Live rock spawning?

[unda_da_sea]

in the short while since i've had my tank i have seen 4 times small wiffs of what looks like white smoke coming off different pices of live rock. does anyone know what this is?

Dunno. Could be worms or pods clearing out a home.

Oh man I see that ALL the time!!! I think it must be worms of some sort. It looks cool but not sure it would foul up water quality though...

Could also be some sort of clam shutting quickly, also. Live rock doesn't spawn.
