I've discovered a couple of hitch hiker clams (or some sort of bivalve, at least) sprouting from a patch of zoanthids. I've known they've been there a while but now they're large enough to be seen fairly well (at least in person). Currently a little larger than a 'fake fingernail' but initially did not exist (or were probably significantly smaller and obscured by polyps) when I purchased these zoanthids over two years ago. I used to think they were bare portions of the live rock until I saw them shut close.
No where near as glamorous or photosynthetic as the tridacna clams (maxima, crocea, deresa) that are sold, but interesting never the less as filter-feeder hitch hikers. There's actually two of them but I can only get a decent shot of the one on the left:

They close abruptly anytime one of my fish swims past them.
I don't dose phytoplankton or anything like that.
