African Longfin Tetra 3.5cm

African Longfin Tetra 

The African Longfin Tetra, is a super underrated and simplistic fish to add into a planted or community aquarium. These peaceful fish are often overshadowed by similar-looking species like Congo tetras however this species reaches around 8cm, is active, and has a vivid green tail. Originating from the rivers of Africa, this species is a testament to the beauty and diversity of African tetras. Even in a biotope setting these fish will make a stunning and unique addition.

Caring for African Longfin tetras is incredible, as they are relatively hardy fish that adapt well to life in a well-maintained aquarium. The body colour of these fish is a silvery metallic blue with darker grey shades towards the tail. From the eye to the start of the tail these tetras sport a flash of lime green which is a very unique colour to this species. One of the best aspects of these fish is their naturally occurring long fins which are tipped with white. To contrast all of this, the African long-fin tetra have a jet-black tail stripe which also acts as a great way to differentiate them from Congo tetras when juveniles.

Sexing African Longfin Tetras can be somewhat challenging but there are a few key differences to look for. Males are typically more vibrant in colour with a more pronounced iridescence and have longer, more elaborate finnage. They may also have a rounder body shape, especially when gravid. These fish spawn like any other tetra by scattering eggs into the aquarium, they exhibit no parental care so it is best to breed them in a dedicated breeding system.

Tank Recommendations for your African Longfin Tetra
Being a larger-body tetra and incredibly active fish, the African Longfin tetra needs an aquarium with a minimum volume of 100 litres. They are however an easy to care for species. A sand or gravel substrate would be fine for these fish as well as a lot of plant growth which not only makes them contrast well but also makes them more comfortable in the aquarium to swim out in the open. These African Longfin tetras are softwater fish meaning they require a low PH. They can be kept in PH as low as 6 and will even look stunning in a black water aquarium setting with warm lighting which will accentuate their green tones.
