Tenellus is a new genus, described by Birindelli (2014) to include, Nemadoras trimaculatus, N. leporhinus, N. ternetzi and the new species N. christinae. 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.
