I have two more pics! The previous owner had them for more than a year 1 1/2 years and the big one got even bigger! The smaller one didn't grow much but appear to be very healthy. :-)
Thanks experts!

Here's the small one:

The first pic is a squamosa and the second one looks like a gold maxima.

That was my first thought but the mantle pattern looks more like a gold max pattern than a crocea. You may be right. Uhm, James, can you take pic of the shell of the second clam? Thanks

without a better pic I would say Squamosa and Maxima

Squamosa, crocea.

Thanks all!
It looks like the small clam is a crocea.
The shell is covered in algae... It's hard to see, but the shell is identical to the T. Crocea I have.
I want to move this little clam in the middle, but it glued itself to the glass bottom pretty well. I take it the clam likes it there, so I won't disturb it.
Does anyone have any shell pics of a Maxima?

Here is a shell view of a Maxima
You can see the shape is a bit skewed to one side.

for me, the key to telling the small one is a crocea is not the shell or the color, but the shape of the mantle. look at a bunch and you'll see what i mean.

I think the second one is a maxima based on the color and shape of the mantle. But a closer pic of the shell will help with confirmation.

Yeah,I can always tell a clam by the mantle shape.

A guess at best would be that they are squamosa's. A picture of the shell as well will provide a lot more information in the determination.

Dustin: Nice looking clams.
Newbie question... How do you post an image that shows up automatically (no clicking required?). I can upload my own pictures to my provider.
Thanks,
James

A picture of the shell (which I dont have) would only make it harder! Those clams are hybrids. Squamosa x Maxima
It can be tricky identifying clams from the mantle or the shell, since they hybridize quite readily.

Dustin's right, clams do hybridize easily. Telling a Crocea from a Maxima via the shell is not a good idea. Look at the hydial sensor arrangements, the eyes - little bumps on the mantle.
James' small clam is a hybrid between a Crocea and Maxima. It exhibit hydial sensors in both a linear line around the periphery (Maxima) AND has them randomly distributed across the mantle (Crocea).
