Clam help

I just bought my first clam on monday and i dont think i have enough lighting for it. My lfs said i should have no problem keeping it under the lighting i have, i have bought all my equiptment from them and i dont know why the would sell it to me if i didnt have enough lighting. Right now i have a coralife fixture with 2 96w, a 10000k day and a actinic 03, also 2 led moonlights. My tank is a 38g, 36x12x20, the clam is a crocea an he is about 12" from the light. From what i read here and on clamdirect.com the crocea is the most light needed and requires a MH for sure. Maybe my lfs doesnt know what they are talking about or maybe they are just trying to sell a clam . Im not sure but they have been really good to me about everything else so i have doubt that they would do that. Anyways im just woundering if i will be ok with what i have or if there is any kind of MH light i could add to what i already have without replacing everything. Here is a pic of the clam although its only been about a day since ive had him.
Thanks

Hi,
Thanks Om3n i will try and find a MH that i can use with the lights i already got. The clam is about 3in or so and i have been feeding live phytoplanktons. Anymore feedback would be great. I am going over to my lfs today and i will talk to them some more about it too.
Thanks again

hey,
Im deffinatly going to upgrade to MH. How does this light look http://www.marinedepot.com/aquarium_lighting_metal_halide_coralife_aqualight_pro.asp?CartId= ? And how long do you think my clam will last with the light i have till i get the new one?
Thanks

cool thanks scribbles. I think im gunna go with the coralife just for the fact that my lfs has them on special. is a 150 watts enough for the halide? or will i need more then that, like 250? thanks again for the help.
