Relevant Information:

Description: Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 14 - 17. Distal portion of the upper labial extension distinctly elongated, forming acute tip which sometimes appears as an enlarged terminal fimbriae. Aquarium Care: Provide a sandy substrate as it likes to dig looking for morsels. Diet: Tablet, pellet foods and also frozen foods such as bloodworm. Remarks: The first three thumbnail images depict a very similar looking species which is reported to be from the Rio Nanay in Peru which flows through Iquitos. This species along with another from the Amazonas have been termed as 'Nanay Form' and 'Amazon Form'. This excludes the true species which is from the Rio Negro. There are differences in Variation in oral-hood morphology in all three species. Three groups were parsed: (Sabaj, 2005) L. cataniai sensu stricto (Rio Negro and Casiquiare canal), L. cf. cataniai Amazon form (Amazonas basin excluding Nanay and Negro) and L. cf. cataniai Nanay form (specimens largely from Río Nanay, Peru).
