We were able to obtain this very rarely imported species of bottlenose catfish from Peru
. Ageneiosus marmoratus has a very wide distribution in Amazonia. The species is a predator that prefers to feed on live fish. The largest specimen known to science was about 20 cm long (ours are currently 12-15 cm long). It can be suspected that A. marmoratus is only the juvenile of another species of bottlenose catfish, namely A. inermis, because no one ever has found so far sexually active specimens of A. marmoratus. A. inermis becomes about 40-50 cm long.
The males of all species of Ageneiosus develop very large dorsal spines
during breeding season and a penis-like organ. During mating the males fixes the female with the dorsal spine. There is an internal fertilization. After the breeding season the dorsal spine becomes casted off, comparable to the antlers of a deer, and the penis-like organ becomes reduced so that males and females cannot be distinguished externally outside the breeding season.
