.... really? a 20G with a 150/w MH can produce enough phyto to keep a clam happy? and ar you guys talking about dosing phyto to the tank, or a phyto bath?

Clams feed on more than just phytoplankton. There's a huge list of things that have been found in the "bellies" of giant clams. I don't think Mr. Fatheree was trying to say that there was already a ton of phytoplankton in the water, but that there was plenty of food in general, much of it coming from fish waste.

Here's the biggest thing I got from him, though. There have been experiments to show that clams can survive (though not thrive) on light alone. They cannot, however, be sustained on food alone. If you can't meet their light requirements, all the phytoplankton in the world isn't going to keep them alive.

And incidentally, it appears to be bad advice to use the techniques of putting clams in bowls of phyto or placing some sort of column over them to pour the phyto into. If you dose phytoplankton, just dose it to the tank as you always do. The clam will get its share. These other methods are very stressful on the clam.

sure they can thrive without particulate matter. a lot of the clam farms only add ammonium nitrate to there clam race ways. most home aquariums will have plenty of nitrogen in the water for clams.

I think the quote sums up the areas of the book later about feeding. James Fathree writes alot about nutritent uptake, and he quotes all the reef masters saying really no extra food is needed in PROPER SYSTEMS. He still says "when in doubt whip it out" food that is. The essence of doubt lingers to me. I only trying to help.I know this subject has been debated for years. So continue on....

do clams bleach like corals? the clam was at my LFS for two full days under a single t5, plus however long in transit. i think its colors are getting darker. at first the brown part you speak of was a lighter brown.

oh sorry forgot to ask, i got him on the top of my rocks now, do they care about where on the rocks: flat spots? or just wherever? and is it ok if they are not standing straight up?

I have found that they will straighten up, them selves.

Yes they can bleach ,as for placement flatter is better. Just don't move repeatedly over short period of time,you can stress it to the point of disease or even death. Give it time between moves. This is a delicate creature.
The mantel is facing up open to recieve most amount of illumination,it's byssal opening (the fleshy underside) should be touching rock thats where it attaches.So the angle may not be perfectly facing up.
