What are these white things all over everything?

[Kshupe]

These little white creatures are all over EVERYTHING in my tank- glass, heater, live rock, decorations... Some are small and some are large. They don't move from what I can tell and the larger ones seem to have some small antennae... Any idea? They appeared in a matter of a week it seems.

They seem too big to be pods though... Can they grow that large? If they are pods, wonderful, I've been wanting a mandarin fish!

Still blurry Haha but look to be pods to me I have the same thing all over my tank... Maybe someone else will chime in.

Anyone else think it could be something besides pods?
