Recently I had a pink skunk clown fish in my tank die 
As soon as he died, I checked all the levels. The pH was right, ammonia and nitrite were 0 ppm, nitrate was something acceptably low like 10 ppm.
The clown seemed normal, got along well with his tankmates (a yellow damsel and a psuedo chromis), and ate well. I fed him every day, twice a day, until he started to spit food.
The only behavior out of the ordinary was his bowel movements. He didn't leave a piece of normal poo, but his butt just sort of exploded. There would be a big cloud of mess behind him when eating. I thought this was normal clown behavior at the time, but now that I have no explanation for his death I'm realizing maybe it was a clue to parasitic infection or some disease?
It's been a few months since the pink skunk clown died, and both of my other fish are alive and doing well.
