Beautiful!
Curious if you used something to secure it in place? It appears to be boring into the rock (just like in nature) and I've always wanted to see captive clams working down into the rocks on a tank.
Nope! So that rock it's on was a fragment of some leftover Marco rock I had laying around. This particular rock looked like a drill had gone through it, so I chiseled that part out so it made a sort of canoe for the clam to rest in (like a halfpipe). It took about 3 days for the clam to start attaching, and about 6 for it to be secure.
I'd love to have clams boring into rock in my tank! I've pondered a lot about how to make it happen. I think I could do it with a crocea. My thoughts are to create a small divot in the rock, just big enough for the clam to open up and have a little room to grow. Clams should have no problem boring into marco rock. I may give this a try.
