Description
Black widow tetras hail from the Paraguay and Guapore River basins of South America. Growing up to 6cm in length, these hardy freshwater fish are best identified by their flowing skirt fin silhouette.
Black widow tetras are a schooling fish and must be kept in groups of six or more to avoid them becoming highly stressed and aggressive.
Black widow tetras thrive in long aquariums that mimic their natural habitat; consider lots of live, tall background plants which will help them to feel secure whilst providing lots of open water swimming space. Dark substrates will accentuate the stunning colouration of your Black widow tetras and make their colours pop!
Black widow tetras are notorious fin nippers. Avoid housing them with slow moving or long finned fish such as fancy guppies, bettas or angel fish.
Black widow tetras are omnivores. At Wirral Aquatics our Black widow tetras enjoy a diet of EBO Pro Soft Artemia, Spirulina and Insect Meal as well as fresh and frozen brine shrimp and daphnia.
