A largely hardy species that is ideal for beginners to the hobby

Black widow Tetra are from the Rio Paraguay and Guaporé basins in Brazil and Argentina.

Black Widow Tetras are a shoaling species, and are best kept in large numbers. For best results we recommend keeping at least 6 in a shoal - the more the happier they will be.

Ideally slightly acidic water conditions are provided between 6.5pH - 7pH however they will happily live in conditions ranging up to pH of 7.5 or higher. Temperatures should range between 24-26°C.

Black Widow Tetra should be fed a variety of flake, frozen, freeze dried and live foods for a varied diet.  Being omnivores they will happily accept a wide range of foods. Growth Size  6 cm 

Black Widow Tetra are peaceful community fish and are generally accepeted by a wide range of tank mates. Please see the compatability chart below for more information.

Males are noticeably slimmer than the female, and have pointed dorsal and anal fins. Like most Tetra they are not parental so may eat spawned eggs, however they are not difficult to breed, but will require a separate tank to raise fry.
