The Cardinal Tetra is a schooling fish, which feels more at ease when kept in a school of at least 5, but a larger group would always be better. Keeping at least 10 or more of them together will also help boost their coloration.
South American river basins do not feature a lot of plants, so there is no need for heavy planting. Instead, provide a lot of open swimming space, as Cardinal Tetras are very active and fast swimmers. As for the water chemistry, they prefer very soft and acidic water with a pH between 4.5-7, and water temperature between 73-81 degrees Fahrenheit.

It will often spawn in the aquarium.
The Norman’s Lampeye Killifish occupies the top level of the water column almost exclusively. It is not afraid to jump, so it must be kept in an aquarium with either a lid/hood/canopy or at least a significantly lowered water level. It will not eat or bother plants and it will appreciate the cover, especially with floating plants. This fish is clearly best suited for a heavily planted aquarium.
