something is eating my clams

[jab161]

My 155 has been running for two years. i had a 3 inch crocea for over a year, one morning the shell was completely cleaned out, a few months ago i bought a 2 inch crocea on friday, sunday morning it was cleaned out. i bought another 2 inch crocea at the last swap, last weekend it was cleaned out over night. but at the same time i havehd two derasas for a very long time and they are fine. any ideas what could be doing this?

You'll have to let us know what tank inhabitants you have. Some crabs will eat clams, some tangs/Morrish idols/ Regal angels will pick at them, a confused clown will try to host it and if you have a blenny or hawk that like the spot you placed the clam they might perch Fish that also eat clams are
Once your clam starts to die off all of the scavengers will finish the clam usually in one night depending on how many scavengers you have but please tell us what tank inhabitants you have.
Another clam enemy I know of is the whelk/conch but they are known to eat one clam a month . Hope this helps

also look up polyclad flatworm you will never see it with the lights on and it looks just like the clam's mantle

My guess is that your clams died, and were cleaned out by bristle worms and other scavengers. Clams can die without warning, and when they go, they disappear quickly.

Where did you place the clams? In the sand or on a piece of rock?
