Can anybody identify these clams they are alive and I’ve had them for about a year. They came in on a Zoa colony. Will they get bigger and turn out to be kool or anything? They are small enough my copper and can’t get inside them lol
Pics under white light from a variety of angles (including ones that show the mouth and hinge if possible) would help with an ID - that said, from the pic provided, maybe a mussel species?
Either way, I wouldn't expect them to get too much bigger.
