Relevant Information:

Distinguished from congeners except A. occidentalis in having a uniformly-coloured body. It differs from A. occidentalis in having triangular (vs. oval-shaped) tooth patches on the upper jaw. Previously considered a synonym of A. occidentalis, this species is known only from the Lake Chad drainage. Teugels et al. (1991) considered the genus Auchenoglanis to be comprised of two valid species: A. biscutatus and A. occidentalis. Due to the work carried out recently (2010) by Michael Retzer there are now 8 in this genus with six new species, A. acuticeps, A. biscutatus, A. occidentalis, A. sacchii, A. sengali, A. tanganicanus, A. tchadiensis and A. wittei. The main description for A. acuticeps is that it has small round spots in a regular pattern on the body, adipose fin, caudal and dorsal fin. This species was once thought of as A. occidentalis but the original description of this species differs greatly from A.acuticeps. Aquarium Care: It is very tolerant to most water parameters and as such you can keep it in a low p.H. (6.5) with larger Characins or Barbs or even in a Lake Tanganyika setup with Cichlids from that lake in harder water, but my choice would be to stick with the former soft and acidic conditions for a more contented individual(s). Remarks: Fishbase has still to ratify these changes (see Fishbsase link) but Catolog of Fishes has done so.
