The Italian redfin is a freshwater fish that lives only in the rivers and lakes of Italy. It has a tall silvery body and red fins.
The Italian redfin differs from the common redfin in head shape and the number of scales in the lateral line. It serves as an important part of the food chain in Italian water bodies and helps control the growth of aquatic vegetation.
Collects food from plants, water surface, and bottom.
Immature form that undergoes metamorphosis before adulthood.
