Tenellus is a new genus, described by Birindelli (2014) to include, Nemadoras trimaculatus, N. leporhinus, N. ternetzi and the new species N. christinae all of course now in the Tenellus genera. The snout is constricted, narrowly compressed (gape very small); dorsal profile concave between tip of snout and posterior nares. Aquarium Care: Best kept in groups as they will not do well singularly. Avoid boisterous or aggressive tankmates as this is a shy species that will hide out during the day and appear for food at night under darkness. Provide a dimly lit tank with floating plants. Diet: Tubifex, Daphnia, Cyclops. Once settled in they will take frozen foods, flake and tablet foods. Etymology: Tenellus comes from the Latin tener, meaning delicate, in reference to the delicate appearance of those dorads. ternetzi is named in honour of Carl Ternetz.
