yes, the more I have been looking the more I've seen of some sort of outbreak of brook. These guys were TR at ORA and shipped through saltwaterfish.com. I'm assuming this is where they became infected as they keep WC fish as well although I'm not sure of the tank arrangement.
Noon update:
small one: yesterday did not eat. Today accepted selcon soaked frozen brine shrimp and flake formula 1. Stringy white poop observed 25 min later. Breathing very rapidly and now looks laboring. Swimming movement has increased but no erratic behavior. dorsal fin is clamped down, all other fins look normal. small discoloration at the tail just behind most caudal stripe. Swimming w/in .5" of the bottom.
large one: still not taking food. breathing seems normal, no erratic behavior. has same discoloration at the tail. Swimming higher in water column than small one (3" off bottom)
I will continue to monitor this spot on both of their tails. I can't tell if there is mechanical damage or if it is the beginning of a disease sign.

no other tests performed, will take sample of water to work for accurate testing (we're talking ppt, its nice to work at a research facility).
Thank you so much pipedream for following along and offering advice, I know this is old hat to many of you but as a newb I'd like to thank you all and you are such a valuable resource to us all. Keep up the good work!
