Omnivores, in the wild they eat very small invertebrates and plants. In the aquarium they will accept a wide range of foods including flake, small pellets, bloodworms and brine shrimp.


It is not that hard to tell the difference between males and females. Females will be a lot plumper and rounder in the body and males are more elongated.
Black Neon tetras will breed successfully in clean water where the hardness of the water is soft (less than 4-5 dGH.)
Black neon’s are egg scatterers and their eggs (usually around 200 or so) will stick to leaves leaves, ornaments, glass and rocks in the aquarium, commonly in the early hours of the morning (in darkness.) NOTE: Watch the fantastic video of them spawning at the bottom of this page.
Parents should be removed from the tank after they laid the eggs as the adults will eat the eggs and fry.


Originating in South America, where they inhabit Paraguay and Southern Brazil in the Paraguay, Rio Taquari, Pantanal of Mato Grosso do Sul river systems, they are a schooling fish that hang out around plants and driftwood.

In the home aquarium, Black Neon Tetras like plenty of cover and do really well in a planted aquarium. They do little damage to plants and should be considered for such a setup.

PH should be kept between 6.5 to 7.3 allowing them to be kept with many other tropical specimens in the same environment.
Black Neon Tetras are a schooling fish and should be kept in a group of at least 6 for them to feel safe. They look terrific the way the swim around in a group -it is very pleasing to the eye.
