Abstract: Trachelyopterus lucenai (Siluriformes: Auchenipteridae) is an invasive fish in restinga of Rio Grande, Rio Grande do Sul State, southern Brazil. In April 2007 remains of T. lucenai were found in the stomach of an individual of Lontra longicaudis (neotropical Otter) which was run over near a pluvial channel in the restinga area. The present record contributes to the knowledge on otters predation on exotic/invasive species in aquatic environments (Porciuncula & Quintelaa 2010). Aquarium Care: Good addition to the larger community tank and will not harass other occupants as long as they are not too small to be eaten on this catfishes night time prowls. Provide hiding places for it. Diet: In the wild they feed on they seem to feed mainly on shrimps, insects, juvenile loricariid catfish and characins. In the aquarium they will eat most aquarium fare. Remarks: In the paper by Porciuncula & Quintelaa in 2010 this has been reported as an invasive species being introduced through artificial cannals and water transfer.
