These colorful little fish are great for the nano aquarist. They are a schooling fish, so they prefer to be in a group of 5 or more. They love planted aquariums as the coverage makes them feel safe. Ember tetras are an easy going fish that can do well with other types of small fish and invertebrates, such as shrimp. It is recommended to feed these fish a color enhancing pellet, such as New Life Spectrum's Ultra Red.
