I have a Crocea that has been in my tank for a little over a month now sitting on a ledge. I gave him a nice little piece of LR to sink his filaments into.

this morning when i woke up and took a peek at the tank before running into work, I noticed a white 'fiberous' column where the clam used to be, the clam itself had moved into the sand, half burried, but mantle fully extended and looking very healthy.

wondering if he just decided he wanted a change of pace?

I am going to leave it where it is.
