qatarissun, from experience I'd say that if you can't see the cleaner fish then it's definitely dead and most probably eaten.
If by cleaner fish you means the ones that suck onto the side of the tank and clean the algae of, I had a couple of these and they were disliked by all the other fish. It seems that they're not the most popular of tank-mates!
Fish do sometimes find a hidden spot die in - I've often found corpses tangled in the base of plants before. And trust me that size doesn't matter when it comes to eating - I've seen tiny tetras taking bites out of the corpse of a much larger fish.
A couple of times I've had a fish completely disappear, and the obvious conclusion is that it's fed the other inhabitants of the tank.
Once a fish starts looking poorly it's best to remove it from the main tank immediately, as the other fish will prey on it. Also, if the other fish do eat it they risk catching any diseases it had.
