The Longfin Serpae Tetra is a striking freshwater fish known for its deep red body, flowing elongated fins, and bold personality. A longfin variant of the classic Serpae Tetra, it adds dramatic movement and color to community aquariums, especially when kept in groups. These fish are active mid-water swimmers and can display mild fin-nipping behavior if kept in too small a school or with slow, long-finned tankmates. When maintained in proper numbers and a well-structured tank with plants and open swimming space, they become more settled and display natural schooling behavior. Their coloration intensifies with good diet, stable water conditions, and subdued lighting, making them a vibrant centerpiece in planted tanks.
