I picked up a new clam over the weekend. It is an aquacultured maxima. I got it home and dip a 1 hour drip acclimation before moving it into my coral quarantine tank. I got a few green flat worms off of it, but haven't seen any since. I did a flatworm exit round just now and nothing came off. Might have just been those few I suppose.

The clam seems to be gaping to me, but I'm not sure if perhaps my interpretation of gaping is wrong.

This first picture is an aquacultured maxima I've had for probably 4 years. It has always looked like this.

This is the new clam, (sorry for all the blue). Seems maybe a bit worse? What is weird with this one is that I can see straight through to the sand under the clam through the mouth. It has put down strands and attached itself to a rock buried under it in the sand.

Can't say for certain. I haven't done a par test on this tank. I'm running an XR15 G4 Pro at 50% ~14" above the tank.

EDIT: The new clam was in an outdoor greenhouse, so probably getting a lot more light than it current is.
 
Let the clam tell you all that you need to know - it knows better than a PAR meter. :) Below are some of the clams in my nursery where they are getting a ton of light... look how they are open, but not stretched out. I would go with "it needs more light." It cannot hurt since you cannot really over light a clam. I would move it up or get more panels or T5s.

 
Thanks. I guess that could be it. This is a trusted source but it was on the small side. I really want a derasa like I had before so maybe I’ll just opt for that instead of another maxima.
