Similar to Pseudopimelodus but the head is
very large and flattened and is the only species in
this genera. Dorsal fin short and the caudal fin is
rounded. The juveniles look similar to the Chaca
genera from Asia and like them are very predatory.
Aquarium Care: Not to be kept with
fish that are too small as they will be eaten, better
to be kept on their own or with large non-aggressive
species. Would need a large aquarium as this species
grows to 70cm. SL. Reproduction:
Has been bred in the aquarium, the eggs are adhesive.
Diet: Live foods such as earthworms
and frozen foods. Remarks:
Due to the latest paper by Oscar A. Shibattaet al. (Dec. 2021) there are now five species
in this genera with four of them now being being synonymized
The recovered phylogeny of the genus was (L. albomarginatus
, L. nigricaudus, L. apurensis, L. fowleri,
and L. alexandri).
São Francisco River basin. Type locality:
Aus Brasilien, wahrscheinlich aus dem Amazonenstrome.
