What's happening to my Tridacna?

[94Rudolph]

In a short time, there are many pits in the mantle. what is it? I didn't see any snail.

Looks like a normal tridacna crocea to me, nothing to worry about. The mantle typically has small nodules and also pinhole size eyes. Looks healthy IMO

I have on Derasa and one Blue Maxima. Never saw anything like that at shows or stores. Keep searching, good luck.

Looks.likes someones nipping on him. Watch your fish.

Looks perfectly healthy to me. My clam looks similar with nodules as well....

 

[reef lover]

Not the nodules...the divets/ dents that look like bite marks...

That can be normal in some mantles. IMO if it was was being nipped the mantle would be retracted
