thanks for the replies. Here's the update:
- orange/black clown continued to look terrible...skinny, panting, and listing from time to time
- bagged him up and took him back to LFS
...they offered to "babysit" him for a bit; didn't think he had ich...no white spots visible, although I could have sworn I saw a couple of "salt/sugar" dots like y'all described the night before
- planning to continue to watch the larger orange clown to see how he does...still looks great for now
Also, despite the drama I couldn't resist when at LFS
and added a cleaner shrimp and an emerald crab to the crew.
Will post again an update on orange/black sickie after a few days of babysitting......
