Pretty small clam. IMO, I feel it's better to get a clam that is at least 3 inches.
It is quite possible for a worm, crab or snail to attack the byssal opening of a clam and eat it inside out. That's why it's good to place it on a piece of rock so that it can attach itself to the rock and the byssal opening is not easily attacked.
