if it does not move, i would probably suggest a sponge, filter feeder..Anybody else have any idea's?

if you mean the white stuff they would be colonial tunicates(sea squirts)...i was just looking at them in my marine bio lab. they are harmless and actually need supplemental feeding to survive. they filter feed so marine snow and phytoplankton would do.
