i have a 5-6 inch crocea under a 250 watt 10 k halide. i have placd him in the rocks he flips out and lands on his side. i have placed him on the bottom he flips over on his side. hes been all over my tank blowing sand im going to leave him on his side and see what happens. is this ok to do leaving him on his side on the bottom.
i hate my clam

Please don't leave him on his side.
He is telling you he hasn't or you haven't found the right place for him. Check your current, is something picking at him? T. Crocea need instense lighting more so than T. Squamosa. The lack of light will make them slowly fade as the instense lighting is needed for there symbiotic algae in there mantles.
I have some great links on my site by Daniel Knop, author of the book, "Giant Clams"
Hope this helps.]

As others have said: Your clam is trying to find a happy place. Croceas in nature attach themselves to solid surfaces so you're unlikely to have success leaving the clam on the sand. Also, croceas are high light clams relative to squamosa, derasa, and a couple of other clam species. Try to find a home closer to the light rather than farther away from it.
Perhaps the clam is unhappy with the surface of the rock on which it has been placed. Is the surface smooth, or does it have jagged irregularities? I've had good success with croceas on smooth rock surfaces. Another crocea trick is to get half of a clam shell that is relatively flat and use it as a base for the crocea. Rest the crocea on the inner (smooth) portion of the shell and the crocea will probably attach itself quickly.
Try feeding DT's (live nanoplankton)to the tank. This is a good food source for clams in addition. I had very good clam growth rates when I was running reactors to maintain a stable Ca/Dkh and 250W MH's or higher. I experienced excellent growth when I started feeding DT's. For the record, my observation does not represent good science. I simpy measured the growth of the clam shells each month using a plastic ruler inserted into the tank.
Finally, I've observed some amazing color changes in croceas as they grow, specifically when they start out as small 1-2" specimens. You might be in for some pleasant color surprises!
Good luck.

I hate my clam. You should say that out loud a few times before you post it.
Such emotion.
Anyway, I have two croceas and both over a year old. Both are happy in the sand. One attached through the substrate to the glass bottom of the tank. The other never attached to anything. I tried to mount one in the rocks, but it would always fall within a few days so I quit trying to put it in the rocks in fear that the fall could eventually injure the clam.
They have both grown maybe 1/2 to 3/4 of an inch.
My lighting was originally 4-110W VHO's. About a month ago I upgraded to 2-175W 10K's with 2-110W VHO actinics. That didn't seem to have any effect on the clams. BTW, my tank is a 75.
Good luck!

andy. ill be happy to trade you the clam for your mr-3 skimmer or your cr-4 reactor, its up to you, either one suits me. let me know when i can come buy and swap. buy the way i got my stand built for the 350. i would sure like some input from you on where to place my bulkheads and plumbing for the sump and maybe a closed loop system.
