It's about the same as any other clam, high lighting, good water quality, yadda yadda. They're a slower growing clam, but still a giant species. Not as common to see in the home aquarium, but really not any different in care level than the Tridacna clams.
It's one of the sand dwelling clams.
The notable difference with them is that the mantle does not extend past the edges of the shell like other clams, such as the Maxima, do.
