that provide adequate cover and habitat for insect food items.
