I picked up a very nice Squamosa clam from the LFS a couple of weeks ago after having good success with a Crocea clam. The Crocea has attached to a frag disk in the sand on the bottom of the tank and appears to be very happy there. I am running 2 X 250 watt MHs lights w/ 20K temp bulbs. Anyway, the Squamosa clam was attached to an Oyster shell at the LFS and so I left him that way as I should have and placed him on the sandbed of my tank. The clam has been doing well, but two days ago I woke up to find he had detached himself from the oyster shell and moved into the sand nearby. Last night I moved him back to the original location he was in and this time buried the oyster shell with a little sand over it before placing the clam gently back over it. Is it normal for Squamosas to move like this? He moved back to the spot he liked again, so should I just bury a frag plug or shell under the spot he likes and let him be so he won't attached to the bottom glass? Thanks for any suggestions. He is opening fully and quickly closes when a shadow comes over him, so the clam appears to be healthy.
