Correct me if I am wrong but edith and waterfall cr are a fair distance
away. I dont think its a fish below and a fish above example. I dont think
there would be any difference in the two in that example. Fish from above
would fall to the fish below keeping the two populations "together".
Edith cr exqusita's were the fish described as exqusita. I dont believe the
fish from waterfall were ever looked at in the same capacity.
