Periodini

Periodini is a genus of small, freshwater fish belonging to the family Cyprinidae, which includes minnows and carps. The genus is native to the Indomalayan realm, with species found in rivers and streams across Southeast Asia, including countries like India, Bangladesh, and Myanmar. Periodini are typically small, with most species reaching lengths of less than 10 centimeters. They are known for their distinctive coloration, which often includes shades of blue, green, and yellow, and may feature vertical or horizontal stripes.

The genus includes several species, with the most well-known being Periodiopsyllus, which is characterized by its elongated body and large, prominent eyes. Other species in the genus include Periodiopsyllus, Periodiopsyllus, and Periodiopsyllus. These fish are often found in shallow, fast-flowing waters, where they feed on small invertebrates and plant material.

Periodini are of interest to both scientists and aquarium hobbyists due to their unique appearance and behavior. They are also important in their natural habitats, as they play a role in the food chain and help maintain the health of aquatic ecosystems. However, some species are threatened by habitat loss and pollution, making conservation efforts important for their long-term survival.
