Range and Identity
Gambusia nobilis is distinct from more widespread mosquitofishes that may occur in nearby waters. The Pecos basin connection helps narrow the geographic context but does not establish identification on its own. A spring record should retain the features used to distinguish the fish.
Habitat and Behavior
Adults occupy vegetated spring water and connected outflows. The spring source, downstream flow and plant cover together describe the habitat more precisely than a general river label. A fish from an outflow is not necessarily living in the main channel of the Pecos itself.
Food and Life History
The compiled upper reference is 4.8 centimeters total length, with a common value of 3.3 centimeters. No maximum weight is calculated from those figures. The retrieved account does not establish a detailed migration route, so separate spring records should not be connected by an invented movement pattern.
Field Note
Record the specific spring or outflow alongside the river basin. That detail is especially useful for a fish whose native distribution depends on localized water sources.
