Remarks | Lives in the lower reaches of rivers within the limit of the brackishwater and the first rapids (Ref. 35381). Very abundant in estuaries; prefers dead tree trunks and the vast zones of flooded vegetation (Ref. 27188). Also occurs on the muddy bottoms of the banks occupied by Montrichardia arborescens, moving together Loricaria cataphracta and Pimelodus blochii according to the tide. Feeds mainly on unicellular algae and then on protozoa, rotifers, nematodes and arthropods as accessory food items. |
