Range and Identity
Dionda episcopa is recorded in the Rio Grande drainage above the Devils River region in Texas, New Mexico and Mexico. Related Dionda can have restricted neighboring distributions. The scientific identity and exact tributary should therefore remain connected when comparing small minnows from nearby waters.
Habitat and Behavior
Adults occupy rocky pools and sometimes runs in headwaters, creeks and small rivers. Filamentous algae are a frequent association. This does not make every algal patch equivalent habitat; current, substrate and the particular stream remain useful details in an observation.
Food and Life History
The maximum reference is 7.7 centimeters total length, with 5.5 centimeters given as a common size. Algae and other plants dominate the stated food account. No independent maximum mass or precise migratory behavior is established in the retrieved summary.
Field Note
Distinguish the algae actually associated with the fish from a general statement about green water. Attached filamentous growth and suspended algae describe different features of a stream.
