Rubripinnis

Rubripinnis is a genus of small, freshwater fish belonging to the family Cyprinidae, which includes carps and minnows. The name "rubripinnis" is derived from the Latin words "ruber," meaning red, and "pinna," meaning fin, referring to the red fins of some species. These fish are native to Southeast Asia, particularly in the Mekong River basin and its tributaries.

The genus includes several species, with the most well-known being Rubripinnis rubripinnis, commonly known as the redfin barb. Rubripinnis species are typically small, with adults reaching lengths of about 5 to 7 centimeters. They are characterized by their elongated, slender bodies and distinctive red fins, which are used for courtship displays. These fish are omnivorous, feeding on a variety of aquatic plants, insects, and small crustaceans.

Rubripinnis species are popular among aquarium hobbyists due to their vibrant colors and relatively easy care requirements. They are often kept in community tanks with other peaceful fish species. However, they are sensitive to water quality and require well-maintained aquariums with stable water parameters.

The genus Rubripinnis is not considered threatened, but some species may face local declines due to habitat loss and pollution. Conservation efforts focus on protecting the Mekong River basin and its tributaries, which are critical habitats for these fish.
