Maxima clam Killed by Urchin?

My 2" maxima clam was bulldozed by something in my tank. The foot was left behind attached to the rock and the clam was loose but otherwise seemed fine. Prior, I had the clam for about 3 months and it seemed healthy.
I hoped that the foot would grow back but over the next 2 weeks it opened up wider and wider and stayed open 24/7 gasping. Slowly it got sicker and finally died.
I assume that the culprit was my shortspine urchin but I'd like to hear other explanations including that the clam was sick if that's possible.

I just got a clam myself about 1-month ago and I am learning a lot about them.

I do not remember the article, but basically they say a clam will "look great" right up to the time it "does not". It is a complicated animal with internal organs inside that shell that it won't show signs until it croaks. I do remember the article says to look at the tip of its shell where it meets the mantle, there should be slight white band indicating that is growing (as opposed to dying by doing nothing).

These are the reasons:

Water parameters, they really do not like elevated magnesium or inconsistent salinity levels.
Did you add phytoplankton into the tank, at 2" that is on the borderline lower-end of being able to self-sustain itself just through photosynthesis alone.
Was it getting sufficient light....everything I read cites you need to give them maximum light, as much as possible.

IMO, a healthy clam wil be able to "hunker down" and won't get dislodged by an urchin.

FWIW,
