It has been more than a century since the Chocolate Lyretail Killifish became well-known in the aquarium hobby. In addition to other well-known species such as Fundulopanchax Gardneri, Aplocheilus Lineatus, and Aphyosemion striatum, this species is quite popular. Due to the ease with which this species may be kept and bred, many experienced Killie keepers (Killinuts) would recommend that a novice Killie keeper begin with this species. It is an ideal beginner’s fish.

As a consequence of the German merchant ship Waganda’s trip to Port Gentil in Gabon, in 1928 the African species was collected by Öser . These fish were imported alive into Germany and this is a record of this species. Therefore, the aquarium-strain Lyretail has been circulating from hobbyist to hobbyist for a very long time.

There is a wide distribution of fish in the coastal forests of northwest Gabon to the southwest of the Congo. Additionally, the species has a wide range of hues; some populations are more vibrant, while others are more subdued. Port Gentil (BSWG 97/24), Cape Esterias (EBT 96/27), and Parq du Mondah (BDBG 04/19) are three of the natural populations of A. australe now available in the hobby. In addition to the collector’s last name and place code, location codes often provide a year of collection.

Captivating Colors

On the body of the male, the base color is brown with numerous red spots and markings. And the part behind the head shows a bright iridescent green hue. The anal, caudal, and dorsal fins of this fish are paler brown, and are dotted with many red markings. In males with a much older age, the fin rays on the anal and dorsal fins are often much longer. In addition to the beautiful lyre-shaped caudal fin, the fish is also known as a lyretail due to the extension of its white fins up to about 1/4 inches (6 mm) and further. 

The female killifish, like most of the Killies species, is drab when compared to its male counterparts, which has a lighter brown body with somewhat fewer red spots and without paired fins–the caudal is rounded, rather than the extended structure seen on the males.


The best manner in which to maintain this peaceful species is to keep it in a small soft water aquarium with a good supply of plants and bogwood to make sure it remains healthy. It is also highly recommended to use a peat filtration system. It is perfectly safe to keep this species alongside other small, peaceful fish with the same requirements and needs such as pencilfishes, Kuhli loaches, Corydoras species or Croaking/Sparkling Gouramis, and so on.

In an aquarium, the water movement must be gentle in order to mimic the slow movement of water that these fish are accustomed to in their wild habitat. It would be great if your aquarium had surface cover in the form of floating plants, and it would be especially useful if the coverslides matched tightly, as these fish are accomplished jumpers. Chocolate Lyretail Killifish does not have a seasonal occurrence, making it an excellent choice as a killifish first-time keeper who has no experience caring for this family of fish.

This species, Chocolate Lyretail Killifish, is strictly a carnivore, which means that they will not be seen chomping on the plants you have placed in the community tank. As a result of their tiny size, you may feed them cyclops, baby brine shrimp, mosquito larvae, daphnia, and other similar foods. They like meaty items, but we must make sure that they are sized appropriately for the killifish’s mouth so that they do not find it difficult to chew them.

Chocolate Lyretail Killifish are a fantastic option for both beginning and seasoned fish keepers due to their ability to adapt to a variety of water conditions. Furthermore, since they are naturally calm, they can get along with a wide variety of different fish species with relative ease.

The Chocolate Lyretail killifish, like the majority of other killifish species, may be found in shallow waters in the wild.

You should set up a long, shallow tank with a lots of ornamental elements such as driftwood, pebbles, and gravel to make it seem more appealing. As an additional precaution, you should give floating plants so that the fish have plenty of hiding places.

The aquarium should have a reasonable size in terms of volume because there should be plenty of space for the fish to swim about and explore. If you overcrowd your aquarium with a large number of different species of fish, the Chocolate Lyretail killifish will get anxious and become lethargic, their colors becoming bland.

You should also make sure that your aquarium is adequately secured so that they do not have any opportunities to escape. They are fond of leaping, just like any other killifish, and they cannot survive for an extended period of time out of water.

Chocolate Lyretail Killifish are non-annual killifish, which means that their life cycle is not restricted to a single calendar year. As a result, they prefer to spend their time in permanent bodies of water in the natural environment. Currents in the water of your aquarium should be avoided at all costs since they will interfere with the swimming activity of your fish.

They are at ease in dim lighting, so you should notice that there is no sunshine shining directly into the aquarium all of the time.
