Sympatric and synotopic with Compsura heterura, Serrapinnus heterodon and S. piaba in the type locality. Feeds mainly on vegetal matter and algae, but also takes insects and microcrustaceans (Ref. 96867). Jerep, F.C. and L.R. Malabarba 2014 A new species of <i>Serrapinnus</i> Malabarba, 1998 (Characidae: Cheirodontinae) from Rio Grande do Norte State, northeastern Brazil. Neotrop. Ichthyol. 12(2):301-308.

It differs further by having 5 cusps in the premaxillary and dentary teeth (vs. 7 to 9 in S. calliurus, S. micropterus, and S. piaba, 9 to 11 in S. sterbai, and 10 to 12 in S. gracilis and S. littoris), terminal mouth (vs. slightly superior mouth in S. microdon), an incomplete lateral line (vs. complete lateral line in S. heterodon), dorsal fin mostly hyaline (vs. dorsal fin with an anterior and proximal dark blotch in S. notomelas), and by lacking black spot in the posteroventral region of the abdomen (vs. present in S. kriegi) (Ref. 96867).Description: dorsal-fin rays ii,9; anal-fin rays ii-iv,17-20; pectoral-fin rays i, 10-12; pelvic-fin raysi,7-8; scale rows from lateral line to pelvic-fin origin 4 or 5; abdominal vertebrae 15; and caudal vertebrae 18 or 19 (Ref. 96867).
