The Bivittatum Killi (Aphyosemion bivittatum) is a small killifish from the Lagos region of West Africa. Males develop bright orange and red tinted fins that really stand out, especially when they're displaying to each other.
Despite their appearance, they're relatively peaceful fish and do well in planted aquariums with plenty of cover. Like many killifish, they appreciate calm water and a little patience while they settle in.
A great reminder that some of the most colorful fish in the hobby stay under a few inches long.
