there's a difference between stating the extra care requirement, and posting pictures of deep fried clams.
And yes, they also require calcium in the water too, in addition to filter feeding. Like snails, they have a shell to maintain.
And just because you personally would eat your pets, doesn't mean the OP wants to see it, nor do the rest of us. The next time we process a rabbit for the dinner table, shall I photograph the entire process and email it to you?
Also, just because your dog runs 5 miles a day, doesn't mean anything, just that it exercises. My dogs got free rein of 5 acres for at least half the day, but my dogs still had broken backs or legs if they ran into traffic.
