Relevant Information: |
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.
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). 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. |
