Rummy Nose Tetra
Hemigrammus rhodostomus
Family: Characidae
📍 Rio Vaupes & Amazon, South America
Named for its distinctive red nose and black-and-white striped tail, the rummy nose tetra is a stunning schooling fish that forms tight, coordinated shoals. It is more sensitive to water quality than the neon tetra and requires soft, warm, acidic conditions to look and behave at its best. The intensity of the red colouration serves as a reliable water quality indicator.
