I'm trying to figure these guys out (should post a few pictures). I purchased two groups - one from aquaimport that had red tails and one from wetspot which have black tail. Visually they look very fragile with the bodies waving in and out (other species have a more rigid body - i mean the actual body of the fish seem to wave on the eques). Also while description suggest they would hate current or expect very slow current at least one group like to pile up right in front of the flow bar - while a few will get behind the flow bar (small space between the glass and flow bar where the suction cups are - which is more dead space with regards to flow); many will get just in front of the flow bar.
The other thing of course is these seem to be insect hunters rarely leaving the top area with the mouths at the top - the only other species of nannostomus i own that exclusively remain at the top at the epesi with all other species spending a little to lot of time mid to lower level such as margarita.
