I think your problem is probably a large bristle star they are nocturnal and in large tanks during the day are almost impossible to spot. I've heard so many bristle worms gone wild stories. I don't think it is a cone shell you would one small fish every three days and they are also hard to spot because they burrow during the day. It's not an octopus because you really should have seen them during the day once. Just do a stakeout at night. And if it is a cone shell becareful but I'd keep it.
