So I was glueing up a bunch of pieces I had around my tank and I had to move my platygyra which my small Squamosa (about 3.5") was actually slightly attached to, to my surprise.
He then fell off it and all was well. I haven't noticed anything weird with him since.
Then this morning I went to feed the tank before the lights came on and I saw the thing in the attached photos.
I've seen other threads on here with something similar but they all look like the basal opening shape. This is like a straight perl, size and all.... with what looks like basal threads all over it.
I took it out and it's hard but also complys ever so slightly to firm pressure. Kinda like a perl.
Do clams ever make perls outside their shell? Also, is my clam doomed? He's been mega happy ever since I got him months ago from live aquaria and he wasn't by any means firmly removed from the platy. I just picked up the platy and notice the clam was attached just before it fell off about 1" up from the sand.
Thanks!
