i just got a T. crocea last weekend. it looks like it is doing fine. expands fully. and will contract if it feels threatened. i put it on the sand upright but over the course of the week it has listed to the side. i decided to take a peak at it. when i picked it up to examine it i noticed that the bottom where i would assume the foot would be is a hole! do the clams have holes on their bottoms. am i worried about nothing. i thought they had a foot there.

i moved it up onto the rocks just in case. it is a 3-4" crocea. it is under 400w mh. with VHO actinics. i feed frozen plankton. i also have more feather dusters than brain cells, so there seems to be plenty of other plankton. all of my SPS are doing great.

Not only do Tridacna crocea clams have the largest byssus opening in relation to its shell length, but it is the smallest of all Tridacna species, making the opening appear even larger in this aspect. The shells are prolly the smoothest (heh, relative to the other giant clams), are one of the few species that can close completely, and are quite capable of boring well into limestone liverock where they are usually found (one of the littoral rubble species).

Ditto on the Fenner/Calfo book, Sue, VERY nice section on the clams.
