Nothobranchius rachovii, or the bluefin notho, is a species of freshwater annual killifish from Mozambique and South Africa.[1] It can grow up to 6 cm (2.4").[2] It is popular among killifish enthusiasts, who raise them from eggs in aquaria.

Variants

Aside from the typical orange and blue variant, there is Nothobranchius rachovii KNP Black, which has much darker colors, and was collected from the wild in Kruger National Park, South Africa in 1984,[3] and Nothobranchius rachovii var. Red, which has a red head with turquoise highlights.[4] The females of all varieties are more neutrally colored.

In the Aquarium

Nothobranchius rachovii can be housed in a 40–60 litre (10–15 gallons) aquarium. Males are aggressive toward other males of the same species.[5] They can be kept in a community tank of similar-sized peaceful freshwater tropical fish.
