Appearance

A. australe comes in a two colours. The wild type are brown and called 'chocolate' in the aquarium hobby and a man made 'gold' form exists which is orange; this form was spontaneous mutation bred by a Finnish aquarist name Hjerssen in 1952. JJ Scheel in "Rivulins of the World World (TFH PRess, 1970) deleted the pointed out these were not a separate specues and deprecated the name Aphyosemion australe hjersseni. Males can reach a length of around 6 cm, with females being slightly smaller. The caudal fin is lyre-shaped, which is characteristic of the genus. The females also are less colourful; their body colouration is brownish tan for the wild form and a light tan for the gold/orange form, and they have rounder fins.[3]

In the aquarium

The Cape Lopez lyretail is one of the most popular and commonly available species of killifish. Spawns readily in the aquarium in nearly any water, spawning in fine-leafed water plants, such as aquatic moss. The fry emerge after 14 days at a preferred temperature of 26 °C (79 °F). They adapt well to any variety of commercially prepared foods, flake or frozen livefoods but like all killifish do better with living foods cultured or caught from clean sources.
