Paraguay Tetra (Hyphessobrycon Paraguayensis) is a small but vibrant freshwater species of fish that originates from the rivers and streams of Paraguay and Brazil. These fish grow up to 3 cm in length, and their colors range from bright yellow to orange and sometimes even red. Their fins are usually transparent, though they may have a hint of yellow or orange. They are a peaceful species and are generally peaceful with their tank-mates. Paraguay Tetra prefer to live in schools of 6-8 individuals and prefer a well-planted aquarium with plenty of hiding spots and plenty of free swimming space. They are omnivores, so they should be fed a variety of foods including flakes, pellets, and frozen or live foods.
