They look almost like some type of spore? Does anyone know what these are? There are 3 or 4 on one of my established live rocks. :worried:

The yellow thing in the middle looks to me like some kind of sponge.

I have several of those yellow sponges on a rock in my tank.

Will they grow, and or is there a way to feed them?
