Species Profiles
Rummy Nose Tetra
Hemigrammus rhodostomus
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.

Phenacogrammus interruptus
Congo tetras are the showstoppers of the tetra family. Males develop spectacular flowing fins with an iridescent rainbow sheen that shifts from blue to gold to green under aquarium lighting. They are larger than most tetras (up to 3.5 inches) and need a spacious, well-planted tank to display their full beauty. Peaceful but shy — they thrive with calm tank mates.
