The whole discussion is exactly about who eats who... :-)

So it is important to notice if crabs eat dead/sick snails
or if they are able to catch/hunt down healthy snail...
In the meaning of a word "hunting" we are used to when
talking about, for example, eagle grabbing a rabbit...

For an eagle it does not relly matter if a rabbit is sick,
if it can see it, it will take it when hungry...
This behaviour I call hunting. With crabs/hermits the prey
animal has to be originaly very weak/sick or dead already
to became prey. That is why they are called "cleaning crew".

They do not decimate healthy population of snails, rather
pick the dead/sick ones as food. That is my working theory :-)
And current reports on the internet are not describing any
hunting behaviour, rather people see crabs eating dead meat
and ASSUME what must have happened before... :-)))

Agreed..
The ones we are talking about are not hunters.
Nor aggressive or large enough to be.

They are probably hunters in the regular meaning, but they
regular prey are worms, crustaceans - anything very small
they could grab with one reach of a claw. Dead/sick snail
is an opportunity they do not pass, but they usually do
not waste their life energy to hunt larger healthy animals.
At least this is my observation in my tanks, with dozens
if not hundreds of several different hermits and crabs.

When I had a fish only tank 5 years ago (29 gal)
I had a large common hermit crab.
The one with the hairy legs...mean SOB
This guy I believe to be a hunter. He would go after everything.
My damsels used to whack him with their tails.
So to keep it REAL interesting I put 2 in the same tank.
I know, that was a dark time in my life : )

Oh the fights were incredible.

Did they really hurt each other (broken limbs, etc.)
or just wrestle to establish who is The Leader in the tank? ;-)

Oh hell no, they ended up fighting to the death !
They would start at either end of the tank banging their shells against the
glass, like a dance.
Then they would walk over to each other and start pinching and pulling, it
was a pretty even match
for a few months. They would fight, retreat and repeat.
I came home one day and the one crab was sitting at the top of a rock
completely out of it's shell. Shortly after the other crab whacked him.
Nasty SOB's. Both were 2+ inches with lots of hair and girth.

I'll tell you what, these crabs can keep a tank spotless.
Ferocious appetite, better than the reef safe crabs.
Another DeathCo...I mean Petco purchase.
