Hi Geoff

I don't presently have a way to test the water salinity, but I must be
somewhere in their happy zone. So far, I haven't observed any change in
body color. As for the fat lips, these guys still haven't shifted out of
2nd gear...very tranquil, and only less so during feeding times.

I really appreciate your help catching and tranferring this batch. I
learned some important tips that will save me many fish in the future. I
look forward to collecting with you again soon!
