What are these x 2 ?

Alright. This tank is a 20gallon Nuvo, about a month old and doing well. I see two things I can't identify. The first are these clear bubbles In a couple of the holes in the live rock. They look almost like a collection of little bubbles. Bubble algae? I already have a couple emerald crabs in there.

Second on my Tonga rock from my LFS, I see these little red things sprouting up. What are these?

Thanks!!!

New tank syndrome. The green stuff is most likely some kind of algae....possibly bubble...but can't tell from fuzzy picture. And the red stuff is most likely cyanobacteria (red/green algae), both of which are fairly common to a new tank. With water changes, this too will pass.

Those red things on the rock are Foraminiferans. (harmless) I'm not sure about the bubbles though. Can you get a closer shot of these or possibly circle them in the picture above? I'm having a hard time seeing these.

Maybe a really fuzzy picture of grape calpura?
