dead... .
I was thinking that to. What is strange is that they have been in the same tank together for years. Not once have I seen the clown loaches act aggressive toward any other fish. They are very timid and usually hide if you stand close to the tank. It's true they might have started to nibble on the knife after he was looking bad. But I don't believe they caused him to die in the first place.It might have been the Clown Loaches. They chewed some of my Angelfish's top and bottom fins.
