The ember tetra is a freshwater fish of the characin family of order Characiformes. It is native to the Araguaia River basin of Brazil and was discovered in 1987 and named in honor of the fish explorer Heiko Bleher's mother.

One of the most important parts of Ember Tetra care is keeping them in a group. These fish don't want to be on their own. We recommend that you keep at least 10-15 of these together to ensure that they feel comfortable and enriched by their buddies. Shoaling fish that are kept alone will be subject to extreme stress
