White cloud with black dots on base of coral. Help!

[crazytoyota21]

I care for a Saltwater tank at work and I am learning as I go. We have a Lawnmower Blenny, Foxface, Midas Blenny, tangs, clownfish, pajama cardinals, cleaner shrimp, snails, hermits, coral, etc... today I notice 2 new distinctions in the tank. Mind you Salinity is normal and Nitrate/Nitrite test shows safe levels. Everything seems fine except what you see in the pictures. On the base of the coral is a cloudy sack like with little black balls inside. The second is the solid white on the side of the other coral and rock. Any insight would be greatly appreciated.

It might be a sponge, I can’t really tell

Do you have snails? Is it stringy? Have you touched it with something? Is it soft? Could it be some kind of eggs?? See if you can notice any movement .
