It is diagnosed from A. jacksonii by having a deeper caudal peduncle, its depth 8.1-9.5% of standard length vs. 4.8-7.9%, and a deeper body, body depth at anus 13.5-15.8% of standard length vs. 9.6-13.2%; it is diagnosed from A. ruziziensis by having a wider interorbital width, 28.3-31.7% of head length vs. 23.4-25.1%, and a deeper body, body depth at anus 13.5-15.8% of standard length vs. 11.1-12.9%; it is further diagnosed from A. frieli by having fewer gill rakers on the first gill arch, 6-8, rarely 5 or 9 vs. 10-11, rarely 9 or 12, and a longer caudal peduncle, its length 16.8-20.9% of standard length vs. 14.4-16.4%; it is further diagnosed from A. crassus by having more branched pectoral-fin rays, 9 vs. 7-8, rarely 9, and a longer caudal peduncle, its length 16.8-20.9% of standard length vs. 13.3-15.5%. Aquarium Care: Can be kept in aquaria with a small grained gravel or sand substrate, and well planted with a slight current to facilitate their natural habitat. Provide rockwork and caves. This genera prefer cooler temperatures in the aquarium. Diet: Mosquito larvae, Tubifex, Cyclops, Daphnia, grindal worms, vegetable food, tablet and flake. Etymology: The specific name of lujani for this African catfish is named in honour of Nathan K. Lujan who collected the holotype and most paratypes of this species, and who has made excellent contributions to our knowledge of freshwater fishes.
