Any ideas as to what it is and whether it's good or not?

 I had read that sponges are toast the minute you remove them from the water......and yes I also think that is a sponge ....very nice. So what I am asking is did this get exposed to air during the rearrangement? 
I was just curious and hopeful for a few colorful hitchhikers like that within my live rock.(Or must they come later?)
