Christmass Tree worms (Spirobranchus giganteus)

[sharuq1]

I'm afraid all I have to go on here is my own experience, but maybe it might help.

We have ours under 4 pc lights (2 10k, 2 actinic), it's on the bottom of the tank and it (the porites that is) gets fed whenever I put little food in the jar (every 2 days to once a week depending on what the tank is looking like--usually brine shrimp eggs and nls pellets--the cleaner wrasse does a good job of making a mess so the eggs go all over the tank and feed the corals). I also just recently bought some reefroids from Elite in Calgary and am trying those out. (Just mix it up in some water and turkey baster it at whatever I want to feed with the skimmer off for a bit.) Polyp extension is great and it fluoresces a very nice green in the actinic light.

I think too much light would most likely burn the coral from what I have seen. (Last one I saw at mid-level in a store under mH had a lot of white on it-but then that could have been from something else too.)

Edit: From reading it seems they like water with more nutrients in it than many might have in their tanks. We tend to have a lot of diatoms on the glass as we have excess nutrients. We don't feed phyto, so I am betting the diatoms are the reason why the worms are alive. Never thought I would find a use for diatoms, but hey makes me feel better about my tank being a bit dirty
