The Platinum Rummynose Tetra (Hemigrammus rhodostomus “Platinum”) is a small, peaceful schooling fish prized for its striking silvery body and bright red nose, making it a colorful addition to community aquariums. Native to the slow-moving rivers and blackwater habitats of South America, they thrive in soft, slightly acidic water with gentle filtration, subdued lighting, and planted or decorated tanks that offer hiding spaces. Platinum Rummynose Tetras are active and social, best kept in groups of at least 6–8 to exhibit natural schooling behavior and reduce stress. They are omnivorous and do well on a varied diet of high-quality flakes or micro-pellets, along with live or frozen foods such as brine shrimp, daphnia, or bloodworms. Maintaining clean water and stable parameters is essential, as they are sensitive to poor water quality. With proper care, they display vibrant coloration and peaceful community behavior, living for several years in a well-maintained tank.
