Aquarium Care: This is indeed a beautifully marked catfish but in the aquarium you may not see too much of its beauty as it can be crepuscular in nature and will need hiding places to make it feel more secure and happy in its surroundings. Can be kept in a community tank but may eat very small fish at night such as the fry of livebearers, but basically a good addition to the larger tank set up. Diet: Will take most prepared foods such as frozen bloodworm, tablet and flake food. Better to feed at night after lights out, but once settled in tank will forage for food in low light conditions. Etymology: The genus name Liosomadorus: From the Greek leios, meaning smooth; soma; meaning body and Doras (a genus of doradid catfishes); in reference to the lack of bony plates on the body (when the genus was described as a doradid). The specific name: oncinus: named after the Jaguar cat, Panthera onca, because of its markings.
