AFAIK lighting is not really that important...but they do need to be fed phytoplankton (I would go with a live source like TekCat said). Many starve to death in tanks with innapropriate food sources.
If it is starving...you will know it when the worm sheds its crown and regrows another one...and if it still doesn't get enough to eat it will again shed its crown until it dies.
They are said to do better in tanks with healthy sand beds.
Thanks guys, I will go for a DSB and do regular dose of cultured plankton. Will have to laook at the diy section again for the thread for culturing those.... any idea about the links??
FYI This is what Dr. Ron said about how to feed (and not feed) them:
"Target feeding is a good way to starve these animals. When the food density is too high, they retract and shut down. They need a fair bit of phytoplankton or phytoplankton-sized particulate foods in the water column at all times. You probably should be feeding it as much on a daily basis as you would feed a fish of the same weight (excluding the tube)."
Hmm...I'm not sure.
When I had PCs I always had the white (usually 10000K) and the blue (50/50) with corals but I THINK that double 6700K or double 10000K would be fine.
As far as what to keep...that depends on the depth of the tank (PCs do not penetrate as deep as MHs) and where certain specimens will be placed. Higher light loving corals would obviously need to be placed higher and lower light corals could be placed lower in the tank, depending on how deep the tank is. If the tank is deep then even lower light corals would need to be placed closer to the surface.
