Plate Coral spinning a web?

[Fastrabbit]

I recently set up a 45 gallon diamond tank with sump and have finally gotten my first coral, a medium sized green long-tentacle plate coral. I put him in last night and today something looking like a cobweb was coming off of it. Is this something to be concerned about? What is it?

i uploaded photos, but this site won't let me put them here until I have 20 posts...so here is where the pic is:

info about the tank:
45 gallon diamond shaped tank
back wall is overflow down to sump under the tank...has blue filter pad and some live rock rubble...protein skimmer then rio 2500 pumping water up y-pipe to 2 returns in the tank
250w 14k metal halide
2 blue led moonlights

info about the setup:
60-70lbs live fiji rock, cured in the tank for 1.5 months
40 lbs argonite "live" sand
all readings on strip are good; salinity .22, temp 80ish

inhabitants:
10 snails (down to 8 due to hermit crab eating 1 and starfish eating 1)
10 dwarf hermit crabs
2 nassarisus(sp?) snails under the sand
2 small red starfish
2 cleaner shrimp

add lots more coral all over the tank
1 pair of clowns

sounds like the "war jelly" goo that corals put out when they are PO'ed

[Fastrabbit]

is it PO'd from being moved from LFS to my tank? or something else? the hermits and snails don't seem to be messing with it...

the web did recently come off and float to the top of the tank

is there anything I should do or is it 'normal' to have this happen?

[Fastrabbit]

also, it's definitely white and web-like, not brown and jelly-like

nothing to worry about unless it doesn't go away once the polyp expands. that coral would be happier in the sand i think.

Horrible survivability rates for those corals in captivity, especially in a new tank.

Can you see a red or brown tube on the side of the coral by chance? It looks like it could be from a larger vermitid snail.
