Re: N. rachovii
Hi all,
strange coincidence that this subject pops up know cos I just had the
atlas out checking on the various locations of RAC I have. Huber lists
the type location for Rac as 19.8S 32.8E which on my map puts it
somewhere north of a town/village called Dombe. I'm assuming that this
is the RAC we all know and love, and is the "aquarium strain" pictured
in many aquarium texts. This however does not correspond with what Dr.
Watters has just stated, so is the type locality different from the old
aq strain? Could you please let me know the grid refs for the '91 & aq
strain.
TIA,
Guy.
