I just added three small feather dusters to my tank, along with a candy-cane coral. I have a couple of questions:
1) Do FD's need a tight crevice to lodge in, or is a fairly big crevice okay? I mean, they seem to have some kind of foot or pad, but does it need to be planted in something particular? The live rock I've got has several great crevices which I put the FD's in, but I'm not sure if they need more of a tight home or do well just about anywhere.
2) I thought the candy-cane's were a hard coral, but now see that they have some sort of tentacle system. So far I only see that at night when the tank lights are out. Is this normal behavior?
What do these guys eat? Is it sufficient to just let them skim the water for nutrients or do I need to supplement them? I know the LFS recommended that I supplement my polyps with a phytoplankton liquid about once a week (which, btw, the cleaner shrimp smells and comes *running* every time this stuff hits the water), but do other corals and softies require supplements?
BTW, this is a new tank (as you have probably surmised).
30g, reef, no swimmers yet.
Also, what is a good reference for these kinds of questions? Any books that you can recommend for behavior, applicability, growth, etc., requirements?
thanks,
bruce
