Glass Bloodfin Tetras are a peaceful and relatively active shoaling species that you can keep with many other fish species that enjoy similar water conditions making them an excellent choice for the community aquarium. Their comparative hardiness makes them ideal for the beginner aquarist. Rival males can sometimes squabble amongst themselves, and this is one of several good reasons you should always keep them in groups of at least six to eight individuals. They have an elongated slender body that is entirely transparent where you can see the stomach, brain and bones of the fish, except for the tail, which is a scarlet colour. Sometimes when these fish swim around and catch the light, they display a bluish iridescence. They favour live and frozen foods such as brine shrimp, cyclops, daphnia, mosquito larvae and bloodworm. However, It would be better for your fish if you fed them on a varied diet; therefore, it is advised that you also give them dried alternatives such as micropellets and flakes, which they will also happily accept. This will result in optimal health and the best colours for your fish.

Males are usually slimmer than females and have a hook shape at the beginning of their anal fin. They also present a dark stripe on the anal fin when they are in good condition and have slightly longer anal and dorsal fins. In contrast, females are noticeably fuller-bodied than males, especially when in breeding condition.
