Crocea Moved

[rdnyva]

I have had this 3 inch Crocea for about a year. It is/was attached to a piece of LR. About 6 months ago I moved it a little higher up on the rocks next to another Crocea about the same size. All was well until this morning when I found it on the sandbed. There where no bysall threads visible. I'm assuming the clam detached itself. I'm wondering why after doing so well for the past 6 months it would do this. I placed it back up on the original LR in the hope it reattaches itself. It has opened nicley and looks as it normally does. Any suggestions/recommendations/observations? Anything I should be on the lookout for? Thanks in advance.

nipping is the only thing that comes to mind. that can cert'ly start suddenly.

My Crocea just moved after several months. I think it was getting a little crowded by my Max. I just put it on the sand with a piece of rock under it. I will move it up when it reattaches itself.

I don't think nippping is the problem. The only fish in the tank are 2 tangs, a yellow and a powder blue, a six line wrasse, a royal gramma and 2 small ocellaris clowns. The PB has been in the tank for 3 months, all the others more than 2 years.

about 20 blue leg hermits, some nassarius and cerith snails, 2 skunk cleaner shrimp and a cuke. They have been in there for a long time, nothing added recently.
