You say "normally eats raw shrimp" ... what does that mean exactly? Are you giving feeders? Your water parameters are very important for diagnosing the problem. Things as simple as Sudden water temperature changes can cause these guys to go on a hunger strike...still wouldn't explain the color change being SOOO Drastic... With what you've told us so far I'm leaning towards parasite. More information would be needed but thats where my hunch lays
Although hi levels in any of the params will cause this as well with RTC's
