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.
