I'm looking at getting a fanworm or two, as my first corals.
I've read the Sabellidae family are of the most hardy, and don't require any particular lighting or really vigorous circulation (just a good amount).
But, 3 questions:-
1. My tank is 5 months old, but has good stable conditions. Will a fanworm do ok in my system, or should I wait for my tank to mature more?
2. What do the fanworms eat? Do they require special feeding?
3. I have some blue/red-legged hermit crabs and a fire shrimp. Will they try to eat the fanworm?
4. If I buy one that's attached to a piece of live rock or substrate, should I QT
it for a few days to make sure there's no ammonia etc. let off from the rock, before I put it in my main tank?
