The Tanganyika Lampeye Killifish (Lamprichthys tanganicanus) is a peaceful and colorful fish that grows to a larger size than most killifish. Its "lampeye" name refers to the horizontal crescent at the top of its eye that seems to “glow” under the aquarium light. It is much more colorful than most other lampeye species, boasting bright green, blue, and yellow markings. Unlike most killifish, which inhabit swamps and ditches, this species is native to the massive Lake Tanganyika. It will often spawn in the aquarium and it is a non-annual killifish that is much longer lived than some of its "annual" relatives.


The Tanganyika Lampeye Killifish mainly occupies the top level of the water column almost exclusively. It is not afraid to jump, so it must be kept in an aquarium with either a lid/hood/canopy or at least a significantly lowered water level. It will not eat or bother plants and it will appreciate the cover, especially with floating plants. This fish is well suited for a heavily planted aquarium and will even appreciate some floating vegetation.


While this fish is compatible with other peaceful fish and invertebrate species that thrive in a planted aquarium, care must be taken to not add species that will outcompete the Tanganyika Lampeye Killifish for food. Also, other fish species will eat most of the fry of the Tanganyika Lampeye Killifish when it is spawning, so other tankmate species are not recommended if dedicated breeding and rearing of fry is desired. While many killifish are kept in pairs, the Tanganyika Lampeye Killifish seems to thrive and show the best coloration in groups. It will feel most secure when kept in groups of 6 or more, preferably with females outnumbering males. It is safe with peaceful invertebrates too large to be considered prey. Though it is native to Lake Tanganyika, which is also home to many great cichlid species, the Tanganyika Lampeye Killifish will not fare fell with any aggressive cichlid species. More peaceful shell-dwelling cichlid species might be compatible in a large enough aquarium. 


The Tanganyika Lampeye Killifish is not necessarily a picky eater, but it requires a varied diet of foods that can be consumed at the top of the water column. High quality dry, frozen, and live meaty foods of manageable size will all be accepted.
