Bulbs are 10,000K and I Keep T5 the actinics off otherwise the anemones wander.
I get fresh never frozen scallops from the grocery store. Make sure you get the "no water added" ones. They use some chemical to make the water added ones soak up moisture and I don't know if it is bad for anemones or not. The frozen are fine too, but my anemones seem to have less of a feeding response to them once they have been frozen. I use fresh raw grocery store shrimp too and leave a bit of the flexible shell on the swimmeretts for healthy larger anemones. I have even just dropped a whole shelled shrimp in on occasion. We also will give the anemones a small bit of raw fish with the scales attached if we have tuna or other ocean fish. I never see a big response to fish, but it is much better with the scales on that without.
All of this has worked for me, but I can't say whether or not it is better than what anyone else does. There is some anecdotal evidence that spoiled food can be a big problem for magnificas which is why I stay away from anything that I wouldn't eat myself (with the exception of some mysis which I hear is lovely with a little lemon- garlic butter.)
Remember, with these guys, we really don't have enough information to know what the best thing to do with them is. We are always quick to attribute reasons for success or failure when we really don't know cause and effect.
