Aquarium Care:
Grows rather large and would need a large tank to
accommodate it and a good water flow in the aquarium.
Diet: In their natural habitat part of their
diet is the mollusc, Limnoperna fortunei
which is an invasive species. Etymology:
According to Valenciennes (1840), Latin cognate of
vieille, old woman, from its local common name, vielle
à longue queue (“long-tailed old woman”),
referring to its filamentous caudal-fin ray; vieille
(velha in Portuguese, vieja in Spanish) is a name
it shares with several loricariid, doradid and callichthyid
catfishes (e.g., Loricariichthys anus) in Buenos Aires,
Argentina, allusion not explained nor evident. Remarks:
Not exported very often due to their large size.
