The Aphyosemion Australe or the Gold Lyretail Killifish has got to be one of the most stunning, nano centrepiece fish and is arguably coloured species in the killifish family. This is pretty easy to care for fish but they can be sensitive to parameter swings so it would be better to have this species on the bucket list once there is a decent level of experience gained with aquarium keeping. They are however incredibly vibrant and contrasting fish with fun personalities and are great for smaller aquariums as well.
