need advice on 9" durasa

[sohoal tang]

I just bought a 9" durasa...large clam...gorgeous....

I will be putting him under 2 x 175 metal halides in a 90
gallon 48" long tank..... along with 2 x 40watt actinic NO bulbs..

WILL this be enough light do you think?
andddd....what do you recommend for care of this animal?

Thanks
Tim

p.s. I have a crocea on the bottom now doing excellent
and an ultra crocea 2/3 up from the bottom doing super...
I feed them phytoplankton...IS THAT ENOUGH? The stuff
in the bottle....green in colour and NOT CHEAP....

That is plenty of light for the Deresa.He will do fine on the bottom.DT's is the preferred food for clams,but I am also using Knopp KoralVit F just for variety.
