Description
Black emperor tetras hail from the San Juan and Atrato basins of Colombia. Growing up to 4cm in length, these peaceful freshwater fish are a dark, heavily patterned colour form of the emperor tetra. Males are the more colourful, with extended fins, a long central tail ray and a blue iris.
Black emperor tetras are shoaling fish, best kept in groups of six or more, ideally ten, to help them feel secure and promote natural behaviour. Rival males are mildly territorial, so consider a well decorated aquarium with plenty of space.
Great tank mates include other tetras, livebearers, rasboras and corydoras. Avoid housing them with larger fish that may see them as food.
At Wirral Aquatics our black emperor tetras enjoy a diet of Artemia, Insect meal and Mussel as well as fresh and frozen daphnia and brine shrimp.

Ordering livestock
We strive to ensure that we honour all orders placed online. However, we are a small, busy shop and tracking livestock inventory can be challenging. If we are unable to fulfil your order, we will contact you as soon as possible to discuss options so that you can decide how you would like to proceed.
If livestock are appearing out of stock on our website, it does not necessarily mean that they are not available in store. If there is something that you are looking for, please contact us and we will be happy to discuss what is possible.
If you would like to view footage of the particular fish that you are looking to purchase, please contact us and we will send footage as per your request.
