[3] Occurs in a variety of non-turbid stream habitats with substrates from bedrock to silt covered (Platania 1980).

A typical riffle species occurring over gravel and rubble, especially when aquatic vegetation is present.

[11] Hubbs (1985)[3] reported marked drop in reproductive activity when water temperature was raised from 20 to 23 °C.

[6] In the South Concho River, TX, eggs averaged 1.3 mm in diameter, and increased in number with female size; average number of eggs in females examined was 74, with a range of about 15–200.

Hubbs (1985)[3] noted that no difference in egg production could be correlated with daylength.
