Tenellus is a new
genus, described by Birindelli (2014) to include,
leporhinus, N. ternetzi and the new
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. ternetzi
is named in honour of Carl Ternetz.
