I introduced a 2" maxima to my tank on Thursday (9/12/02).It was sold to me as tank raised, and from a fairly reputable source. It came from under (2) 175w MHs and looked fine, facing straight up from the sandbed; however, it was only in this holding tank for a couple of days before I aquired it. Before this, I believe it was under VHOs in another holding tank, but I don't know for how long, and I don't know what light it was originally raised under. I put it under my 250 w MH, in the sand, and by saturday it had used it's foot to push itself onto its side. This is my first clam so I don't know if this is normal behavior. Might this be a reaction to too much of an increase in light? I'm not sure if I want to put it through the stress of being frequently moved around the tank. Might this simply be the clam getting fed up with being constantly jumped from tank to tank and never having the opportunity to adjust? If so, what would be the appropriate course of action (duh, don't move it again)?
