It is unlikely, but it is certainly not impossible. Ich, for example, goes through multiple physical changes during it's life cycle. One of the stages is a cecile "pod-like" stage where they sit attached to rocks/corals/shells while they mature to the free-swiming stage.
, drip aclimate, then FW
dip before placing in your display tank. one thing you could do, is with a soft tooth brush go over any rocks, shells etc (but not corals, you don't want to damage their polyps) before placing in your main tank. It's not "necessary" but if you want that one extra level of comfort, you at least know you tried.
