I got a nice new mushroom rock a few days ago and couldn't believe my eyes when I saw the whole top of the rock move suddenly!!! very spooooky! On closer inspection I saw what I assume must be two or more bivalves (I can only assume oysters??) in the top part of the rock! If they weren't opening and closing slightly I wouldn't know that they were not actual rock. They only open up to about 1mm (less than 1/8 inch)
So I'd really like to know if they are oysters and if so how can I keep them alive? Both for their own sake and because they're quite large and I'm afraid they'll pollute the tank if they die.....
This is the whole rock:
This a close-up of the top of the rock (also baby brittle star legs in front of open oyster)
the next two show the oysters outlined in red and a side view of the big oyster with open shell outlined

I took a pic and it was labeled a jewelbox oyster. I have been feeding the tank phtyo to keep it alive. So far, so good. I was also told that they don't last long in the hobbyist tank but if, when, it does die, it wouldn't cause much of an ammonia spike at all.
