Thanks for the answers and the links. Somebody else suggested a dye job as well, and after looking through some of the pictures it appears that there were other dyed corals at the shop that day. The shop I bought it at was Ocean's Aquarium in Calgary. I'm not sure if they were aware that they were dyed, but I lost confidence in the shop based on other conversations I have had with their staff on a different subject.
Another lesson in not relying on the lfs for advice. Thanks again for the link- with that info and other advice I'm getting, hopefully I'll be able to bring him back to health.
