Suprise....Mollusks Hitcher!

I was at a LFS saturday and picked up a fist sized "rock with mushrooms". After I got it home I was noticing that of the rock under the shrooms was made up of oyster/clam shells. Well today as I was checking out my new shrooms I noticed something. One of the "shells" was not only open but it had a syphon extended from it! As I pressed my nose up to the glass it quickly snapped shut. So I grabbed the camera and waited for it to open back up.....


and I give you.....

Mushrooms on clam.......

I had a couple of those before. However since they are strictly filter feeders they usually perish quite quickly in most tanks. All of mine have always died within a couple of months

i have some they have been in my tank for over a year

Here's mine. Been in my tank for more than 6 months and has grown since.

note the oysters beneath and to the lower right side of the clam. They seem to be thriving so far.

mushrooms on clam...sounds like the title of a piece of modern art!

ive got a few hitchiking clams in my tank, especially ones that bore into the LR and have red mantles. They form a nickel size hole in the LR where they reside that can go back several inches
