Ecology
This species can be found in gravel and bedrock bottomed pools and runs of small creeks and rivers. Juveniles typically inhabit quieter, slow-paced waters.
Characteristics
The Alabama shiner reaches a maximum of 13 cm (5.1 in) and eats aquatic insects such as midge and blackfly larvae. Its physical characteristics include a bright orange/yellow tail and a black spot on the base of the tail. They have the largest breeding tubercles of the genus Cyprinella. These are horny projections on their head and body that aid in spawning. They are observed spawning in crevices between rocks. The mouth on the bottom of the head suggests bottom feeding. This species has diamond shaped scales and a compressed body.

Diet and feeding
The FishTraits compilation records these diet categories for this species: invertebrates or larval fish. These are broad categories, not a claim that every individual consumes every example in a category.
Reported feeding positions include bottom feeding. The compilation combines published observations; diets can vary with age, locality, and available food.
Habitat preferences
Reported habitat associations include streams and small rivers, creeks.
The source records associations with sand, gravel, cobble, bedrock. An association indicates reported use, rather than an exclusive requirement.
Reproduction and parental care
The compilation reports a representative maturity age of 1 years. Its maturity field summarizes mean, median, or modal estimates, usually for females; male estimates can be used when female data are unavailable. It is not a fixed age at which every fish first breeds.
Batch or serial spawning has been reported somewhere in the species’ range. This does not establish the same spawning pattern for every population.
Recorded spawning months are Apr, May, Jun, Jul for the source’s reporting region (MS). This is a regional calendar, not a range-wide schedule.
The reproductive-guild classification includes hiding a brood without subsequent guarding.
Size and recorded longevity
FishTraits reports a maximum total length of 9.5 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.
Recorded longevity in the compilation is 3 years. Wild observations were preferred, but captive records were accepted where wild records were unavailable, and unspecified records were assumed wild. The value is not a guaranteed wild lifespan or an aquarium life expectancy.
