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.

Gymnocorymbus ternetzi
Black skirt tetras (also sold as black widow tetras) are hardy, easy-to-care-for schooling fish with a distinctive flowing black anal fin that gives them their name. They come in natural silver-and-black and various dyed/modified versions (GloFish). The natural form is the healthiest choice. They can be mild fin nippers in small groups but are generally well-behaved community fish.
