Tiny clams

[Reefaddict1979]

Well not really sure if they are clams. Shells look more like mussels

The question is I am starting to see tiny clams on my live rock maybe like 6. Any chance shellfish can reproduce in fish tank. Or did they just come in on the rock. Although rock has been in the tank over a year ?

Most likely a hitch hiker and yes I do have a few of them. They tend to move around a bit until they settle unto a permanent "home".

Oh they can move just like my flame scallop.
Because the one rock I found them on I am 100 precent sure there wasn’t a clam on it
