Two of my asteria snails died today and when i went to take them out they seemed to have been eaten by either my other inverts or fish. I took the shells out and there was nothing left in them, so i then proceeded to toss the empty shells back into the tank. Now i have 4 shells just sitting on the sand. Should these be taken out? Or because they are so few they can sit without chaning the parameters?
