The Black Tiger Dario is a beautiful freshwater nano fish. These little fish typically only reaches 1.5" and only require a 2.5 gallon aquarium, but the larger, the better. Black Tiger Darios are peaceful fish and can be kept with community fish. It is best to keep your Dario in groups of 6 or more but keep in mind that you should keep more females than males; when keeping males together, you should have a larger aquarium to prevent aggression.
