moving a crocea

[muse12]

I have a crocea clam that is attached to a rock with the little threads on the bottom side of the clam. Is it ok to move the clam (aka break the threads) ? Or is it bad to break the threads? I do not need to move the clam, but it would be better for my tank if I could.

It's not the threads you really need to worry about but the bysal gland. It's like a fleshy "foot" used to solidly attach the clam to hard surfaces. If torn or damaged, the clam most times will not survive.

I would advise against it, too risky unless you very sure of the foot.

Cheers

Are croceas able to live in the sand? or do they have to be attached to a rock?

They do best when attached to something. You don't necessarily need to place them on your rockwork though. For ease of movement, you can place them on a small flat rock or the ½ shell of another bivalve. A well cleaned oyster shell or clam will do. That way the live clam is happily attached and you have the freedom to move it as needed.
