Clam/mollusk ID - was bought as a piece of live rock. (Pictures)

[xyra]

Hi,

I'm new to posting on the forum so hope i've posted this in the right place, and have been reading for a while. I've just been setting up my first saltwater tank (24x12x15) after 12 or so years of keeping freshwater. Planning a much bigger system in 6 months or so.

About a week ago I purchased some live rock from a LFS (the third batch to go in the tank). One piece looked on closer inspection like a dead clam of some sort nicely covered in algae etc.

A few days ago I looked into the tank and the clam thing is open and alive.

Any ideas on what it is and what I need to do to care for it?

This is a fairly new tank so the brown algae on the substrate is because of that - it has almost completely gone now. Parameters are pH 8.0, nitrIte 0, ammonia 0, nitrAte 20ppm. 110 watts of Power compact lighting.

Thanks for any help!

Wow that's cool.
It doesn't look to be photosynthetic..so it will porbably need lots of nutrients/filter food to survive...but don't take my word for it...

I would ask Dr. Ron if he could ID it and give you some info on it..he loves IDing weird stuff () : )

i had a little clam attached to my live rock as well - after two years it is still there, about tripled in size. i've been meaning to take a picture of mine and have it identifiied as well. i haven't done anything clam specific to maintain it, seems happy with whatever leftovers it receives from feeding my two green clown gobies.
