Rummy-nose Tetra

The Rummynose Tetra (Hemigrammus rhodostomus) is a small, peaceful freshwater fish popular among aquarium enthusiasts. It is named for its distinctive bright red "nose" or head, which contrasts sharply with its sleek silver body. The tail features striking black-and-white horizontal stripes, adding to its appeal.
 
Native to the Amazon River basin in South America, Rummynose Tetras thrive in soft, acidic waters with stable conditions. They are shoaling fish, meaning they feel most comfortable and display their best colors when kept in groups of six or more. Known for their calm demeanor, they are excellent additions to community aquariums. Their sensitivity to water quality makes them a good indicator species, as they may lose color or show stress if conditions deteriorate.
