Overview: Glowlight tetra is another popular tropical fish species, very similar to Neon and Cardinal tetras in terms of size and shape. However colour is very different, they tend to be dark grey, almost black like with bright red stripe across the body. Shoaling fish so should be kept in group of at least 6, they will school well with other tetras as well. They look the best in the darker spots of the aquarium where the colour, especially the red stripe really comes to live. Well planted tanks are great as they will often spend time in and around plants, but they like some open water for swimming too.
