It is pretty cool in any case. It is also cool that it has stayed alive for a year.

Thank you, I sincerely appreciate that. I’ve had a flame scallop for about the same amount of time and I’ve become particularly attached to it which is why I try to keep up with the phyto. Hopefully that’s what is keeping this guy alive and I can keep it going

I’ll look up zig zag clam as well DSC Reef

Anytime. I'm pretty sure it's not a photosynthetic tridacna so keep up with the phyto.
Looks like the ones that incrust into the reefs. Bore clam? I just watched a YouTube last week on them. They dig in the reef abs it grows around them. Two main types, ones on the sand bed and ones in the rocks.

Look up zig zag clam (cristagalli) that might be what you have. It's a type of stationary suspension feeder.

It looks like a zigzag, and I’m too lazy to try and look up bivalves from Mexico. If it was a reef boring clam I think the snail would have perished already.
If you glue the snail to the reef, I think you should put a camera on the tank and record the slow death of the host snail and the subsequent demise of the bivalves as the snail carcass rots beneath them. Won’t that make a fine video?

Otherwise letting things proceed as they have with plankton additions would seem to be a kinder and successful approach. :)

I believe your thinking of tridacna

I've had lots of bivalves come in as hitch hikers on frags but never on snails. All the ones I've seen had smooth edged shells, not the scalloped edges these have. In one of the pictures the shape looks more like a scallop?

I know this is an old thread but I was curious on the outcome? Did you ever figure out what it is? I have the exact same thing growing on 2 of my snails
