I was repositioning a few corals just a little bit ago and bumped my baby Crocea clam causing it to either release its foot or be torn from the rock it was on. I'm not sure whether it tore its foot entirely or just took some temporary damage. I know they're foot is very sensitive and can cause them to die if it is damaged too severely, however, I've never seen this happen to one personally so I'm not sure what I'm looking at here. The clam is about an inch and a quarter from mantle tip to mantle tip and its been inching its way down some live rock lately which leads me to believe it wasn't well attached in the first place. The spot on the rock where it was attached now has some mucous and a piece of flesh about the size of a bb on it. I checked the bottom of the clam and the foot (or what's left of it) was retracted and the clam is beginning to open up on the sandbed now. I bumped it pretty gently but I'm just not sure how much they can take before the damage becomes irreperable. All help appreciated.
