The fish we caught at the Running River were all as identical as you would
find possible to believe - minimal variation and a different body shape
even whereas those from "The vallry of the Lagoons" were extremely variable
and more of the typical Splendida shape and markiongs with variation
especially in the black and gold lines and spangling.

Please remind me in a couple of weeks Peter and will be happy to oblige

Hopefully none will die for a while - Steve Brooks has hopes of breeding
them in the future and as they seem destined to be in the Macquaria genus
the well-known hormone induction techniques should be applicable.

BTW Peter the Mogurndas from there were different too - small and quite
colourful but numerous very small red dots all over the sides and even some
naturally occurring scolioses in them

Yeah, Randy Roy is still crowing but unlike his namesake he doesn't like to
get up early unless there is a point to prove ;-)
