Does this clam look happy?

Excuse the blurry photos, I'm still not a very good aquarium photographer.

is the mantle contracting slightly at the lower right? It also looks as if it may be not opening as fully as it might- but hard to tell- is it getting hit by water flow? Has it been like this for awhile? Is it brand new in your tank?

Yeh, it's getting hit with some current, had it since last november.
Been trying different positions with it since then.

yeah, positioning them is a pain- wherever current flow is low and light is high. bet that's it- good luck-
