Do you mind if I ask where you read this? Chocolate chip stars are generally predatory, though they have the ability to eat algae when needed. While they will eat algae to some degree, they are in no way considered grazers like this (though they are often 'grazing' on the critters that are eating the algae, so it may appear they are going after the algae). Urchins eat corraline algae, but not, in my experience, chocolate chip stars which are on the lookout for meatier stuff. It is possible, for sure, but that is not what most people worry about and I would encourage feeding it meatier things. They will eat all manner of snails, clams, corals etc though.
