Rummy nose tetras are considered the ultimate schooling fish in the freshwater hobby. Their tight, synchronized formations are unmatched by any other tetra species. The vivid red nose serves as a health indicator — bright red means healthy, pale red means stressed. They prefer soft, acidic water and are slightly more demanding than neon tetras.
