Description
At an adult size of little more than 1 inch, black neons are suitable for small aquariums. They are a schooling fish and should always be kept in groups of a half dozen or more. They also make a nice addition to a larger community aquarium, as they are peaceful and easy to care for.
At the bare minimum, you could keep six in a 10-gallon tank, but do yourself a favor and get 10–15 of them for a 20-gallon tank or larger.
