Relevant Information:

Description: Orbital diameter contained 5.4-9.8 times in head length, snout length contained 1.8-2.1 times in head length; predorsal length contained 2.2-2.4 times in standard length; adipose fin separated from the dorsal fin by a distance contained 2.7-3.1 times in standard length; anal fin contained 1.8-2.1 times in standard length; maxillary and external mental barbels with margins having a very thin and dark membrane; internal mental barbels widely membranous. Anal fin rays 66-74; pectoral fin rays I+13- 16; pelvic fin rays I+5, caudal fin rays 15 (Littmann et al. 2021). Habitat: Recorded in the Yata sub-basin (Amazon Basin) (Careaga et al. 2020). Diet: Feeds on zooplankton (López-Fernández & Winemiller 2000). Because they are a filter feeder they are not really suitable for the home aquarium (Grant, Steven 2021). Etymology: The specific name fimbriatus: Latin for fringed, allusion not explained, possibly referring to the prominent but easily torn membrane along enlarged and paired inner mental barbels.
