    So this came on a zoa colony rock i got from petco. Assumed it was dead and picked it off but it opened up so i guess its alive.
    Im thinking its a cockle?

    Are they useful at all or should i toss it? Was told it sucks up alot of calcium

    It would be good to keep as he will clean the tank but some of your fish might attack him. But if he dies he will be stinky (like all bivalve’s) and cause ammonia spikes sometimes he can die when he is buried so if you have ammonia spikes look in the gravel
