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.
Habitat preferences
Reported habitat associations include medium to large rivers, streams and small rivers, creeks.
The source records associations with sand, gravel. 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.
Recorded spawning months are Apr, May, Jun, Jul for the source’s reporting region (AL). This is a regional calendar, not a range-wide schedule.
Size and recorded longevity
FishTraits reports a maximum total length of 14.5 centimetres. Some entries use an estimated asymptotic length; this value should not be treated as a certified record catch.
