New Derasa clam

[octasnow]

Hello I recently purchased a small derasa clam from my lfs and it has been in my tank for a little over a week. Ever since I put it in my tank ive noticed one end of the shells mantle dosent extend as far as the other end. Is this a normal occurrence or should I keep a closer eye on it? Besides that its very reactive to light and overall seems happy.

Looks familiar.

The clam looks normal to me.
Is there any Aiptasia, Vermitid or algae on the shell?

I looks happy, like my derasa, and there is white shell growth. If there is anything bothering them, you can brush them with a toothbrush and that will knock off any algae, etc. They close up for a while but open right back up soon after.

Thanks for the reply I appreciate it. That puts my mind at ease I still think I might need to try a few different spots on the sandbed because he keeps moving in little bits every day.

It’s completely normal for them to move around until they’re happy. I only intervene if they fall over on their side. If you have a general area, you want them to stay, you can put a flat rock under the sand and then sit them on top of the sand. They will attach their foot to the flat rock and stay in place a little better.
